Common Name The Thorny Pleurothallis [Refers to the spiny seed pods]

Flower Size 1/4" [5 to 8 mm]

Found in Mexico, Guatemala, Belize, Nicaragua, Costa Rica, Panama, Dominican Republic, Haiti, Cuba, Jamaica and Surinam as a miniature sized, hot to cool growing densly caespitose, unifoliate epiphytic species found at altitudes of 300 to 1300 meters in dense, wet, evergreen or deciduous forests growing on oaks in open fields that blooms in the late summer and fall on an apical, short to 1/4", few [to 4], succesively flowered, racemose, inflorescence that holds the flowers close to the base of the subcoriaceous, elliptic-oblanceolate, apiculate, gradually narrowing below into the petiolate base leaf and subtended by a very short ramicaul enveloped basally by 2 to 3 tubular sheaths.

The flower can have a cockleshell burr-like appendage at it's base, this being the forming seed pod. After the flower has disappeared the seed pod matures and turns dark bluegreen.

Give this species hot to cool temperatures, mounted or potted in a well draining medium, year round water and moderate to heavy shade.
