Barkeria lindleyana Bateman ex. Lindl.
Epidendrum lindleyanum (1862)
Barkeria lindleyana var. centerae (1890)
An erect, deciduous herb with an epiphytic growth habit that grows to 75 cm in height, although some specimens in nature have been observed as tall as 165 cm. Roots: thickened, terete, long, fleshy, white in color with green tips. Stems: grayish-white, thickened, slightly compressed laterally, 10-25 cm. in length. Older stems are covered with scarious, papery bracts. Leaves: 8-14 ovate oblong to lanceolate, acute, distichous, coriaceous to subsucculent present only on the newly developing growth and appressed to the stem via an articulated joint. Inflorescence: terminal, erect, raceme (very rarely a compound raceme), from the new growth, on an elongated peduncle covered by tubular bracts (scarious at anthesis) 15-50 cm. in length. Flowers: Attractive, weakly fragrant, 4.5-7.5 cm diameter spread, intense pinkish-purple in color. The lip has a white or yellowish-white circle on the disc and darker blotch at the apex. The sepals are subequal, lanceolate to elliptic-lanceolate, acute, reflexed and slightly convex. Petals are nearly twice the width of the sepals, spreading, flat, broadly rhombic, acute to subacute. The petals are rotated forward nearly 90° degrees so as to present the adaxially sulcate surface to the pollinator. The lip is entire, free of the column except basally, ovate to subcuadrate or subcuadrate-obovate, margins faintly undulating, erect at the base clasping the column, flat to convex and slightly reflexed at the apex so as to give the appearance of a raised tip. The dorsal surface of the subtrigonous, somewhat dorsiventrally compressed, straight, spatulate column is magenta and suffused with dark purplish-black spots mainly over the greenish-white, membranaceous column wings. The column has two prominent teeth on either side of the clinandrium. The callus is greenish-white or creamy-white with purple longitudinal striping with two oblong, laminar keels that delimit a fovea, which converges into three (rarely five), raised longitudinal keels, becoming more elevated at the terminus and with the central one reaching almost the apex. The keels are same color as the disc but sometimes with spotting or longitudinal lines over them at the point that the color transitions from white to pink
