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, 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.
E 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.
Synonyms Eurystyles auriculata Schltr. 1923; Eurystyles paranaensis (Schltr.) Schltr. 1926; Stenoptera roehlii Schnee 1946; Trachelosiphon paranaense Schltr. 1920
