I posted another species from this genus recently, Mediocalcar versteegii. Like that species this is from New Guinea and a rambler. Each growth grows on top of the previous growths and the plant, as a result, forms a dense mat of growths. This plant, however, is much small, each growth only 2 cm tall, and thus it is much easier to contain and can even be grown in a pot as mine is, though the roots do not stay in a pot. The growths are little cylindrical pseudobulbs with three or four fat little leaves at the top of each like a little propeller and with flowers look like little candies. The plant was given both a Certificate of Botanical Recognition and a Certificate of Cultural Merit by the American Orchid Society many years ago. It prefers cool temperatures and good humidity but is easy to grow.
