Yes it may be correct if any one sees it as rare case but occurrence of Dendrobiums on said species is not rare case. It was shocking to see the paper having no info on it. That's why I reacted immediately But as Vijayashankar ji said it may be due to standard error, it is not the author's fault.
During the said visit I found insect species damaging Dendrobiums. I posted its picture to International experts but they asked for dead insects for correct identification. Due to laziness the samples are still with me. During visit on Shorea and other species mainly on orchids I observed heavy infestation of scale insects. The guides informed that this year infestation was at higher side. I searched the literature and based on it, in process of submitting a paper in journal. In short visit fortunately I got information about 30 formulations in which Dendrobiums are used. Hoping the Ethnobotanists from Jharkhand have reported it. I am sorry as always if I am encroaching your territories i.e. Jharkhand as well as Orchids. ;) regards Pankaj Oudhia On Sat, Mar 26, 2011 at 12:32 AM, Dr Pankaj Kumar <[email protected]>wrote: > I would love to see this report of yours on Mining Impact on Orchid > Diversity, if you can share. > There are distinct Orchid zones on trees, The one growing on the main > trunk is ecologically different from the one growing on the terminal > branches (twig epiphytes) hence it becomes tricky to understand if an > orchid grew by mistake of it really has a preference of the tree over > other trees. > Orchids have seeds without endosperm and hence they need to make > association with specialised fungi called mycorrhiza.
