Hoya for id from Siliguri:: NS June 09 : 13 posts by 6 authors. Attachments (5). This beautiful epiphyte was shot near Siliguri (W.B.).. This is a Hoya sp. ...H. verticillata ?? Please give your opinion regarding specific id.. Wow, great find ... Hoya alright since I photographed H. carnosa a few days ago here in California. Looks ver similar. Would be helpful if we know the differences. Thanks for your early inputs ... I was considering this being one from H. verticillata or H. carnosa .. tha pictures of the tiny flowers are so beautiful...they almost look artificial. Hoya verticillata, acuta and parasitica are all quite difficult to differentiate. If there are references on the flora of Bengal, it could help A reply from maker of World site on Hoyas: "I sure looks like a species from the parasitica complex, but it's extensive and flowers come in many colors (also growing condition affects the color) so it's difficult to pin point exaclty which one" Attached here KEY of three Hoya in 'Bengal Plants'. Attachments (1). Roxburgh's note on Asclepias parasitica reads, "....... leaves opposite..... firm fleshy texture... veins scarcely conspicuous above, and invisible underneath, ..... petioles short, round, ash coloured, in fact more like a part of a branch...." But, Wight's illustrations shows leaves are pinnately veined. I do not know if this is the same as Hoya parasitica Wall. ex Traill. A website provides some information on Hoya - http://www.psthehoyan.com/. The author throws some light discussing H. parasitica, H. acuta and H. verticillata. According to him Hoya acuta does not have tri-nerved leaves. Also, Hoya verticillata does not have tri-nerved, quinquenerved, or palmately veined leaves (please note the graphics in http://www.psthehoyan.com/psthehoyan3_4.htm). The author further informs, "The Hoya sold in trade as H. acuta ...... are .... clones of H. pottsii." FoC has only one species with 3-veined leaves - I hereby do not attempt to ID your plant. I send you this mail only because I have spent past two hours just to know what Hoya is! Whatever species it may turns out it is a heavenly (if there is any!) creation.... and excellent photographs as well. Thank you very much for sharing this wonderful finding. Pl. also see Hoya acuta Herbarium sheet marked as Hoya verticillata (Vahl) G. Don can be found at KEW -
The No.1, 3 & 4 above have tri-nerved leaves. But no.2 seems to have penninerved leaves and one leaf in the no.3 herbarium also is pennineved. Can this Hoya be labelled as H. parasitica (Roxb.) Wall. ex Wt.?
Attached images are Hoya parasitica. The accepted name for the species are Hoya parasitica (Roxb.) Wall. ex Traill synonym of Hoya verticillata (Vahl) G. Don(According to India Biodiversity Portal) , Hoya parasitica Wall. ex Wight (According to Tropicos), Hoya parasitica (Roxb.) Wall. ex Wight(according to eFl of India), Hoya parasitica Wall. ex J. Traill(According to Biodiversity Heritage library and The Plant list) and Hoya parasitica Wall. ( according to JSTOR Plant Science)and Hoya parasitica (Wall. ex Hornem.) Wight (according to Kew world checklist of selected plant families). Now which is the correct Bot. name for Hoya parasitica.? Date :25.06.2017 Location: Assam Family : Apocynaceae/Asclepiadaceae Genus & species : Hoya parasitica Habitat: Grows as epiphyete on tree Habit : Epiphyte To me appears to be same plant as in another thread: Hoya for id from Siliguri:: NS June 09 (still to be confirmed) |
