Common Name The Gradually Tapering Point Pleurothallis
Flower Size .8" [2 cm]
Found in Colombia, Venezuela, Ecuador, Peru and Bolivia at elevations of [500] 2000 to 3200 meters as a miniature to small sized, cool to cold growing epiphyte with clustered, erect to ascending ramicauls enveloped basally by 2 to 5 tubular sheaths and carrying a single, apical, erect, coriaceous, oblong, oblong-elliptic to oblong-oblanceolate, rounded to acute to apiculate, cuneate below into the short, petiolate base leaf that blooms on 1 to 2, erect to suberect, subdensely many flowered, 2.8 to 9.2" [7 to 23 cm] long, racemose inflorescence arising through a spathe.
"Even though the plant is variable it is always distinguished by the ramicuals more or less equal to the elliptical to narrowly elliptical, obtuse leaf length and elongated racemes of nearly simultaneous flowers. P tenuifolia differs only in the narrow leaves and P angustipetala is only slightly smaller. The leaves of P stenophylla and P lagarophyta seem sufficiently distinct but the flowers are very similar. P dimidia is a small very similar taxon and has delicate, smaller flowers is also very similar.
