epiphytic Liparis to identify please

[s.kallima]

I got this little plant for free at a show 2 months ago and it just bloomed now.
The pseudobulbs are 1 cm (.4") tall by .5 cm (.2") wide.
The flowers are on a long and very very thin and flexible stem, they are 1 cm tall and stay opened for 2 weeks. No scent. It is an epiphytic Liparis (from what the seller told me), which is not very common in cultivation, and it is from India apparently. This is all I know about it.

Thanks for your help
