Found in Risaralda department of Colombia at elevations of 1200 to 1500 meters as a mini-miniature sized, cool growing epiphyte with erect ramicauls enveloped by 2 thin, imbricating sheaths and carrying a single, apical, erect, coriaceous, elliptical, subacute, gradually narrowing below into the shortly petiolate base leaf and blooms in the winter and spring on a suberect, loose, successively few flowered, 1.2" [3 cm] long including the .4" [1 cm] long peduncle, racemose inflorescence arising from low on the ramicaul and has thin, shorter than teh pedicel floral bracts.

"The flowers are lareg for the small size of the plant. The sepals are long-caudate and minutely ciliate. The lip is elliptical and obtuse. P posadarum is closely related to P microglossa but the floral parts of the later are only half as long and the tiny lip is acute. Also related to P caudatisepala but the seplas and petals of the later are narrow and the li pis acute." Luer 1990
