  1. H. virgatum Val. (Theodoric Valeton) Just's botanischer jahresbericht. Systematisch geordnetes repertorium der botanischen literatur aller länder, vol.61, p142, (1927). (Bot. Jahrb. Syst.), not yet digitised. Update. Jebb & C. R. Huxley, The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum, Blumea 64, p86, (2019.) With illustration and a member of their Uncertain and Little-Known Species. Type, Ledermann 11646, 11701, 11849 (Bogor Herbarium not seen, presumed lost), Papua New Guinea, East Sepik Province, Schrader Mountains. I have found a more recent collection claimed to be this species using Valeton’s key, but these are not types. Takeuchi (1995) Papua New Guinea, Madang Province, Bismarck Range. http://data.biodiversitydata.nl/naturalis/specimen/L%20%200074528 And. http://data.biodiversitydata.nl/naturalis/specimen/L.2913882 Collection notes. Ant-house epiphyte, tuber brown, completely obscured by roots and debris, leaves coriaceous, dark green, mid green below, inflorescence axillary, sessile, pauciflorous, flower 4 merous, yellow. Papua New Guinea, Madang Province, ridge overlooking campsite 4, at 600-900 m.
  2. H. subsessile Val. (Theodoric Valeton) Just's botanischer jahresbericht. Systematisch geordnetes repertorium der botanischen literatur aller länder, vol.61, p142, (1927). (Bot. Jahrb. Syst.), not yet digitised. Update. Jebb & C. R. Huxley, in The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum, Blumea 64, p86, (2019.) A member of their Uncertain and Little Known Species. Type, Lauterbach 3164, (B not seen, presumed lost), Papua New Guinea. The only herbarium placement I can find is an endorsement of H. linearifolium var. subsessile on the type sheet for H. linearifolium. I repeat here. Type, Ledermann 9700. (1912) appears to have been labelled H. linearifolium var. subsessile but the writing is not clear. http://data.biodiversitydata.nl/naturalis/specimen/L%20%200000491 And https://plants.jstor.org/stable/10.5555/al.ap.specimen.l0000491

Syst.), not yet digitised. Update. Jebb & C. R. Huxley, in The tuberous epiphytes of the Rubiaceae 7: a revision of the genus Hydnophytum, Blumea 64, p85, (2019.)

Huxley note “K not seen, presumed lost” Papua New Guinea, Madang Province, Huon Peninsula, Finisterre Mountains at 300m (984 ft.) Yet here it is. http://apps.kew.org/herbcat/getImage.do?imageBarcode=K000761951 This specimen has distinct, long and somewhat narrow leaves. Merr. & L.M. Perry note when referring to H. ramispinum. “In leaf-size and flower, this species (i.e. ramispinum) is near Hydnophytum stenophyllum Val. and H. punamense Lauterb. In both the latter species the leaves are either attenuate-acute or acute, and in neither is there any mention of the furfuraceous character of the young bark. Unfortunately, many of the species have no indication of the characters of the tuberous base. (Elmer Drew Merrill & Lily May Perry) Journal Arnold Arboretum Vol 26, pp23, (1945) (J. Arnold Arbor.) http://www.biodiversitylibrary.org/page/8443412#page/28/mode/1up
  4. Jeff. That drawing of a specimen in FLOWER represents a TYPE of the basionym. The following sentence is from my opening post of this thread. "Carnevali (2009) also states that: "This beautiful species was described by James Bateman in his classic book 'The Orchidaceae of Mexico and Guatemala' published as pl.30, in 1843 as Schomburgkia tibicinis, from plants collected by George Ure Skinner in Guatemala. This is correct," This URL links to THE holotype of the basionym Schomburgkia tibicinis with a description and further notes in Latin and English. Thus, even if you wish to ignore the expert work of Rolfe and use the basionym, the following flower is correct for tibicinis and Robert's flower is not. "Petals nearly equal, very much curled, upwards of an inch long, dark chestnut brown inside, and dirty purple without." http://www.biodiversitylibrary.org/item/15471#page/105/mode/1up
  5. Hello Andreas. The links normally work but their server seems to be having problems. Try this method. but it too is currently having problems. Click on www.philippine plants.org Then click on Angiosperm Families. Scroll to Rubiaceae, then to Hydnophytum. I see that Dr Pieter Pelser has already ascribed most names to H. formicarum or H. moseleyanum after Jebb & Huxley 2019. H. angustifolium is kept separate.
  6. A while back I suggested to Co's Digital Flora of the Philippines that some photos in their database may represent this species. Jebb & C. R. Huxley (2019) have it listed under their little known species. I suspect this may be a rare situation where we amateurs can provide professionals with new evidence. https://www.facebook.com/groups/philippineplants/ Incidentally, this site is run from little New Zealand. H. angustifolium Merr. (Elmer Drew Merrill) The Philippine Journal of Science. Section C, Botany 3, p162, (1908) (Philipp. J. Sci., C.) Descriptions in Latin as then essential, and in English. http://www.biodiversitylibrary.org/page/673338#page/185/mode/1up Merr. Leaflets Philippine Botany, Vol 3, Art 54, p1038, in English. (Leafl. Philipp. Bot.) http://www.biodiversitylibrary.org/page/776329#page/277/mode/1up Merr. Notes. A very characteristic species, readily recognizable by its narrow sessile leaves, the nerves of which are obsolete or nearly so, and its elongated fruit. Tuber irregular, at least 15 cm (6 inches) in diameter, brown or grayish, unarmed. Stems several, diffusely branched, at least 60 cm long, gray or brown, slender, the branches elongated, younger ones, brown, furfuraceous (covered with flaky scales), somewhat angled. Leaves lanceolate or narrowly lanceolate, 5-10 cm (2-4 inches) long when dry, somewhat shining, gradually narrowed at base and apex, tip acute or blunt, midrib prominent beneath, lateral nerves obsolete or very obscure. Flowers fascicled (bundled) in axils, white. Calyx cylindrical 1 mm., long and wide, truncate. Corolla 2 mm long, inside slightly barbate at the middle. Anthers 0.7 mm long. Style 1-2 mm long. Fruit red, somewhat fleshy when fresh, to 1 cm long, about 4 mm m diameter at the base, gradually narrowed upward, apparently 1-celled with a single seed. Update. Jebb & C. R. Huxley (2019) were unable to place this in their concepts of H. moseleyanum or H. formicarum or “most especially H. puffii” due to a lack of herbarium specimens, that are possibly lost. Habitat/Range. A forest epiphyte at 200-600 m (656-1968.5 ft.), Mostly in the southern islands, yet common on central Sibuyan Island. Zamboanga & Lanao Del Sur Provinces, Mindanao Island, Philippines. The following images possibly represent this species. http://131.230.176.4/imgs/pelserpb/r/Rubiaceae_Hydnophytum_plant2_49811.html http://131.230.176.4/imgs/pelserpb/r/Rubiaceae_Hydnophytum_plant2_49820.html http://131.230.176.4/imgs/pelserpb/r/Rubiaceae_Hydnophytum_plant2_49818.html http://131.230.176.4/imgs/pelserpb/r/Rubiaceae_Hydnophytum_plant2_49817.html
  7. This is an authentic type image of Myrmecophila tibicinis. The above image is not tibicinis under whatever historic genus one wishes to place it. http://www.botanicus.org/page/769219 This type image was referenced in my opening post but the URL used then no longer works.
  8. As I update Epiphytic Myrmecophytes: Bizarre Wonder of Nature 2019 (currently almost through chapter 9, Hydnophytum, I uncovered quite a number of hints of what to expect in a revision. About a week ago someone on the WWW reported that this revision was imminent but I found that vary hard to believe. We had waited soooo long. I now have to re-evaluate this entire chapter that has already involved many months of work. It has been designed primarily as a searchable a database, supported with photographs wherever possible. So it probably still has value for a wide range of enthusiasts. I do wonder how much will change as botanists apply ever more molecular genetics in their work; for example, some of what are only suggested manuscript names may need to be resurrected. My database probably has most of them.

  12. Jeff. I suggest you check a lot more herbarium sheets. I have already checked at least 100 sheets of radicans and possibly associated species. I found that the leaf shape of species accepted as H. radicans by the experts is surprisingly LARGE. To the degree that leaf shape has very little influence on the defining features of this species. My initial thought was that DNA evidence might change our understanding of what defines H. radicans. Yet Dr Guillaume Chomicki's acceptance of the H. kiense specimen above, suggests NO. He certainly is using DNA in his work, but I cannot guarantee DNA tests were performed on this particular specimen.

  14. Here a Kew Type specimen originally labelled H. keiense is assigned to H. radicans by Huxley 1992. Weri Bandan, Kai Besar (formerly Kei) Island, south east Moluccas archipelago (Spice Islands), Indonesia, (Isole Kei, Bandan a Weri. Isole = island, Kai Besar being the largest. Bandan is a political/population centre, Weri means stream.

Of the species of Hydnophytum already described from New Guinea, this one superficially suggests H. Hellwigii (sic) Warb., but differs considerably in particulars. Apart from small leaves, distinctive characters specify, flowers in alveoli surrounded by bracts and long brown hairs; calyx with cilia 0.5 mm. long, also brown; corolla glabrous within; anthers closely affixed by the middle of the back, only apices exserted.

  20. It seems that H. auridemens may become a variety of H. petiolatum if the Jebb & Huxley revision is ever published. This is from Chomicki et al., support information. He obviously has access to the unpublished manuscript. I have added huge volumes of data to Epiphytic Myrmecophytes: Bizarre Wonders of Nature. 2019. Currently I am working on chapter 9 Hydnophytum. It alone contains over 88,000 kilobytes of data and images. H. auridemens Jebb & C. R. Huxley in press. Replaces manuscript name H. missima (sic.) H. petiolatum var. auridemens in press. Description. Tuber irregular, often containing rainwater. Bract hairs orange-brown, dark brown when wet. Habitat/Range. High-level epiphyte at 300-400 m (984-1312 ft.) in lower tropical forest to lower montane open forest, on south slopes of Mt Sisa, Misima Island, Louisiade Archipelago, Milne Bay Province, Papua New Guinea.

  23. There are claims on the WWW that the domatia within tubers of Microgramma are created by ants eating tuber contents, I suspect this is incorrect except that resident ants may enlarge upon plant produced domatia. Has anyone cultivating tuberous microgrammas confirmed this?
