  3. Bonjour The two mine, adult and that have fruited abundantly, I lost them unfortunately. They began to lose all their foliage, then were invaded by a kind of moss that made them die.

  23. 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
