Conchidium braccatum (Lindl.) Brieger (= Eria reticosa Wight),
wild epiphytic orchid from Siddhapura area of Karnataka, similar species available in Dendrobium also, So there is some doubt in the ID
No this is Trias (Bulbophyllum). I need to check the closeup of flowers to confirm species.

It is my pleasure to share few images of Trias stocksii (Orchidaceae)
Habitat: Epiphytic, Evergreen forest
Sighting: Kottigehara, Chikmagalur, Karnataka, about 1200 msl
Trias stocksii flowering: Photographed on my property at Shahapur today.
This is very much like Trias stocksii, but the colour is so yellow.
T. stocksii that I know has more of reddish brown or reddish yellow flowers. … can you please check this your plant. There is another species, Trias bonaccordensis both endemic to India. By the way, this should be a new record for Maharastra what ever species it may be.
what tree is it growing on?
does it have a favorite tree to grow on?
Yes! I too am surprised of seeing the flowers that are single colored ones, that too yellow. The one that we get here in further south is brownish/reddish with purple/dark brown/red blotches on the center. This is not even Trias bonaccordensis. Please refer the following link which is a reliable one as far as I experienced, so far.
This is something different.
I want … to please preserve some flowers in 70% alcohole and if possible please make a herbarium of the specimen with flowers.
Trias stocksii starts flowering here (from Central Karnataka towards further south) by February.
I missed this mail earlier among the 100’s of mails in my inbox, when I came back from the field.
Further, I feel the leaves and bulbs are also different, I mean smaller than Trias stocksii . Shape of leaves are also somewhat different.
Yes …, I too have the book by …, right now on my table. To me it looks different. There are 6 species of Trias in India namely, Trias bonaccordensis, T. crassifolia, T. disciflora, T. nasuta, T. oblonga and T. stocksii. I am nto sure if the plant pic matches properly with any of these.
Color is like hat of T. oblonga but shape and size of petals are not. http://www.orchidshome.com/gallery/trias/#6
Please look for more Trias on other trees and see whether they also possess the same flowers or different. I, now, think some modification of Trias stocksii. Even then, it would be quite interesting since you can multiply this species asexually.
Is there Trias oblonga nearby areas?
Thank you all for your feedback. Based my diagnosis on the photographs of T.stockii seen in the book ‘Wild Orchids of NW Ghats’ by Dr.Satish Pande et al. The orchid featured here is growing on a Teak [Tectona grandis] tree, though most are seen on Lagerstroemia lanceolata [L.microcarpa,Seena,Bhondara] trees. Have not noticed any Trias oblonga orchids, but will keep a check.
Sending a few photographs of the flower-buds taken 2 weeks prior.
The color of buds (outer perianth) also looks different. Please keep an eye on the orchid on other trees as well for flowers and see the same is happening with plants on other trees as well.
Thanks … for putting up your points.
The main issue here is, Hooker didnt talk anything about the colour of the flowers in his original description. So such issue may arise. At the same time, thinking of occurrence of another new species in India is not overruled.
…, yes orchids are generalists as well as specialists in choosing their host trees. But this aspect is understudied in India. I wish if someone could have worked on such topic and come out with some great results.
yes that would be a study worthwhile to do…
Orchid seeds dont have endosperm of its own. So to germinate it needs help from a special group of fungi called mycorrhiza. These mycorrhiza are very much habitat specific too. If you remember some basics of
yes thank you, truly… it answers the curiosity for a while…
Lovely plants. Now called Bulbophyllum stocksii.
