Otth were studied. The Silene specimens used in the study were collected from different localities between 2005 and 2007. Their conservation status, phytogeographical regions, and distribution in Turkey were determined. Detailed drawings of the general view and flower from each species were added to the study. As a result of these detailed investigations, the conditions of some species having taxonomic problems were re-examined, and suggestions were proposed. The results produced 3 taxa that are new to science and 2 taxa that are new records for the flora of Turkey. In addition, 5 species that were published as new species from Turkey were reduced to synonyms. Key words: Turkey, revision, Silene, systematic 1. Introduction Because of its geographical location, climate, and topographical and geological structure, Turkey’s rich flora is one of the most significant in the world. The main research into the flora of Turkey is Flora of Turkey and the East Aegean Islands, which was published from 1965 to 1988 and in 2000. There are 135 taxa belonging to Silene L. in 31 sections in Flora of Turkey; this has increased to 165 with the addition of new taxa (Coode & Cullen, 1967; Davis et al., 1988; Özhatay et al., 1999; Tan & Vural, 2000; Özhatay & Kültür, 2006; Özhatay et al., 2009; Kaya & Ertekin, 2009; Budak & Koç, 2011; Hamzaoğlu et al., 2011; Özhatay et al., 2011; Hamzaoğlu, 2012; Yıldız, 2012). The endemism ratio of Silene is 45% in Turkey. Moreover, there are errors and contradictions in the descriptions and identification keys of the species; a taxonomic revision of the Silene species was necessary. This study was conducted on species belonging to the 6 sections of the flora of Turkey: Siphonomorpha Otth, Lasiostemones Boiss., Sclerocalycinae Boiss., Chloranthae Rohrb., Tataricae Chowdhuri, and Otites (Adams.) Otth. Some taxonomic, karyological, and palynological studies have been performed on Silene species. In his study of the Silene Chowdhuri (1957) examined a total of 443 species that have a worldwide distribution in 44 sections. The information presented regarding these sections in addition to some problematic species was used as the main source by Coode and Cullen (1967) during the writing of the genus Silene for the Flora of Turkey. Melzheimer (1977) biosystemically revised the Silene taxa that are distributed in the Balkans. Wringley (1987), on the other hand, handled the Otites section and examined the species in this section according to their taxonomical, karyological, and palynological properties. In the palynological study conducted by Ghazanfar (1984) on 44 taxa represented in the sections Siphonomorpha and Auriculatae, Silene italica (L.) Pers. and S. viridiflora L., which were revised in our study, were also included. In their study of an endemic taxon, S. cserei Baumg. subsp. aeoniopsis (Bornm.) Chowdh., Vural and Adıgüzel (1996) showed the differences between this taxon and S. vulgaris (Moench.) Garcke, which shares similar features with the studied species. Yıldız and Çırpıcı (1992, 1996, 1998, 2000), Yıldız (1996, 2001a, 2001b, 2002, 2005, 2006a, 2006b), and Yıldız et al. (2008, 2009a, 2009b, 2011) emphasized the morphological, palynological, and karyological features of the taxa in their study of the Silene and proposed solutions for dealing with the problems. In the current study these suggestions were considered and solutions to the problems presented were studied. As stated above, in the literature there are taxonomical, morphological, karyological, and palynological studies * Correspondence: kemalyil@gmail.com 191 YILDIZ and ÇIRPICI / Turk J Bot on the Silene, a significant genus in terms of biodiversity. Moreover, the majority of these studies are limited ones conducted on several species. Some of them are general and cover several families and genera, and these include a number of the Silene species; however, they are not specific. Because of the absence of a comprehensive and detailed study on the species growing in Turkey, a taxonomic revision of the genus Silene was undertaken. Considering the difficulty of examining all the taxa within a single project, in the current study the revision of the first 6 sections of the flora of Turkey was undertaken. 2. Materials and methods The taxonomic revision of the genus depends on intensively collecting plants from the research area, evaluating them, examining previously collected specimens, and investigating the flora-systematic studies about Silene. With this in mind, distribution of the Silene taxa, inflorescence periods, and habitat were determined by using various studies in the Flora of Turkey and the East Aegean Islands, vol. 2 as well as herbaria and field observations. Then samples of Silene species were obtained from almost every region of Turkey during field work between the beginning of July 2005 and the end of August 2007. Some of the collected samples were dried according to standard procedures and saved as herbarium specimens, and others were placed in 70% alcohol for use in morphological investigations if needed. The identified plants were kept in the Celal Bayar University Biology Department, Faculty of Arts and Sciences and the Marmara University Faculty of Arts and Sciences Herbarium (MUFE). Research about the genus Silene in the European flora, the flora of neighbouring countries, and especially the Turkish flora, was used for identification (Hegi, 1959–1979; Chater & Walters, 1964; Zohary, 1966; Hayek, 1970; Meikle, 1977; Melzheimer, 1988; Greuter, 1997). Silene specimens primarily in the herbaria of ISTE, ISTF, ISTO, ANK, GAZI, HUB, and EGE along with AIBU, ATA, ANES, KNYA, VANF, GUL, Erciyes Univ. Herb., Akdeniz Univ. Herb., Çukurova Univ. Herb., and the Virtual Herb. of the Lake Van Basin were examined, and their photographs were taken. The significance of the type specimens in the taxonomic studies was considered; the images of type specimens of Silene species studied were obtained from the Berlin (B), Kew (K), Edinburgh (E), Geneva (G), Vienna (WU), and Cambridge (CGE) herbaria; and the images of 15 taxa were obtained. Furthermore, the images of the type specimens in the Linne Herbarium were viewed via the web site. The identification keys of the studied species and descriptions of new species published after 2000 were presented in this study. Descriptions were realised based on the samples collected during the current research and evaluated in various herbaria by considering the related literature. World distribution of the species, phytogeographical regions, conservation status, chromosome numbers, and drawings of the species were presented in the study. 3.

Nyman, and subsp. peloponnesiaca Greuter] in the Flora of Europe and Flora of Greece. Only subsp. italica displays a distribution in Turkey. S. sieberi, which is given as the synonym in the Flora of Turkey, is accepted as a separate species in the Flora of Europe and Flora of Greece. This species is endemic for Crete. 194 2.

In the Flora of Turkey there are 2 varieties of S. gigantea: var. gigantea and var. incana. Greuter evaluated these varieties in the Flora of Greece (Flora of Hellenica) as subspecies (Greuter, 1995). The evaluation in this study is based on Greuter. 4. S. amana Boiss., Fl.

Threatened category: CR-B2b+D. Chromosome number: 2n = 24 (MUFE 12297) (Yıldız et al., 2008). This species was only known from type gathering but was collected from the same region many times during this study. It needs to be protected since it has a limited distribution. It is similar to S. viridiflora L. and S. italica. Nonetheless, it can be very easily distinguished from the other 2 species according to its morphology. S. italica’s basal leaves obovate to lanceolate, cauline leaves linear to spathulate. Petal limbs bipartite to 1/2, coronal scales absent. Gynophore 7–15 mm. S. viridiflora’s basal leaves linear to triangular subulate; cauline leaves narrowly lanceolate or ovate-lanceolate. Petal limbs bipartite to 3/4, 2 coronal present. Gynophore 1.5–2 mm. But S. amana’s basal leaves ± elliptic, spathulate, cauline leaves ovate-cordate. Petal limbs bipartite to 2/3, 2 coronal scales present. Gynophore 10–11 mm. 5. S. viridiflora L., Sp. Pl., (ed. 2) 1: 597 (1762), (Figure 2) (Yıldız & Çırpıcı, 2000). Type: described from Portugal (Hb. Linn. 583/27, photo!). Turkey; South, West, and Central Europe; CrimeaSiberia and East Asia. Widespread. Chromosome number: 2n = 24 (MUFE 12092) (Yıldız et al., 2008). It is generally distributed in Northern Anatolia, in Mount Amanos, and shows a surprising split in the Flora of Greece. This is because the western section of Mount Amanos has a climate similar to that of Northern Anatolia. 196 S. lesbiaca P. Candargy is the synonym of S. flavescens Waldst. & Kit. subsp. thessalonica (Boiss. & Heldr.) Nyman in the Flora of Greece. In other words, S. lesbiaca, which is given as the synonym in the Flora of Turkey, is actually not the synonym of S. viridifora. 6. S. phrygia Boiss., Fl.

The petals divide into 4 lobes in the MUFE 12337, 12342, 12351, and 12405 specimens. Nonetheless, petals had 2, 4, and 5 lobes in the MUFE 12406 specimens collected from the same region and same habitat in this study. Therefore, the number of petal lobes is not enough to distinguish these 2 species; however, it was concluded that S. ispartensis and S. phrygia should be the same species since all other features coincide. Thus, S. ispartensis is reduced to a synonym of S. phrygia. Section Lasiostemones Boiss., Fl. Orient. 1: 574 (1867). 7. S. longipetala Vent., Descr. Pl. Nouv. 83, t. 83 (1802) (Figure 3).

S. lasiantha Koch was evaluated as the synonym of S. marschallii subsp. marschallii in the Flora of Iran. Nevertheless, there are distinctive differences as a result of the data obtained from this study, and it would be suitable to evaluate them as different species. The hairiness characteristic is used for distinguishing S. marschallii from S. lasiantha, but the main distinctive character is the flowers, which are more widely branched in the former. 9.

Otth in the Flora of Turkey, indicating it was close to S. otites (L.) Wibel. Nonetheless, this species is significantly different from S. otites as regards plant height, leaf size, sexual condition, and inflorescence. On the other hand, it displays characters that are more similar to S. capitellata. Although the flowers in S. capitellata are capitate, they are usually clustered on the stem in S. isaurica. Furthermore, flowers in S. isaurica are either hermaphrodite or female; all of the flowers in S. capitellata are hermaphrodite. S. isaurica also exhibits similarities with S. olympica and S. lasiantha as regards plant size, inflorescence, branched stem, and leaf arrangement. S. isaurica, because of the aforementioned features, was included in the section Lasiostemones. 12. S. olympica Boiss., Diagn. Pl. Orient. ser. 1(1): 24 (1843) (Figure 4) (Yıldız & Çırpıcı, 2000). 1.

S. olympica, S. lasiantha, and S. capitellata are very similar to each other.

Threatened category: EN-B1a+C1+D. Chromosome number: 2n = 24 (MUFE 12430) (Yıldız et al., 2009a). S. idaea displays a great similarity to S. caramanica. It was considered a new variety of S. caramanica. The hairlessness of the stem, with serrulate leaves or not, and the differences in calyx length were the distinguishing characteristics between the 2 species. Nonetheless, these characteristics did not show a correlation in this study; for example, MUFE 12298, 12299, and 12321 specimens display S. caramanica features as regards stem base hairiness and absence of serrulate basal leaf margin, while they show S. idaea features as regards calyx length. Likewise, the specimen numbered MUFE 12005 shows S. caramanica features as regards calyx length whereas it displays S. idaea features as regards presence of serrulate leaf margins. The other specimens studied display similar conditions. Therefore, S. idaea could not be a different species. The same conditions were also observed by Huber Morath, and he presented S. idaea as the synonym of S. caramanica (Candollea, no: 35, 1980). Since S. idaea is different from the other varieties of S. caramanica, it was considered a new variety of S. caramanica. Plant specimens, along with S. kucukodukii Y.Bağcı & Uysal specimens, that were collected from regions where the type specimens display distribution were evaluated [Konya: Hadim to Bozkır 5 km, 1700–1750 m, 10.07.2005, K.Yıldız 027-1 & M.Y.Dadandı (MUFE 12069!); Konya: Hadim, nr.

Discussion The revision of the sections Siphonomorpha, Lasiostemones, Sclerocalycinae, Chloranthae, Tataricae, and Otites of the genus Silene, which is represented by 164 taxa in the Flora of Turkey, was conducted in this study. The images of type specimens belonging to 16 species were obtained from various herbaria, photographs from the Flora of Iran belonging to 5 species were used, and 13 species were collected from their type localities. Although S. phrygia was only known from its type specimens it was collected during this study. The presence of S. viridiflora, usually distributed in Mount Amanos, northern Anatolia, was interpreted as a surprising split in the Flora of Greece. This may be due to the fact that the western sections of Mount Amanos have a climate similar to the climate in northern Anatolia. It was noted that S. caesarea and S. sclerophylla, which are recorded as endemic in the Flora of Turkey, also appear in the Flora of Iran (Melzheimer, 1988). Therefore, S. caesarea and S. sclerophylla were not endemic for the Flora of Turkey. S. ruprechtii Schischkin, the synonym of S. saxatilis, was presented as a valid species in the Flora Iranica (Melzheimer, 1988). S. saxatilis M.B. (not S. saxatilis Sims) was regarded as the synonym of S. ruprechti in that Flora. S. peduncularis was presented without specifying localities in the Flora of Turkey, based on the doctoral research by Chowdhuri (1957). Nonetheless, this species was obtained from localities within Gümüşhane and Bayburt provinces in this study; thus, its existence in Turkey was proven conclusively. S. lycaonica, which was known only from type specimens and was considered endangered (EN) in the Red Book of Turkish Plants (Ekim et al., 2000). It was collected from West and South Anatolia many times and was determined LR (cd) in Turkey. S. cartileginea was recorded from Van, Gürpınar, Çuh Gediği, Hakkâri, and Cilo mountain in the Flora of Turkey. It was not possible to collect these species during field work for this study. Thus, the investigation of this species was based on the previously collected herbarium specimens. When the studies on Silene were examined, it was observed that Chowdhuri (1957) arranged the Silene species into 44 sections and determined the features of the sections, whereas Melzheimer (1977) biosystemically revised the Silene taxa in the Balkans. Although pollen features in this study showed some differences among species, they did not reach a level appropriate for distinguishing among species; however, seed testa features included diagnostic characteristics that could be used for distinguishing species and subspecies. During our studies we observed that great similarities between some species and variation among the species do exist. S. italica, which is not separated into subspecies in the Flora of Turkey, was separated into subspecies in the Flora of Europe and the Flora of Greece [subsp. italica, subsp. nemoralis (Waldst. & Kit.) Nyman, subsp. peloponnesiaca Greuter] and into varieties in the Flora of Bulgaria. From the examinations conducted it became clear that all of the samples in Turkey were S. italica subsp. italica. Moreover, S. sieberi, which was presented as the synonym of S. italica in the Flora of Turkey, is actually not the synonym of this species; it was an endemic species growing in Crete and was not distributed in Turkey. Although the Flora of Turkey considered S. splendens very similar to S. italica, these 2 species are easily distinguished from each other by the differences in their leaf forms and veins (Figure 1). Signifying that it had not been available for collection for a long period of time, S. amana was put into the category of DD (deficient data) in the Red Book of Turkish Plants (Ekim et al., 2000). Nonetheless, this species was collected from its type locality and surrounding localities by the researchers. It was concluded that the species, which has a rather limited distribution, should be categorised CR-B2b+D. There are 2 different varieties of S. gigantea, var. gigantea and var. incana. Greuter (1997) evaluated these species as subspecies in the Flora of Greece; and also changed var. incana to subsp. rhodopea, and took into consideration their distribution in Turkey while accepting these subspecies. The evaluation in the current study was based on Greuter. The most important difference between these 2 subspecies is that lateral cymes are closely spaced, and their calyxes are generally simple and infrequently glandular haired while lateral cymes are loose and calyxes are very infrequently glandular haired or hairless in subsp. rhodopea (Figure 1). S. phrygia (Figure 2) is a species that was first published in Flora Orientalis (Boissier, 1867). Its type specimens were collected from B2 Usak and C2 Antalya. S. ispartensis was represented as a new species by Ghazanfar in 1983. Ghazanfar signifies that S. ispartensis displays great similarity with S. phrygia; it was reduced to a synonym of S. phrygia. A new subspecies of S. marschallii was identified for Turkey during this study (Figure 3) and presented to the scientific world as S. marschallii subsp. anamasi (Yıldız et al., 2010). S. lasiantha was given as the synonym of S. marschallii subsp. marschallii in the Flora Iranica (Melzheimer, 1988). In this study, however, distinctive differences between these 2 species were observed, and they were evaluated as different species. The most significant morphological difference was that the flowers of S. marschallii were more widely divaricated. Silene erciyesdaghensis (Aksoy et al., 2008), which was recently made a new species, was distinguished from S. olympica (Figure 4). In the evaluation conducted on S. erciyesdaghensis no distinctive difference was observed 213 YILDIZ and ÇIRPICI / Turk J Bot between these 2 species. S. erciyesdaghensis differed from S. olympica in that the lower flowers are capitate or 2(–3) distant verticillasters, and the flowers are pedicillate in a strict raceme or paniculate and petal divided 1/3 to 1/2. The characteristics mentioned in the paper are shown in the table below (Table 1). Detailed studies conclude that S. erciyesdaghensis is not a different species but a variety of S. olympica. Silene isaurica was presented as a new species by Contandr. and Quézel in 1976. In the Flora of Turkey S. isaurica was similar to S. otites, and was therefore included in the Otites sections. On the other hand, it was observed that plant height of S. isaurica was shorter than S. otites and its features are different from those species as regards leaf size, sexual condition, and inflorescence. This species also displays similarities with S. capitellata, S. olympica, and S. lasiantha. S. isaurica, because of the aforementioned features, was included in the section Lasiostemones. Although the flowers capitate at the top of the stem in S. capitellata, they are usually clustered in S. isaurica. Likewise, flowers in S. isaurica are either hermaphrodite or female; all of the flowers in S. capitellata are hermaphrodite (Figure 4). S. bupleuroides, which is not separated into subspecies in the Flora of Turkey, is separated into subspecies in the Floras of Europe, Iran, and Greece. In the examinations conducted on this species it was determined that S. bupleuroides had 2 subspecies in Turkey: subsp. bupleroides and subsp. solanocalyx. The most significant difference between subsp. solanocalyx and subsp. bupleuroides was that bracts of the former subspecies were elliptic-lanceolate and flower buds were not included (Figure 5). S. caramanica and S. idaea display great similarities according to their morphological characteristics. The distinctive characters of these 2 species, such as their hairiness condition, shape and size of basal leaves, and length of calyx, were evaluated; and it was found that the aforementioned characteristics did not show any correlation. It was determined that MUFE 12298, 12299, and 12321 specimens displayed both S. caramanica and S. idaea characters regarding basal stem hairiness, absence of serrulate basal leaf margin, and calyx length, respectively. Likewise, the specimen MUFE 12321 displayed features of S. caramanica regarding calyx length, whereas it displayed features of S. idaea when its serrulate leaf margin is considered. Similar conditions were observed for the other specimens evaluated in this study. Huber-Morath (1980) did not find the diagnostic characteristics adequate to distinguish between the 2 species and presented S. idaea as the synonym of S. caramanica. Since the observations in this study show similarities with the findings of Huber-Morath, it was concluded that S. idaea should be a variety of S. caramanica. The final condition of S. idaea is displayed as S. caramanica Boiss. & Heldr. var. idaea (Hausskn.) K.Yıldız & Çırpıcı (Figures 5, 6). One of the new species that was presented to the scientific world by this study is S. aydosensis (Yıldız & Erik, 2010) (Figure 6). This species is distributed in south and south-western Anatolia. S. aydosensis shows a similarity with S. caramanica and S. doganii (Figures 5,6). Their most distinguishing features of the species are the morphological structures of their basal leaves. Silene bitlisensis is a new species that was introduced to the scientific world by Tugay and Ertuğrul (2008). While S. bitlisensis was presented as a new species, samples of S. caramanica, S. bupleroides, and S. idaea, which are close species, were evaluated. S. bitlisensis was not compared Table 1.

Instead, it was compared with the more distant species. Therefore, significant differences were determined in the species that were alleged to be close to the new species. In the current study, specimens of S. bitlisensis collected from their type localities and various herbaria were examined and identified as S. sclerophylla. When the specimens of S. bitlisensis and S. sclerophylla were compared (Table 2) these 2 species were observed to be the same. Thus, S. bitlisensis is the synonym of S. sclerophylla (Figure 8). Silene kucukodukii, which was introduced to the scientific world as a new species by Bağcı et al. (2007), show a great similarity with S. sipylea (S. caramanica var. idaea); and it can be distinguished from the species with regards to hairiness, leaves, and flower characteristics. The type specimen (K.Ertuğrul 2927 & O.Tugay, KNYA!) was compared with the numerous samples obtained from its type locality and its surroundings (MUFE 12068, 12069, and 12331). As a result of these evaluations, it was concluded that S. kucukodukii should be the synonym of S. caramanica, as indicated in Table 3. Table 2.

These changes are given in the table below (Table 4). In conclusion, Silene gigantea var. gigantea and var. incana taxa were changed to subspecies S. gigantea subsp. gigantea and subsp. rhodopea, respectively. S. isaurica was transferred from the section Otites to the section Lasiostemones. S. bupleuroides was separated into 2 subspecies, subsp. bupleuroides and S. bupleuroides subsp. The existence of a new species, distinguished from S. eremitica, was discovered during the current study. The species was introduced to the scientific world as Silene demirizii (Yıldız et al., 2010). S. demirizii can be distinguished from S. eremitica because its basal and stem leaves are thinner, more linear, hyaline, papillose; inflorescence panicle, petal lobes shorter, and seeds bigger. Silene densiflora d’Urv. and S. exeltata are synonyms of S. otites in the Flora of Turkey; however, S. densiflora is a valid species for the Flora of Turkey and it is a new record for the Flora of Turkey.
