  6. 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

  19. for M.beccarii on clypeoli it seem that spines sometimes present , scaterred. but wait and see afterwards just an other question , how many pyrene : 4 or 6(8) jeff
  20. 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
  21. 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
  22. 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
  23. Bonjour ROBERT great success , you also on the 2 last picture , it seem to see M.beccarii ,especially seeing the small annex stem on the principal stem , no spines rimming clypeoli (or what appears to be one) wait and see later jeff
