K 2852 25 November 2020 – Orchidaceae : 1 very high res. image.
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.
pleiten spec : 1 image.
If someone owns the name of this orchid I would be happy.
I thought of Pleione.
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.
