from Icones Hagasater 14 ---







 Epidendrum aura-usecheae belongs to the Secundum Group which is recognized by the caespitose habit, numerous



coriaceous leaves, and generally an elongate peduncle to a pluri-racemose inflorescence, brightly colored flowers generally pollinated by



hummingbirds, and the caudicles of the pollinarium granulose, the tetrads appearing like a loose pile of roof-tiles, without any spathaceous



bracts; and Elongatum Sub-group, recognized by the non-resupinate flowers with a complicated callus. This species is lithophytic with



yellow flowers, the margins of the lip deeply fimbriate with the fimbria bent in all directions, giving an impression of total disorder; the



column wings are prominent, bent upwards and apically truncate, the margin irregularly dentate. It is color-wise very similar to Epidendrum



xanthinum, described from Minas Geraes, Brazil, which has the margins of the larger lip (7-8 x 9-10 mm), spreading flat, and deeply dentate.



Epidendrum melinanthum Schltr. described from the Valle del Cauca has a much simpler callus formed by 3 tubercles, the lip is T shaped,



with a deeply dentate margin, and the mid-lobe bifid, into two square, somewhat divergent lobes with a mucro in the sinus. The more



common species in the area north of Bogotá is the purple-pink Epidendrum arachnoglossum Rchb.f. Epidendrum fimbria Rchb.f. has orange



colored flowers, shorter leaves, ca. 3.5-7 cm long, the lateral lobes of the lip are semi-ovate with the margin lacerate, and the mid-lobe is



cuneate with the dentate.
