DESCRIPTION: Found in Jalisco, Michoacan and Nayarit Mexico on and near the Pacific coast in mangrove swamps, wooded roadsides and barren lava flows as a small sized, hot to warm growing, mule-eared epiphyte or occasional lithophyte on rocks at elevations of sea-level to 1300 meters with small ovoid pseudobulbs partially enveloped below by triangular, leafless sheaths carrying a single, apical, oblong-lanceolate, purplish leaf that is keeled below that blooms in the late spring and summer on an axillary, erect, 18" long, racemose, successively opening inflorescence arising from the base of a newly matured pseudobulb with only a few, waxy, long lived flowers open at a time. This racemose inflorescence can expand over time and new flowers can appear over the blooming period on the old spike.
