Barbosella australis

Barbosella australis is a rather common miniature orchid species from Brazil (the name "australis" means "southern").  It should be grown on a mount and forms a creeping mat of small 1.5 cm leaves and produces flowers that larger than the leaves, about 2 cm long.  I received this plant as Barbosella cogniauxiana from a vendor who ought to know better and was a bit annoyed to find that it was not correctly identified, though the flowers are beautiful in their own right.
