Rubellia (Pleurothallis) rubella - Orange Lip Form

Rubellia (Pleurothallis) rubella - Orange Lip Form, originally uploaded by Duane McDowell.

This is another cutie from Colombia (formerly known as Pleurothallis rubella). It's a strong grower and easy bloomer for me (on the cool side of intermediate in a terrarium). It blooms sequentially, one bloom at a time on each inflorescence.
There is a more typical form with a bright red lip. I got this one from Lynn O'Schaughessy originally.
