Common Name or Meaning Folsom's Pleurothallis [American Orchid Researcher and collector of the type current]
Flower Size .2" [ 5 mm]
Found in Chiriqui province of Panama at elevations of 1400 to 1700 meters as a miniature to small sized, cool growing, caespitose epiphyte with stout, erect ramicauls enveloped by a tubular, bract in the lower third and 2 to 3 others at the base carrying a single, spreading, coriaceous, ovate, obtuse, acuminate, sessile, deeply cordate, basal lobes overlapping base leaf that blooms in the later summer, fall and winter on a reclining, all concealed by the broad spathe,fascile of .08 to .12" [2 to 3 mm] long peduncles, simultaneously 2 to 8 single flowered inflorescence with an as long as to just shorter than the pedicel floral bract.
" It is most similar to the sympatric P homalantha, but P folsomii is characterized by a larger habit with stout ramicauls that bear a horizontal, deeply cordate leaf. The larger flowers are borne singly, or in a few-flowered fascicle from a short but large and broad spathe at the base of the leaf. The sepals are obtuse, the dorsal is six-veined, the petals are oblong, and the lip is oblong with the apex rounded. The petals are minutely serrate in Folsom's first collection, but are smooth in subsequent collections, all else being equal." Luer as Acronia folsomii 2005
