Flower Size 2.4" [6 cm]

Found in Goias state and the Distrito Federal of Brazil at elevations of 350 to 1600 meters as a medium to large sized, hot to cool growing epiphyte with cane-like, simple, basally terete, laterally compressed above stems carrying 8 to 18, all along the apical 2/3rds of the stem, coriaceous, narrowly elliptic to lanceolate, acuminate, aristate, slightly carinate leaves that blooms in the later spring and summer on a terminal, pluri-racemose, without a spathe, rachis .4 to .6" [1 to 1.5 cm] long, inconspicuous, provided with 1 to 3, triangular, acute bracts, occasionally producing a plantlet from a node of the peduncle, successively single, 1 to 3 flowered inflorescence with much shorter than the ovary, amplexicaul, triangular, acute floral bracts and carrying resupinate, white to greenish white flowers with a white lip and column.

"Epidendrum taguatingense belongs to the GROUP Nocturnum which is characterized by the sympodial, caespitose plants, cane-like, non-fusiform stems, successive flowers on a short, racemose or pluri-racemose inflorescence, without spathaceous bracts, and large, star-shaped flowers, with similar sepals and petals; the flowers are mostly indistinguishable in shape. The species is recognized by the stems 12.4 to 37.6" [31 to 94 cm] tall, laterally compressed towards the apex, leaves 8 to 18, 3.2 to 6.4" [8 to 16 x 1.2 to3.0 cm], length:width = 4 to 6:1 or more, narrowly elliptic-lanceolate, acuminate, erect, laxly distributed along the apical 2/3 of the stems; ovary 2.4 to 2.8" [60 to 70 mm] long, shorter than the leaves. Epidendrum erectum Brieger & Bicalho, also endemic to the Planalto Central of Brazil in the states of Goiás and Minas Gerais, has laterally compressed stems, 12 to 36" [30 to 90 cm] tall, leaves 1.6 to 4" x .48 to 1" [4 to 10 x 1.2 to 2.5 cm], length:width = 2 to 4:1, erect, densely aggregate along the upper 2/3 of the stems; the ovary generally 1.8 to 2.4" [45 to 60 mm] long, and the capsule centered on the fruit. Epidendrum nocturnum Jacq. is widely distributed from Florida to Brazil, has terete stems, few leaves distributed along the apical 2/3 of the stems, the ovary 2 to 2.8" [50 to 70 mm] long, and the body of the fruit occupying nearly the full length of the capsule. Epidendrum carpophorum Barb. Rodr. is found in Venezuela, the Guianas and southeastern Brazil, has stems ancipitose towards the apex, fewer [4 to 6], longer and wider 3.6 to 5.6" x 1 to 2.4" [9 to 14 x 2.5 to 6.0 cm] leaves, perpendicular to the stem, and a longer ovary, 2 to 4.8" [50 to 120 mm] long."
