Found in Alajuela province of Costa Rica at elevations around 1500 to 2000 meters as a small sized, cool growing epiphyte with slender, erect to suberect ramicauls enveloped by a close, tubular sheath in the upper third, and a few others at the base and carrying a single, apical, horizontal to subhorizontal, coriaceous, narrowly ovate to acuminate, acute, cordate below into the sessile base leaf that blooms in the fall and winter on a fascile of 1 to 5, .28 to .4" [7 to 10 mm] long peduncle, successively single, few flowered inflorescence arising and concealed within a spathe at the apex of the ramicaul with a tubular floral bract.
"Pleurothallis silvae-pacis is superficially similar to P. wigginsii C. Schweinf. described from the highlands of north-central Andes in Ecuador. The new species can be distinguished by the longer leaves, the shorter inflorescence, the rose-colored flowers, the one-veined petals, and much shorter, ovate-triangular lip (Luer 1998). Pleurothallis imitor Luer from Costa Rica is also somewhat similar, particularly in plant habit and dimensions of the inflorescence, however, the inflorescence is said to be a two-flowered raceme, the flowers of that species are yellow, the dorsal sepal is erect and flat, and smaller than the synsepal, and the petals have entire margins (Luer 1998). The inflorescence, flower disposition and pollinaria structure suggest affinity with Pleurothallis eumecocaulon Schltr., a species allocated to genus Ancipitia Luer (Luer 1989; 2004
