Derrick Posted March 21, 2019 Report Share Posted March 21, 2019 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 Quote Link to comment Share on other sites More sharing options...
Andreas Wistuba Posted March 22, 2019 Report Share Posted March 22, 2019 Hi Derrick, which pictures are you referring to? The link point to the whole Facebook group?! All the best Andreas Quote Link to comment Share on other sites More sharing options...
Derrick Posted March 22, 2019 Author Report Share Posted March 22, 2019 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.

Derrick Posted March 30, 2019 Author Report Share Posted March 30, 2019 Further to this thread. Here are two herbarium specimens attributed to H. angustifolium by Adolph D. E. Elmer in 1910. Collection not type. Elmer (1910) Philippines, Sibuyan Island, Capiz Province, Romblon, Magallanes (Mt. Giting-Giting) http://data.biodiversitydata.nl/naturalis/specimen/U.1561946 http://data.biodiversitydata.nl/naturalis/specimen/L.2913092 Update. Jebb & C. R. Huxley have referred these two specimens to H. formicarum in their recent revision. I am not convinced. Quote Link to comment Share on other sites More sharing options...
