I humbly believe this to be Oberonia only, but as I said, its a matter of taxonomic opinion.

Yes it looks Oberonia in first view. Flowers are very minute.

Yes I have written in the mail that i think it should be kept with Oberonia!!
In Uttarakhand this is known as Oberonia myosurus.

The correct name of this plant is now Oberonia cavaleriei Finet.
