I have found some Cymbidium family orchids in Waynad (Kerala)

Cymbidium bicolor
(Above two pictures)

Again I am referring to Dr. T. Ananda Rao's Book.

Plate - 23: Picture Number : 73

Oberonia ranganniana

This one looks close to Dendrobium herbaceum
(Plate - 12, Picture Number:33)

Tommarow I am going to Waynad. I will see if I can find any orhcids there
