Common Name Steinbuch's Pleurothallis [Edith Steinbuch, Venezuelan Co-collector of species]

Flower Size .2" [5mm]

Found in Bolivar department of Venezuela at elevations around 1000 meters as a mini-miniature sized, warm to cool growing, caespitose epiphyte with ascending ramicauls enveloped by a thin, tubular sheath and carrying a single, apical, suberect, coriaceous, broadly elliptical, often overlapping, subacute to obtuse, cuneate below into the subpetiolate base leaf that blooms in the winter on a loose, slender, .12 to .36" [3 to 9 mm] long, successively 2 to 3 flowered inflorescence with just shorter than the ovary floral bracts.

"This small species is closely related to P barbulata but is distinguished by small, broadly elliptical, to round, more or less overlapping leaves that are borne by a shortly repent rhizome and that are surpassed by a distantly and successively two to three flowered raceme. The dorsal sepal is free, narrow and acute, the synsepal is shortly bifid, the petals are oblong, obtuse and glabrous and the lip is narrowly oblong, narrowly obtuse or subacute, minutely ciliate and shallowly channeled centrally. The base is bilobulate."
