Common Name The Posada's Stelis [Named for Lijia, Jaime and Juan Filipe Posada in whose greenhouse at Colomborquídeas this species was being cultivated.]

Flower Size .4" [1 cm]

P>Found in Colombia without locational data as a small sized, cool to cold growing, densely caespitose epiphyte with stout, erect, ramicauls enveloped by a loose tubular sheath on the upper half and another loose, tubular sheath in the lower half and another at the base and carrying a single, apical, erect, coriaceous, elliptical, obtuse, cuneate below into the petiolate base leaf that blooms in the fall on a single, erect, arising through a spathe from a node below the abscission layer, peduncle 2" [5 cm] long, rachis 10" [25 cm] long, erect, distichous, lax below, congested above, simultaneously many flowered inflorescence and carrying light green, non-resupinate flowers.

"This large, robust, handsome species is distinguished by stout ramicauls clad in loose, tubular sheaths, and an elliptical leaf abruptly contracted into a petiole. Numerous, relatively large, non-resupinate flowers are produced with oblique floral bracts in a long raceme that becomes crowded near the middle before dissipating at the tip. The sepals broadly ovate, pubescent and multiveined; the semilunate petals are concave below a broad, thick, rounded apical margin; the lip is type A with a narrowly obtuse apex and a narrow glenion."
