Common Name The Thread-Shaped Platystele [refers to the petals]
Flower Size .16" [4 mm]
Found in Narino department of Colombia in wet forests without locational data as a mini-miniature sized epiphyte with erect, slender ramicauls enveloped by 2 to 3, thin, ribbed, imbricating sheaths and carrying a single, apical, erect, coriaceous, elliptical-obovate, subacute, narrowly cuneate below into the slender petiolate base leaf that blooms in the summer on a erect, weak, arising laterally on the ramicaul, peduncle filiform, .8 to 1" [2 to 2.5 cm] long, rachis distantly distichous, 1.4 to 1.6" [3.5 to 4 cm] long, successively single, several flowered inflorescence with a thin, much shorter than the pedicel floral bract.
"Most similar to Platystele acutilingua as both have very small, obtuse, concave sepals and filiform petals. The lip of Platystele acutilingua is exceedingly long-atttenuate, much longer than the sepals, while that of P filamentosa is larger than the sepals but subacute and convex." Luer 1990
