Found in the Western Ghats.

Bulbophyllum sp

Its always helpful if you can be precise about the location of this plant.
If I had to guess, I would say Bulbophyllum rosemarianum. But cant confirm without the flowers.

It seems to be Bulbophyllum sterile (Lam.) Suresh

Very nice….Orchid treat…!

number 3 pic are those dried flowers with seeds developing?

Thank you very much …

…, the third picture is of the reddish-brown variety of flowers seen in some individuals in the same or nearby populations. Came across this marked difference quite often and made sure that the yellow flowers matured and dried as yellow flowers only and there were young reddish-brown coloured flowers in some individuals.

thanks. so do you have pictures of yellow flowers that dried yellow? if yes can i see them please?

Unfortunately I do not … If possible on my next visit, I will certainly click them.

Presenting few images of Bulbophyllum sterile (Orchidaceae 


Habitat:Epiphytic,semi-evergreen forest fringe. 

Sighting:Kottigehara,Chikmagalur,Karnataka,about 1000 msl 

Date:07-01-2017 and 08-01-2017

I imagine why this is not rosemarianum? I always get confused.

One of my friends suggested that this could be B.rosemarianum because of the short and squat pseudobulbs and if it were sweet smelling. I remember  to have sniffed the flowers but were odourless or definitely not foul-smelling.

Those flies are sitting on the flower, and they are always attracted to the smell, so the flowers must be having some smell and specially foul one for those flies.

sorry with those flies, it can be both foul or sweet smelling.

Kindly look @ this link and the images contained there in.

Ref http://florakarnataka.ces.iisc.ac.in/hjcb2/herbsheet.php?id=2993&cat=1

I don’t follow this website and I know it has lot of mistakes.
The basic mistake here is the name itself.

Thanks for your thoughts …

the best and easiest way would be to go and smell it again.
Please remember that flies get attracted to SMELL….

Thanks for the suggestion…..will do it and comeback to you

Re-visited the specimen as suggested by you. Though I did not smell anything foul two of my team members were unanimous that it smelt a little bit foul…! As you mentioned there were flies…..this time I found many small ‘fruit-fly’ like flies hovering around. I am uploading an image of one such fly that I could photograph. I think that this info helps in nailing the ID.

Here are icones of B. rosemarianum and B. neilghrrense (= B. sterile)

I always thought they are differentiated on the basis of smell, rosemarianum (fruity) and sterile (foul). 
May be they should be merged. But the leaf in your pic is comparatively shorter as I think rosemarianum has much monger leaves.
Column and labellum structure matches very well in both. May be they should be merged.

Thanks … for the vivid explanation…..I will take it as B.sterile in my files for the time being.
