Barkeria
Barkeria, abbreviated Bark in horticultural trade, is a genus of orchids. It consists of about 17 currently recognized (May 2014) species native to Mexico and Central America. This genus was once considered part of Epidendrum. Type species is Barkeria elegans; this is now considered a synonym of B. uniflora yet retains its status as type per ICN.
These are deciduous orchids, which drop their leaves in early winter. They are found in dry scrub areas of Mesoamerica at intermediate elevations.
