Encyclia alboxanthina
 

This is a large Encyclia species that gives tall panicles full of green and white flowers. It inhabits the Chapada Diamantina in the centre of the State of Bahia. When I visited Diamantina I saw it only one time in the Mucugê area, but I guess it is not in any danger.

Never heard of this one...but then with 900 of so Epidendrums, that'sot surprising! It is certainly floriferous!
