Common Name The Acute Lip Pleurothallis

Flower Size .2" [5 mm]

Found in Choco' department of Colombia at elevations around 1900 meters as a mini-miniature sized, cool growing, caespitose epiphyte with slender, erect to suberect ramicauls with a tight fitting tubular sheath below the middle and another at the base and carrying a single, apical, erect, coriaceous, narrowly ovate, acute, cuneate below into the sessile base leaf that blooms in the summer on a resting on the leaf, arising through a spathe at the base of the leaf, .16" [4 mm] long, successively single flowered inflorescence.

"This species is intermediate between Section Acroniae and Macrophyllae-fasciculatae but the short peduncle and pedicel place it better within Macrophyllae-Fasciculatae. Characterized by the slender ramicauls, spreading, narrowly ovate leaves, successive flowers with a concave, obtuse dorsal sepal and synsepal; elliptical petals nearly as large and a triangular lip with an acute apex."
