    Hi Marcel,

    No doubts for the beauty of your plants and your skillness to grow these plants !

    The Hoz de Beteta is clearly not i : a P. vallisneriifolia or a P. longifolia subsp. longifolia. See below if your plants have glands on both sides ?

    I have also the same king of protection against blackbirds ! awfull but without it. It cost me all my P. villosa this year !

    Dear Eric,

    very nice plants! It's quite amazing how variable these plants are.

    I only have plants with greenish leaves that looks like a hybrid of P. longifolia x grandiflora for me but for the others I'm not sure.

    Cheers,

    Matthias

    For me, I think also of an hybrid (and maybe multiple back crosses) of P. longifolia sub. longifolia with P. grandiflora

    I should have somme gemmae in automn if you want

  9. Using plastic trays under fluorescent lights

    in Propagation

    Posted

    I use translucent plastic shoebox size trays indoors under fluorescent lights for all of my CP. The UV light produced by the fluorescent lights was so actinizing that in less than a year of use the top edges of the trays, the portion receiving the most light exposure from the fluorescent lamps, would begin to crumble. I tried applying tape to the edges, but it was time-consuming and too easily the tape would interfere with manipulation of the trays. So I tried using white spray paint formulated for use on plastic surfaces and lightly sprayed just the edges where the trays would be closest to the lights. Now, after having used the spray painted trays for as long as five years, only three or four out of almost one hundred have failed from extended exposure to the lights.

    Hi Joseph,

    It depends also of what kind of plastic you have.

    Polyethylen (PE) or Polypropylen (PP) are known to be more resistant to UV rays that Polychlorid Vinil (PCV). No idea for Polystyren (PS) maybe not suitable for long term use.

    Thanks for the idea of plastic painting.

    FERNANDO for me this population is very interessant .

    to know, why these plants side by side have different color would interest me much.

    to know if this plants keep allways their colour and if their seeds keep this caracter also.

    to put a form reference for me under these conditions is not very absurd , still once we must use all the infraspecific name of the taxonomy

    sp,subsp,var and f

    in taxonomy the epithete 'red ' or 'green ' is not valid

    jeff

    Maybe it is a lack of anthocyanin like we can find many plants in Sarracenia. I am not expert for this.

    The same with P. alpina can be noted :

    Just about the P. vulgaris from Reims with perfectly round seed cap FOR ALL THE THREE POPULATION

    Pinguicula vulgaris from Reims

    You can see what Laurent Legendre noted about the notable differences with this local form in Chapter 4.

    Sorry for the quality but this copy may have 12 years. All pefect pdf quality copy is welcome...

    I remimber a "hot" discussion with Laurent, Jan Schlauer and Jurg Steiger. Jurg and Laurent found this population very interesting and that could reach a form rank and Jan close the discussion saying if I remimber well "just another Pinguicula vulgaris variation, publications are full of it". It was many years ago.

    Not easy to say if it is or not an hydrid for this P. longifolia colony from Pineta cliff.

    When I was there, I found an infinite variations of flowers.

    As I wrote in A WORLD OF PINGUICULA - > See the article

    " Many plants fall down from the cliff and try to survive at the bottom under heavy water flow. Some can also follow the numerous rivulets and arrive in the bog but no plants seems to survive there ! Despite a population of P. grandiflora subsp. grandiflora in the bog, the presency not far of P. longifolia subsp. longifolia and the arrival of fallen plant (but no survival), we didn't note any hybridation. "

    I didn't note hrybridation in the bog but maybe on the fall insects can pollinate on the cliff after the bog ?

    Speaking of new forms, there is one of P. vulgaris near the city of Reims in France, with isolates populations (maybe extinct now) of P. vulgaris with round seed boxes for all the plants !

    See the picture here : pinguicula vulgaris from Reims

    And many others pictures from Reims

  13. Pinguicula martinezii

    in Carnivorous Plants in Habitat

    Posted

    Quick translation "The new species distinguishes from Pinguicula agnata by the rosettes of “winter” compact leaves with 16 to 38 leaves, spatulates to oblong-spatulates; the“summer” rosette formed by 6 to 14 leaves narrowly spatulates, of 60 to 100 mm in length, by 13 to 25 mm in width and flowers of 13 to 25 (30) mm of length (including the spur). However in P. agnata the winter rosette is constituted by 12 to 20 leaves more espatulates thicknesses, with the apex cleared to obtuse; the leaves of “summer” rosette are espatulates to obovado-oblong, of 35 to 110 mm in length, by 15 to 50 mm in width; The flower measures of 20 to 34 mm in length (including the spur). The habitat in which both species are growing is very contrasting: P. martinezii grows in vertical limestone rock walls in the forest mesófilo, between 2000 and 2370 m of altitude and P. agnata in crevice or walls of limestone rocks in non-evergreen tropical forest, submontano scrub or forest of encinos, in a altitudinal repartition that goes of 350 to 2000 ms of altitude.

    Hi Fernando,

    thank you for your great report and the photos of P. martinezii.

    It must have been a cool trip though you didn't find P. calderoniae at all.

    Do you plan to go there at a better time in future to find it in full growth/bloom?

    I must admit that P. martinezii is not a good species at all in my opinion.

    It is too similar to P. agnata and I guess that an amateur wouldn't recognize the differences.

    You wrote in the article that P. martinezii is the only member of the P. agnata complex that forms winter rosettes.

    It is true that the description of P. agnata says that it doesn't form a winter rosette. But this is a false fact because

    the species were described by herbarium specimens only and the author didn't know about the life cycle of this plant.

    Cheers,

    Markus

    Hi Markus,

    Following your message, I must also say that I have some P. agnata at home forming winter rosette and longer summer leaves and it is not P. martinezii as not in culture yet in Europe.

    P. ibbarae is really different with its "moranensis" like summer leaves and "agnata like" winter leaves.

    Speaking also about the P. agnata "CSUF", it made me think of a P. ibbarae but I must study more.

    Dear Andreas,

    Thanks a lot and as writen priviously, what a discovery with this unusual growing habit and morphological plant comparatively to the others south andies Pinguicula.

    I noticed on P. antarctica and P. chilensis the use of prodcing plantlets on underground stolons. Do you know if this species are reproducing also by this sometimes (I just think of the rhizome like under the rosette) ? forming hibernaculum ? gemmae ?

    If you didn't written that it was a south andies Pinguicula, I would have written that it was a European Pinguicula in a typical growing habit !
