Hi Derrick, which pictures are you referring to? The link point to the whole Facebook group?! All the best Andreas

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:

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

Hydnophytum spec. from "inland mangrove" near Siasiada village Certainly related to Hydnophytum radicans.

Huge Hydnophytum - possibly H. petiolatum - Milne Bay area - PNG The tuber certainly measures 50-70 cm in diameter

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:

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.

Anthorrhiza bracteosa Huxley & Jebb - Normanby Island - PNG

Anthorrhiza recurvispina Huxley & Jebb - Missima Island - PNG

Anthorrhiza recurvispina Huxley & Jebb - Rossol Island - PNG

Anthorrhiza caerulea Huxley & Jebb - Mt Kaindi - below summit - PNG A young plant:

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:

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
