  1. Bonjour JAY merci for these infos. you have try just stem cutting , the leaves cutting do not start ? the rooted stem cutting give tuber ? jeff
  2. Bonjour very interesting method JAY , and really the plant is sprouting new growths on the upper edge of the wound ? you use this method on a healthy plant or a damaged plant. I tried that too on a plant that began to rot, I had removed all the damaged part with a cutter blade until reaching the healthy part ,Then I sprouted with charcoal powder,Unfortunately the result had not been convincing. may be ventilation was not sufficient ? have you try leaf or stem cuttings ? jeff
  3. salut ANDREAS you try not directly on peat ? jeff
  4. Bonjour have you try , spore seedling on lecanopteris or solanopteris jeff
  5. Bonjour ROBERT yes I have a light problem , but I can not explain the head rot,And when I cut, the stem divides and stays healthy. jeff
  6. WAOUH . very nice collection . jeff
  7. Bonjour For my part I had a lot of loss on juveniles, last year, head rot. The only way I have found to remedy it, for those who remain is to cut off the head. may be have you an others solutions ? jeff
  8. Bonjour FRANK what medium use you ? sphagnum ?dead or alive ? no peat? have you a lot of mortality in your juveniles ? jeff
  9. Bonjour it is not a question but a answer for me a registered herbarium sheet is greater than a non-exhaustive list, but that's just my opinion. for IPNI see here : IMPORTANT: IPNI does not have information on what are currently accepted names and what are taxonomic (i.e. heterotypic) synonyms. Find this information in floras, monographs, checklists, revisions etc. amicalement jeff
  10. Bonjour but we have some herbarium bogoriense sheet with some registration number ( LEIDEN), it is not sufficient , find in borneo in 1925 and 1956 Furthermore these H.extendifolium specimen is very well preserved , and very close to this H."perangustum" and H.puffii JEFF
  11. Bonjour While this is indeed a good thing. but we must also take into account other similar Hydnophytum has this P. Perangustum in different herbaria that can be seen compare 2 different plant has no interest for me. I would have like it compares this P.puffii with P. extendifolium for example
  12. Bonjour very good infos but some problem nevertheless this DERRICK info : So it is to be an official name if it does FINALLY get published. Currently we may use Hydnophytum perangustum Jebb & C. R. Huxley in press. However, for some unknown reason this is taking an extremely long time to be published, but It is evident that copies of Jebb & Huxley's Hydnophytum revision have been shared with some academics. then 2 names for the same species ? may be also H.extendifolium from borneo ? I am OK with JAY on the picture , but on the morphological characters I see tuber subglobose to slightly compressed ovoid ,it could do so , no? jeff
  13. Bonjour ROBERT it is a nice surprise can you tell us : the actual temperature and the % hygrometry thank for the answer. jean françois
  14. Bonjour ROBERT I have 2 flower section to D.pectinoides the second seem to me good can you help me JEFF
  15. I understand the problem 'in situ', I'm not so obtuse. In the other genus that interested and for which I am often 'in situ', it is also difficult and each details can be important for the determination or to discover new species, sub species, varieties or forms. you do not have confronts you in this for the Heliamphora? 'ex situ' although this is difficult, it's sometimes more, look J, it happens well, although sometimes the macro are not very sharp and difficult to interpret, he made some great discoveries. sacrificing one or two flowers in my opinion it is not a drama. for Aurelien species, between tuberosa 'armata' and tuberosa 'muelleri' may be this could bring him more. jeff
  16. Bonjour to make expeditions in these regions, it is necessary to have money and a good physical condition, unfortunately I do not have those two things. the europe for some others genus, is already quite large So I work mostly on past and current documents in our possession , like you it seem to me . as a botanist I like to have correct and complete descriptions for determinations. for these plants, these morphological details -tuber -stem -leaves -inflorescence -flowers -fruit Pictures make not everything, we also need other elements like flowers section . in all publications, all these details are described , why not do it ? jeff
  17. Bonjour may be if you have a inflorescence section , you can discriminate between M.tuberosa 'armata' and M.tuberosa'muelleri' may be areas where they were found, gives good info jeff
  18. Bonjour in the KAREMA province you have others tuberosa species like tuberosa 'versteegii' why not this one ? this one is pendent ,with some branched spines , with also several stem . jeff
  19. Bonjour excellent in this country a lot of tuberosa species exist , perhaps 4-5 difficult to discriminate just on the fruit colour jeff
