Common Name or Meaning The Cotyledon-Like Eurystyles
Flower Size .04" [1 mm]
Found in the Mantiqueira Rain Forest Mountains of Minas Gerais and Sao Paulo State Brazil as well as Costa Rica, Panama, Cundinamarca, Risaralda, Valle de Cauca departments of Colombia, Venezuela, Ecuador and Peru in seasonally dry cloud forests at elevations of 500 to 3150 meters as a mini-miniature sized, warm to cold growing epiphyte with a basal rosette of elliptic, acute, apically marginally minutely hairy leaves that are conduplicate below into a distinct petiole that blooms in the late summer and fall on a short to 1" [2.5 cm] long, pendant inflorescence with a head-like cluster of several [6 to 8] flowers with inflated, pilose floral bracts.
Eurystyles colombiana is often cited as a synonym of E cotyledon but E colombiana differs most in the ciliate leaves, the erect inflorescence, the ciliate-denticulate margins of the floral bracts, the distinctly dorsally serrulate-carinate dorsal sepal, the linear-oblong, obtuse, dorsally serrulate-carinate lateral sepals, the petals that are connivent with the dorsal sepal that are slightly thickened at the obtuse apex, the terminal part of the lip apex sub-orbuicular, papillose-ciliate, the main disc pandurate and the ovary is sessile, ovoid to fusiform and glabrous.
"Similar to Eurystyles auriculata but E cotyledon the lip is linear-oblong to ligulate-subpandurate, the epichile is subquadrate, truncate, with revolute margins and papillate, devoid of any central thickening. E auriculata is characterized by pandurate-obovate lip constricted distinctly near the middle and shallowly toqwards the apex. The apical lip part is promenetly thickened in the center. Both specsies can be recognized by the position of the lip basal auricles which are either parellel in E cotyledon or perpendicular in E auriculata with the lip claw." Szlachetko & Kolanowska 2019
