Background: Ecbolium hastatum Vollesen is currently known from only three collections in southern Mozambique and has not been relocated since 1970.Objectives: To document two new populations and a small range extension for this poorly known species, and to provide a much-needed assessment of its conservation status.Method: The new populations were found by the first author (W.M.) while conducting floristic surveys of coastal thicket vegetation between Inhassoro and Vilanculos in December 2016, and during ongoing surveys by the second author (A.M.) of coastal thicket between Ponta de Ouro and Inhassoro. No voucher specimens were collected for the northern population, but photographs of key features were taken and compared with specimens in online herbaria. A voucher specimen was taken for the southern population.Results: Two new populations and a northern range extension for E. hastatum are recorded. The species is assessed as Endangered EN B2ab(iii) according to International Union ...
An annotated checklist of the 271 strict-endemic taxa (235 species) and 387 near-endemic taxa (337 species) of vascular plants in Mozambique is provided. Together, these taxa constitute c. 9.3% of the total currently known flora of Mozambique and include five strict-endemic genera (Baptorhachis, Emicocarpus, Gyrodoma, Icuria and Micklethwaitia) and two near-endemic genera (Triceratella and Oligophyton). The mean year of first publication of these taxa is 1959, with a marked increase in description noted following the onset of the two major regional floristic programmes, the “Flora of Tropical East Africa” and “Flora Zambesiaca”, and an associated increase in botanical collecting effort. New taxa from Mozambique continue to be described at a significant rate, with 20 novelties described in 2018. Important plant families for endemic and near-endemic taxa include Fabaceae, Rubiaceae and Euphorbiaceae s.s. There is a high congruence between species-rich plant families and endemism with ...

Memecylon sect. Buxifolia R.D. Stone (Melastomataceae, Olisbeoideae) is a group of forest shrubs and small understory trees distributed from tropical East Africa (Kenya and Tanzania) to eastern South Africa and with a disjunct occurrence in Madagascar. Previous authors had recognized three species of this section as occurring in Mozambique, i.e., M. natalense Markgr., M. torrei A. Fern. & R. Fern. and M. insulare A. Fern. & R. Fern. Here we describe four new species of M. sect. Buxifolia from Mozambique and adjacent parts of Malawi and Tanzania: Memecylon incisilobum R.D. Stone & I.G. Mona, M. nubigenum R.D. Stone & I.G. Mona, M. rovumense R.D. Stone & I.G. Mona and M. aenigmaticum R.D. Stone. In accordance with previous molecular results, M. incisilobum and M. nubigenum are semi-cryptic species that had been confused with M. natalense (considered here to be a South African endemic). Memecylon rovumense and M. aenigmaticum had also been confused with M. natalense, but their conspicuously verrucose-wrinkled fruits indicate a closer affinity with M. torrei. We assess the conservation status of each new species according to the IUCN Categories and Criteria, and provide an identification key to the seven species of Memecylon currently recognized in the flora of Mozambique.
Synsepalum chimanimani S.Rokni & I.Darbysh., sp. nov., a small tree endemic to the forests of the southern foothills of the Chimanimani Mountains of Mozambique and Zimbabwe, is described and illustrated. The differences in morphology and distribution between the new species and the related S. kaessneri and S. muelleri, with which it has been confused, are clarified. The new species is globally Endangered due to ongoing habitat loss within its restricted range. The botanical importance and conservation of the Chimanimani foothills is also discussed, and they are highlighted as a candidate Important Plant Area.
