Common Name Silva's Pleurothallis [J B da Silva Brazilian Collector of the type current]

Flower Size .2" [5 mm]

Found in Amazonas state of Brazil at low elevations as a miniature sized, hot growing epiphyte with ascending-erect, terete ramicauls enveloped by a tubular sheath below the middle and another at the base and carrying a single, apical, erect, semiterete, thickly coriaceous, linear, acute, sessile base leaf that blooms in the later spring on an erect, subtended by a spathe 3-4 mm long, at the base of the leaf, peduncle .4" [1 cm] long, simultaneously 2 flowered inflorescence with a shorter than the ovary floral bract.

"This small species, apparently endemic in the state of Amazonas, is related to others with thick or semiterete leaves. It is characterized by narrow, semiterete leaves borne by nearly equally long ramicauls spaced along a repent rhizome. The raceme of the only specimen seen was simultaneously two-flowered, and borne by a short peduncle. The sepals are not fleshy-carinate as seen in Pleurothallis ochreata and relatives. The petals are oblong and acute. The lip is thick with a pair of calli and a pair of lobes above the base." Luer & Toscano 2002
