  1. Hi Derrick, which pictures are you referring to? The link point to the whole Facebook group?! All the best Andreas
  2. Here are some pictures I took of Hydnophytum/Myrmecodia mamberameonse (nomina nuda) in the Bogor herbarium. Yes there are big similarities, but stems seem much more elongated:
  3. Dear Jeff, I agree, that the likelihood is there that it is in fact this species. However, if you look at my photographs below, I guess you'll agree that this species neither belongs into Hydnophytum, nor into Myrmecodia. At first sight, it looks like a Myrmecodia, but aprt from the the unique inflorescence, tuber lacks the highly organized architecture of Myrmecodia and the inflorescence. One of my thoughts was as well that this in fact shows a species related to Hydnophytum mamberamoense (nomen nudum) but the plants I found were much more compact. I did not see any of the elongated stems as shown on the herbarium sheet. In any case I believe, that the plant shown in my pictures represents a new genus. All the best Andreas
  4. Huge Hydnophytum - possibly H. petiolatum - Milne Bay area - PNG The tuber certainly measures 50-70 cm in diameter
  5. Lecanopteris sinuosa - Normanby Island Certainly the most extreme form of this species I saw so far. The "thorns" from which the leaves emerge are much bigger than in the other varieties I saw so far:
  6. Myrmecodia spec. - Mt. Kaindi - below summit - PNG This species certainly is related to M. horrida, M. ferox and M. gracilispina. However, the leaves are much more spathulate than any of these species and the shoot is far less spiny. This species, however, shares the "ant tunnels" in the shoot.
  7. Anthorrhiza bracteosa Huxley & Jebb - Normanby Island - PNG
  8. Anthorrhiza recurvispina Huxley & Jebb - Missima Island - PNG
  9. Anthorrhiza recurvispina Huxley & Jebb - Rossol Island - PNG
  10. Anthorrhiza caerulea Huxley & Jebb - Mt Kaindi - below summit - PNG A young plant:
  11. Anthorrhiza chrysacantha Huxley & Jebb - Mt Kaindi - summit - PNG This picture nicely shows the typical branching of this species. The smaller leaves with less prominent lateral veins, the smaller, less undulate leaves and this characteristic branching pattern sets A. chrysacantha apart from the otherwise very similar A. caerulea:
  12. Hello Jeff, I frequently have sporelings in the greenhouse but they never became weedy such as other ferns. I was sowing spores in vitro. No problems. All the best Andreas
  13. The problem is the transfer of content. I do not know if there is any way to extract the content to transfer to another forum. All the best Andreas
  14. I'm very glad that Frank gives this forum another chance after I decided to step back. Good luck!!! All the best Andreas
  15. A herbarium sheet with a name tag put on it on is not a publication. Without a valid publication it's a nomen nudum. These rules are very clear. All the best Andreas
  16. Not really. I have plants mounted on bark that look like a good match. When potted, this species exhibits quite different characteristics. All the best Andreas
  17. Hi Jeff, while I understand the importance of floral morphology, it often is not very realistic to obtain them. Even more, since this often leads to destruction of the main plant. In the wild, I often saw and photographed plants that were hanging 15-20 meters away with a big tele-lens. How would you obtain the details in such cases? Even more, fruiting and flowering in the wild is not such a frequent event.... I often have flowers here in the greenhouse but find it incredibly difficult making preparations of flowers without destroying parts of the flowering plant - which is a no-go for me. If you are good in doing non-destructive preparations, you are invited to come here and do some preparations. I can do the next steps doing macro-photography but honestly, my fingers are too thick and my 48 years old eyes are too bad to do the preparations... All the best Andreas
  18. This species seems to be related to Myrmephytum "species 1" and the ones from Triton Bay. However the caudex is always pendent hanging with the help of thick roots and it is much more elongated than in species 1. In comparison, "species 1" is always attaching itself to the tree with its broad base. The flowers are much more delicate than the flowers of the plants from Triton Bay.
  19. Hello Frank, hello Jeff, just see the collection number. It's essentially the same as one of the doubtful Myrmecodia species mentioned in Huxley and Jebb: The taxon found by Elisabeth has absolutely nothing that reminds me to Myrmecodia. So I would strongly doubt that this is the one. Please check the leaf attachments on the herbarium sheets: Indeed, the specimen on the sheet looks like a Myrmecodia with a drastically elongated stem.
  20. Hello all, as requested, I just created a "Beginners Corner". You may ask all questions you don't dare to ask in the more "sophisticated" sub-forums here, or just chat with other members. All the best Andreas
