Pretty flowers and beautiful pic. Yes Bulbophyllum rosemarianum.


Where you got this from?


This was in premises of one of “tropical spice gardens” that have come up in Goa.
The orchid was growing wild; it did not look planted – because this site was along the quarter km entry path.
Very good find. Not mentioned in Mah flora BSI


Thanks … for validation; this one is from Goa. Normally found distributed further south.

A kind of Bulbophyllum


This is Bulbophyllum sterile (Lam.) Suresh (Orchidaceae).


The plant you have forwarded is Bulbophyllum rosemarianum which is from Orchidaceae and found in Western ghats of Maharashtra, Goa, Karnataka and Kerala.
I have an inquiry to all of you that as i am working on Genus Dipcadi Family Liliaceae of Maharashtra so i am searching for locations of its species. As  have collected most of them but in case of Dipcadi concanense i want more data on its collection sites. If anyone has collected the plant from anywhere in Maharashtra please forward me the details of site of collection.


As per my observations there is no difference between Bulbophyllum rosemarianum and Bulbophyllum sterile only colour variations. One of our Botanical Assistant had seen both type of colour differences in same bunch of Bulbophyllum sterile in Mookambika Wildlife sanctuary in Karnataka. Bulbophyllum rosemarianum is described by Dr. Satish Kumar in Rheedea 2001.
