A subcaespitose, slender, deciduous herb with an epiphytic or lithophytic growth habit that grows to 75 cm. Roots: thickened, flattened, long, fleshy, gray in color with green tips. Stems: grayish-white, thickened, slightly compressed laterally with 3-9 internodes, 3-22 cm. in length. Older stems are covered with scarious, papery bracts. Leaves: 3-7, narrowly-elliptic to elliptic-lanceolate, acute to obtuse, dorsally carinate, distichous, reddish-green in coloration, coriaceous to subsucculent, present only on the newly developing growth and appressed to the stem via an articulated joint. Inflorescence: terminal, sublax, simple raceme with 3-30 flowers, from the new growth, on an elongated peduncle covered by tubular bracts (scarious at anthesis) 8-60 cm. in length. Flowers: Attractive, inodorous, 3.2-4.0 cm diameter spread, most commonly seen as intense magenta but also lilac-purple or pink-purple. The dorsal sepal is erect, narrowly-elliptic to oblanceolate, acute to subapiculate, flat to slightly concave and sometimes carinate at the apex. Lateral sepals are descending to reflexed, narrowly-elliptic to lanceolate, apiculate, flat to slightly concave, suboblique and with prominent carinate ridges at the apex. Petals are extended, broadly-elliptic to ovate, slightly concave, acute to abruptly acuminate, basally unguiculate, and spreading in a plane at 180° but perpendicular to the column. The lip is concolorous except for the presence of 3-5 brightly colored yellow keels, entire, ovate, abruptly acute to shortly acuminate, basally unguiculate and adnate to the entire column. The exterior keels are thickened and raised as they join with the column to form a v-shaped callus in the center of the disc. The central keel is more prominent and twice the length of the external ones. The dorsal surface of the straight, clavate column is creamy-white and blushed with pink apically. The column is subtrigonous in cross-section with rounded wings, somewhat compressed dorsiventrally, and ventrally sulcate so as to form a dry cuniculus with the lip.
