Derrick Posted March 27, 2014 Author Report Share Posted March 27, 2014 The above description notes that stems are often galled but I did not notice any examples; however, note the galled roots on this specimen. I have seen images of galled roots on other hydnophytums. 74c Hydnophytum longistylum. Note the unusual roots. Tunurua..JPG] Link to comment Share on other sites More sharing options...
jeff Posted March 30, 2014 Report Share Posted March 30, 2014 Bonjour difficult to see I have on the herbarium sheets : 2 leaves form for a same specie call longistylum may be H.stewartii = H.longistylum the leave apex on H.stewartii seem more pointed , no ? and other is very close H.vanuatuensis . if you want the herbarium sheet for these 4 leaves form , tell me. here on your picture the apex leave are more or less pointed , no ? you have not the flower macro with the stigma-anther and ring hair position? jeff Link to comment Share on other sites More sharing options...
Derrick Posted March 30, 2014 Author Report Share Posted March 30, 2014 Yes Jeff, I would like to see the herbarium images. Regarding possible identifications, I think without more detailed field studies of the 'species' natural variations, many current names should be considered only as temporary identifications. DNA studies and cross breeding experiments may also provide new classifications. Link to comment Share on other sites More sharing options...
jeff Posted March 31, 2014 Report Share Posted March 31, 2014 Bonjour no problem , but see my PM. I agree with you , when I see all the names , a lot must be synonymous ? jeff Link to comment Share on other sites More sharing options...
Derrick Posted April 10, 2014 Author Report Share Posted April 10, 2014 I can find no record of H. vanuatuense ever being published, so presumably it is a nomen nudum. Of interest is that it was originally compared to the Solomon Island's H. longistylum but it is now accepted as a new species. Perhaps an indication that H. longistylum will also be accepted as a definite species and not lumped into something else. From <http://plants.jstor.org/specimen/k000772005> Type of Hydnophytum vanuatuense Huxley & Jebb, collector, Green P. S. 5/8/1971. #1274. Locality, Erromanga, in the vicinity of the Nouankao Camp, (Erromanga Island) Vanuatu, altitude 150m. Past Identifications recorded on the herbarium sheet, Hydnophytum longistylum Becc. Verified by Green, P.S. 05/1974. Type of Hydnophytum vanuatuense Huxley & Jebb ; verified by Jebb, M., 12/1991 & again by Huxley, C.R., 1994. Notes on the sheet "Epiphyte with chambered tuber 30 cm. across; leaves palish green, ± succulent; flowers white, only one or two, sunk in the remains of old flowers and developing fruits; rain forest occasional (no ants seen because the host tree had fallen?" It is thirty years since this specimen was collected and it seems no description has been published. I think that if it had been as popular as for example an orchid or a cactus, a description would have been published decades ago. Link to comment Share on other sites More sharing options...
jeff Posted April 14, 2014 Report Share Posted April 14, 2014 This specie seem to me interesting. it seems to be the most southerly, with the fidjan species. jeff Link to comment Share on other sites More sharing options...
Frank Posted October 8, 2015 Report Share Posted October 8, 2015 An international group spearheaded by Guadalcanal islanders is currently doing a survey of high altitude plants in the forests of Guadalcanal: https://www.idigbio.org/content/discovering-new-plant-species-guadalcanals-mountains It will be interesting to see if specimens of Hydnophytum longistylum are refound - and what other species might show up, perhaps H. kajewskii? UPDATE: The expidition took place in Sept. of 2015. A preliminary report is here: https://www.usp.ac.fj/news/story.php?id=1955 Link to comment Share on other sites More sharing options...
Derrick Posted October 9, 2015 Author Report Share Posted October 9, 2015 Frank. I expect Hydnophytum guppyanum, H. longistylum, and H. kajewskii will prove to be quite common throughout the entire Solomons. However, an alpine ant-plant would be quite a find. We can but hope.

jeff Posted October 9, 2015 Report Share Posted October 9, 2015 Bonjour H.hellwigii seem present to Guadalcanal see the herbaria sheet to Bishop museum some Myrmecodia and perhaps some Anthorrhiza by chance , this country have a lot of islands some time little or no populated. this project is very interesting , if you have one day the result , sent us jeff Link to comment Share on other sites More sharing options...
Derrick Posted October 9, 2015 Author Report Share Posted October 9, 2015 The name Hydnophytum hellwigii is almost certainly a misidentification for a Solomon Island's collection. Indeed, the Bishop Museum specimen with this name is from the Atzera Range in Morobe Province on the north coast of PNG. http://www.gbif.org/species/2895794 http://nsdb.bishopmuseum.org/TaxonName/1666185727 Incidentally, this link supplies an excellent description of H. hellwigii with some habitat notes.

jeff Posted October 10, 2015 Report Share Posted October 10, 2015 Bonjour oh excuse me ,you should have seen H.stewartii ,instead H.hellwigii http://nsdb.bishopmuseum.org/TaxonName/-1682234750 jeff Link to comment Share on other sites More sharing options...
Derrick Posted October 10, 2015 Author Report Share Posted October 10, 2015 Jeff. The status of H. stewartii is detailed in "Epiphytic Myrmecophytes: Bizarre Wonders of Nature" along with a link to the authority concerned. http://www.biodiversitylibrary.org/page/8443412#page/22/mode/1up Link to comment Share on other sites More sharing options...
