Common Name The Thin Pleurothallis

Flower Size 1/4" [.6 cm]

Found in Colombia and Azuay, Chimborazo and Napo provinces of Ecuador in lower cloud forests on mossy trees including orange trees at elevations of 500 to 1800 meters as a small sized, warm to cool growing, caespitose epiphytic or lithophytic species with slender, erect, ramicauls enveloped basally by 3 tubular, close sheaths and carrying a single, apical, lanceolate, truncate, acute, abruptly narrows below into the base leaf that blooms spring and summer on a subsessile, arising from a small spathe, .8" [2 cm] long, several successively single flowered inflorescence with a thin, tubular, leass than half as long as the pedicel floral bract.

"This small species is similar to and sympatric with Pleurothallis ensata . Although flowering plants are readily distinguishable, descriptions and dried specimens appear deceptively alike. Both species have slender secon-dary stems terminated by an erect, very narrowly ovate leaf. The smaller flowers of P. ensata are produced singly and successively; those of P. stenota are produced several at a time. The sepals and petals of the latter are longer and proportionately narrower. The petals of the former are short and thick. The flowers of P. stenota spread widely, the narrow dorsal sepal and the synsepal pointing 1800 from each other producing a slender, vertical flower .8" [2 cm] long."

"Distinguished by the slender ramicauls and erect, narrowly ovate leaves that are shallowly cordate at the base.. Several, light orange or tan flowers re often produced simultaneously. The dorasal sepal, synsepal and the petals are narrowly ovate and the lip is oblong with a rounded apex." Luer 2005
