Flower Size 1 1/2" [3.75 cm]

Common Name The Notched Dimerandra

Found from Mexico, Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Guyana, Surinam, French Guiana, Trinidad and Tobago and Brazil in rain forests at elevations of sea level to 800 meters as a medium sized, hot to warm growing epiphyte with cylindric, furrowed stems enveloped by numerous, basally clasping and conduplicate, distichous, articulate, elliptic-lanceolate, coriaceous, apically unequally bilobed leaves that blooms in the summer and fall on a terminal, fasciculate, sessile, 1 to 1 1/4" [2.5 to 3 cm] long, successively flowering, racemose inflorescence.

There is much discussion that all Dimerandra species are this one. This species is often found in conjunction with ants and may benefit from their presence.
