I love this species too, Bob, wherever the taxonomists move it. I've got 
three or four clones and always will. The flower is beautiful, but I'd 
grow it for the fragrance alone. Whenever one flowers, it comes up to 
the house for a few days.

I need to check - I know I bought a small var. fimbripetala a couple of 
years ago, but I don't recall seeing that pot recently ...

> As to the plant itself:  Like many green- or white-flowered orchids, it is pollinated at night, and the strong lemony fragrance turns on and off like clockwork.  At night the perfume will fill a room.  The specimen shown is the rare 'fimbripetala' variety, in which the whiskery theme on the lip is continued on the petals.  The effect is pretty cool.  The foliage is thick, succulent, and very leathery so not surprisingly it wants a LOT of light.  I grow in chunks of coco husk on the south wall of my already brutally hot greenhouse, next to the Rhy. glauca and the more light-loving bifoliate Catts.  It seems to enjoy it there.
