Bonjour it is a greenhouse, hot or cold. I think that with a temperature of 15 ° c mini it will work you put it at dormancy at what temperature ?

OK please let us know on the evolution of the problem

Bonjour do you know why in this book - the species P.toldensis is not taken into account - the variety P.jackii var parviflora has an invalid name merci , for your answers

if you have any doubt, quarantine it. what substrate use you ?

wait a bit to see the final aspect of the disaster, meanwhile make leaf cuttings it is often better to water by capillarity

Bonjour may be a picture but it seems rotten to me, maybe by too much watering?

Bonjour a good solution the bacillus thurigiensius for the larvae but not for the adult , uses for them yellow gooey plates , I think it is necessary to eradicate the 2 otherwise the problem will come back jeff

what substrate ? may be a adult sciarides ,your substrate is may be infected ? do you have larvae in your substrate ?

Bonjour do you grow these genus : rubiaceae ( myrmecodia-myrmephytum-squamellaria-hydnophytum-anthorrhiza)- asclepiadaceae( dischidia)-pteridophyte(lecanopteris-solanopteris) ? jeff

Bonjour do you grow this genus dorstenia ? jeff

P.vulgaris subsp vulgaris f albida , no?

may be just P.habilii for instant

Bonjour even compassion for all these people . jeff

Bonjour Have you flowers , may be too young ? jeff

Bonjour for your 'Weser' may be 'Sethos' for me your plant ,should not always stagnate in water, risk of rot. If it is not already too late put in the dry a few days. jeff

yes for P.alpina and P.vulgaris 'in situ' we find them both on limestone and acidic soils . But for other temperates rather on acidic soils or on many others , limestone soil jeff

Bonjour these plant in situ grow between 1400 to 2300m always in wet condition an for may to november even under the snow jeff

for cuban species some one grow in calcareous soils , but others on serpentin rock , others on tree trunk , other in white sand but rich in organic matter below you grow them in shade or full sun ? have you used, fish glitter, rather than a leaf fertilizer ? P.cubensis grow on serpentine rock always wet then with a big air hygromety sometimes in full sun,always also in 20-28 °c , According to some authors it would be annual 'in situ', and may be triannual in culture. I think that people more competent than me on these species will be able to better answer you. jeff

may be, though , but it is the first description(1893) of this abbe COSTE specie's and this name in FRANCE has been used for almost 70 years by many botanists in their descriptions, books ,etc . I find it pity to have forgotten it. jeff

Bonjour very nice success you grow them in pure sphagnum ? jeff

for infos see also on the E.PARTRAT site the F.ZUNINO work on the corolla morphological character find in the area CAUSSES here LINK noted also that this taxon in france had been called since 1893 ,when it was discovered ,P.longifolia var brevifolia ,it was not until 1966 that it call P.longifolia subsp caussensis jeff

Bonjour do you grow some species of this genus ? jeff

Bonjour oh excuse me ,I had understood that the 5 plants came from the Caucasus, so I spoke about new species for this area. now no problem have you a macro from the balcanica throat ? jeff

Bonjour magnifique ping all, for the caucasus mountains , but from what country ? the white may be a P.balcanica subsp pontica f alba , have you a picture to the sepals ? for the first and the last have you a throat macro picture ? the last is Particularly interesting , do you know it name ? may be a new specie ? jeff

Bonjour are you sure for the hoz de beteta taxon ,why not a P. mundi JEFF
