This plant has recently been reclassified as part of a reworking of the massive genus, Pleurothallis. While I agree that the genus Pleurothallis, to which it originally belonged, was far too large and included too many dissimilar plants, I have trouble remembering all the new names. By any name, however, this is a lovely little plant.
This orchid is native to Costa Rica and is tolerant of a wide range of temperatures. The plant is 12 cm tall and the flowers which hide down at the base of the leaves are a little over 1 cm long. The plant seems to bloom several times a year for me. I have it growing in a specially thrown clay pot with extra drainage and in live sphagnum moss.
