Common Name The Compressed Stem Pleurothallis

Flower Size .1" [2mm]

Found in Haiti and the Dominican Republic as a mini-miniature sized, warm to cool growing, caespitose epiphtye with compressed-alate, erect ascendent ramicauls enveloped by 2 sheaths and carrying a single, apical, fleshy, obovate to elliptic, emarginate, tridenticulate leaf that blooms in the winter on to 3, arising through a spathe, flexuous, distichously to 8 flowered, racemose inflorescence with infundibular, acute, the outer half hyaline becoming dark and wrinkled, longer than the ovary floral bracts.

"The ramicauls are compressed and bear thickly coriaceous, sessile leaves, the flowers are borne simultaneously in distichous racemes that exceeds the leaf. The hyaline, outer halves of the floral bracts become dark and crinkly, imparting a distinctive appearance. The short pedicels are contained within the floral bracts. The ovary is short, broad and densely villous. The fleshy, minutely spotted sepals are cellular papillose and carinate crested. The petals are equally spotted, acute, and entire. The lip is typical for the subgenus." Luer 2004
