Published by RGoB and RBGE. 2002 from Bhutan Biodiversity Portal) My friend has sent one image to verify if this is D. longicornu or watti, shot at 2500m. in November 2015 in East Nepal. I am unable to see what I wish to see. You need to show me a spread-up labellum Ok ..., He has only this image. multiple pics from multiple angles are always helpful. I know ... But he had only this image ! I am unable to see if the front lobe of labellum has distinct constriction on either side. But somehow after looking again, I feel this is Dendrobium longicornu. Need more pics to confirm.
If someone owns the name of this orchid I would be happy. I thought of Pleione. Flowering; october Altitude: 2300m Growing at a tree along a humid small stream broder. Dendrobium longicornu ! I am again a bit confused here. I should call this Dendrobium longicornu but the flower on my right hand side shows a constriction, I imagine if it is just a damage or true constriction because I cant see the same on other flowers. |
