This is the smallest orchid species in my collection with leaves to about 1" long and yellow/red blooms up to about 1/16th of an inch!
I grow it on a stick and it grows quickly flowers continuously when I remember to water and feed it often (as evidenced by the spent flower stalks). If I don't remember to water it very often due to other concerns the leaves are very thick and succulent and it weathers dry spells easily, quickly resuming active growth and blooming when I start to water it again. The more water and food it gets the faster it grows and more it blooms.
To propagate it I simply pluck a strand of rhizome with a few leaves and roots on it and tie it gently to a piece of bark or another stick with some moss on it to conserve moisture. In a few months it will establish and begin colonizing it's new mount and start to flower as each growth matures. A great LITTLE, easy species in Highland conditions! I have found it doesn't grow as fast in a pot and the rhizomes tend to rot.
