Common Name The Erose Pleurothallis [refers to the leaf margins]

Flower Size .4" [1 cm]

Found in the Dominican Republic and Haiti at elevations around 1000 to 1500 meters as a mini-miniature sized, cool growing, caespitose epiphyte with slender ramicauls enveloped by 3 tubular sheaths with the uppermost longest and carrying a single, erect in relation to the ramicaul, coriaceous, minutely crenulate margined, elliptical, acute, cuneate below into the sessile base leaf that blooms in the fall, winter and spring on an erect, arising through a spathe at the leaf base, loose, flexuous, disitchous, 1.2 to 1.8" [3 to 4.5 cm] long including the .6 to .8" [1.5 to 2 cm] long slender peduncle, simultaneously few flowered inflorescence with , as long to longer than the ovary oblique, dilated floral bracts.

"I suspect that the plants are pendent growing. The leaves are elliptical and sessile with minutely crenulate margins. The loosely few flowered inflorescence is about twice as long and flexuous. Isuspect that it is pendent, as is the case in many species which would place the lip lowermost in the flower. The sepals are more than .4" [1 cm] long and half as wide . The dorsal sepal is narrowly linear, the laterals are connate into an oblong, bispiculate lamina with a longitudinally convex center half that is concave externally between carinae. The petals are narrowly acute and minutely serrate. The lip is small and deeply fringed above a broad claw." Luer 2000
