Promenaea stapelioides

This is a miniature species from Brazil belonging to a very small genus  of 15-20 species.  Its specific name reflects the similarity of the flowers to those of a Stapelia, a South African succulent.  The plant is 8 cm tall and has small pseudobulbs and soft leaves.  It prefers cool temperatures and high humidity but when these requirements are met it is not a difficult plant to grow or flower.  The flowers are 3.5 cm and their green and purple colors make them a real showstopper.
