Indonesia now officially uses the term "West Papua" for their part of the island. So, now there is PNG and West Papua. Link to comment Share on other sites More sharing options...
Aurélien Posted February 24, 2014 Report Share Posted February 24, 2014 Impressive! The flowers rallies it undoubtfully to the genus Myrmephytum, but it doesn't look like toe anything know in the J&H revision! Or maybe one of the two elusive "Myrmephytum species" from PNG quoted on page 51? But a "species" of Myrmephytum without flowers nor tuber... The "species 1", collected by Kanehira & Hatusima (Dalma, Nabire) and informally named Myrmedoma longissima have long and narrow leaves, 4*44cm... So mysterious plants...

Hi Aurelien, West Papua and PNG are not really well explored. I'd bet that there are many undescribed really good species out there, waiting for discovery.

Derrick Posted February 25, 2014 Author Report Share Posted February 25, 2014 Triton Bay is actually on the south side of Bomberai Peninsula, West Papua, the one below the Birds-head Peninsula. http://www.esa.int/Our_Activities/Observing_the_Earth/Bird_s_Head_and_Bomberai_Peninsulas_of_Indonesian_Papua Map here. http://www.papua-insects.nl/about%20Papua/Wandammen/Wandammen%20Peninsula.htm Link to comment Share on other sites More sharing options...

The "species 1", collected by Kanehira & Hatusima (Dalma, Nabire) and informally named Myrmedoma longissima have long and narrow leaves, 4*44cm... So mysterious plants... When seeing these images for the first time, I too thought of a connection to the Nabire collection but I then realised that this Myrmephytum (see images) has a somewhat Myrmecodia-like thickened stem that we see in lone Myrmephytum arfakianum (http://myrmecodia.invisionzone.com/index.php?/topic/151-myrmephytum-arfakianum/) which was previously placed in Myrmedoma because of such a thick stem. All other myrmephytums on record have rather hydnophytum-like stems. Hence I discarded this idea because M. arfakianum was the only species known to me that had myrmedoma-like stems and the notes on page 51 merely say "stem unbranched." Yet it now seems probable that calling the Nabire collection "Myrmedoma longissima" indicates it also has thick stems. I must have read the name Myrmedoma longissima on page 51 but failed to connect the facts. Tut tut, more rewriting for me. Link to comment Share on other sites More sharing options...

In fact, yes, that's a little bit far from the Nabire location where 'Myrmephytum sp. 1' was collected. And I agree with you Andreas, this genus as well as many Papuan plants lacks a lot of field informations... Link to comment Share on other sites More sharing options...
Derrick Posted February 26, 2014 Author Report Share Posted February 26, 2014 Trying to decide if these images represent more than one species seems futile without access to the plants; however, my guess and it is no more than an idle guess, is that there is only one species represented above. However, I now think it probable that it is "Myrmedoma longissima" which presumably will become Myrmephytum longissima when validly published.

jeff Posted February 26, 2014 Report Share Posted February 26, 2014 it is may be futile but here it seem to me see 2 species , pictures are sometimes a good approach in a first time. we do not see some inflorescence contignous apical part of stem on the first picture . on these others 2 yes , it seem to me that the spines on the tuber are not arranged in the same way, the leaves on the first picture seems longer and more slender. Myrmedoma longissima is not a Myrmecodia longissima we find also this one in IRIAN JAHA and PNG BECCARI speak to the genera Myrmedoma like this: caulis et folia myrmecodiae , flores fasciculati, bracteis magnis coriaceo-herbaceis involuti , corolla 6 loba . on the HUXLEY &JEBB description the tuber and the flower are not known ,then why a myrmephytum ? have you some documents to this NABIRE COLLECTION ?

Andreas Wistuba Posted February 26, 2014 Report Share Posted February 26, 2014 Seeing this species and considering my finding in the McCluers gulf of West Papua, I'm planning to spend more time in the coastal lowlands during my next trip to West Papua Link to comment Share on other sites More sharing options...
Derrick Posted January 24, 2015 Author Report Share Posted January 24, 2015 As Jeff noticed there is already a Myrmecodia longissima; therefore, if this plant proves to be the same as the old Myrmephytum collection from Nabire, it will have to be given a new specific name.

jeff Posted January 30, 2015 Report Share Posted January 30, 2015 Bonjour although the 2 nd pictures is quite far taken no opportunity to see the tuber and the stem some differences between the two swings me in the eyes:- Leaves : 2 or 3 times larger than the tuber, more thin (almost linear lanceolate) with a short petiole.- tuber : enough ridged with spines for me may be a myrmecodia but a picture of the stem and the flower will comfort me more for the others 2 ,surely myrmephytum , the same ? the leaves seem to me differente very ondulate for one then surely 2 new taxons jeff Link to comment Share on other sites More sharing options...
Aurélien Posted January 30, 2015 Report Share Posted January 30, 2015 But the flowers on picture 1 are hexamere! Does I mislead if I say that the difference between Myrmecodia and Myrmephytum is precisely that the first have 4-mere flowers and the second 6-mere?

jeff Posted January 30, 2015 Report Share Posted January 30, 2015 yes, but the first picture are the flower of the plant in the second picture ? if yes , I revised my position of course, but we need proof anyway for me 2 candidate of new taxa jeff Link to comment Share on other sites More sharing options...
Aurélien Posted January 30, 2015 Report Share Posted January 30, 2015 Indeed, we need to be sure that flowers on 1st picture own to the plants on other pictures. Look at the bracts on the 3rd one: really large and leathery, like Myrmephytum. I never seen Myrmecodia with such bracts. Link to comment Share on other sites More sharing options...
