I got this plant in fairly early spring from Maui Orchids as an adult, mature plant that was a division of their own. I have to say that I purchased it mostly because it cannot any longer be found in its native range which makes me feel incredibly sad.
Maui Orchids claimed it is a cooler grower while other sources say warm grower - I don't know the right answer so I grow it in my Masdevallia area (cooler side of intermediate) and it seems happy. It came with two flower spikes, one with blooms that fell shortly after its arrival however this plant can bloom for years off of the same spike and now I have many buds and blooms, one group pictured above. Interestingly, the blooms that it came with had chocolatey brown petals and sepals while this blooming is almost completely white. The previous blooms also smelled like almonds (to me) while these seem unscented. I may email Maui Orchids to determine how they grew theirs - perhaps it is cultural differences.
Even when out of bloom, I consider it to be quite a lovely plant. It has long, 2.5' canes with soft, broad and laceolate leaves that are beautiful grass-green in color. I grow it somewhere between Oncidium and Cattleya light, placing it just a little off set from a south-facing window with light diffused by other Catts that are directly in the window. It's still in the 3.5'' pot and chunky bark mix that it came in so I water a bit more at about twice a week. It seems to really like being misted down so I give it a nice, light mist when I do my mounted plants. Since it's the Masdie room, humidity is on the high side, typically 60-75% during the day and 70-80% at night.
I would really like to cross this plant with another of its species from a different source and send the pods off to the Troy Meyers Conservatory for flasking. If anyone happens to have one, I would love to trade some pollen!
In the end, I look forward to the day where I have my own home and can make this a center piece as it is a really lovely plant. I don't have any good places to take a photo of the whole thing but I really recommend looking it up.
Here's an article from the NY Times from 1990 that briefly talks about its discovery and subsequent loss from its natural range. If you have a subscription to the Times, you can read the full article:
