Common Name The Little Beard Pleurothallis
Flower Size .2" [5 mm]
Found in Zamora Chinchipe province of Ecuador in cloud forests at elevations around 2700 as a mini-miniature sized, cold growing, ascending epiphyte with slender, ascending ramicauls enveloped by 1 to 2 loose, tubular sheaths and carying a single, apical, erect, coriaceous, narrowly obovate, obtuse to rounded, gradually narrowing below into the subpetiolate base leaf that blooms in the summer on a capillary, lateral, loose, 6 to 10" [15 to 25 cm] long, successively 2 to 3 flowered inflorescence with an oblique, acute, half as long as the pedicel floral bract.
"This uncommon, tiny species is closely allied to the frequent P. schizopogon, and it can occur in the same locality. Because P. schizopogon is variable in size, this species was at first thought to be merely a small form, but in retrospect the two taxa appear distinct. Except for size, the floral morphology of the two are similar. The sepals of vegetatively larger P. schizopogon are more than .8" [two centimeters] long, while the sepals of the small P. pogonion do not surpass .4" [one centimeter]. The lateral sepals vary from sparsely to densely spiculate." Luer 1994
