Common Name The Tiny Lip Pleurothallis

Flower Size .24” [6 mm]

Found in Zamora Chinchipe province of Ecuador on the eastern slope of the Andes in cloud forests at elevations of 1000 to 1400 meters as a mini-miniature sized, cool growing epiphyte with suberect, spreading, slender, terete ramicauls enveloped by 3, thin, papery, tubular sheaths and carrying a single, apical, coriaceous, horizontal, ovate, acute, shallowly cordate into the sessile base leaf that blooms in the fall on a short, arising through a reclining spathe, .24 to .312” [6.0–7.8 mm] long, a fascicle, successivly single flowered inflorescence carrying resupinate flowers.

”In subsection Macrophyllae-Fasciculatae, the most morphologically similar species is Pleurothallis erythrium Luer. The new species is easily distinguished from P. erythrium by the lip (ovate-triangular, approximately 50% the length of the synsepal, with distinct glenion in P. erythrium versus highly reduced, not projecting beyond the column, glenion apparently absent and apical, papilla-lined cavity in P. minutilabia) and the surface of the petals and sepals (hirsute in P. minutilabia versus glabrous in P. erythrium).” Wilson, Tobar & Perez 2018
