Common Name Sorg's Scaphosepalum

Found in western Ecuador in wet montane forests at elevations around 1800 meters as a small sized, cool growing, casespitose epiphyte with erect, slender ramicauls enveloped by 3, tubular, papery sheaths and carrying a single, apical, erect, thinly coriaceous, elliptical, acute, slightly kinked, slightly folded, narrowing beow into the petiolate base leaf that bloooms in the late spring on an erect, arising close to midway on the ramicaul, more or less horizontal, smooth, to 1.46" [3.6 cm] long, provided with 4 to 5, acute thin, skined bracts, successively single, 1 to 2 flowered inflorescence with narrow, acute, bag-shaped, longer than the pedicel floral bract.

"Scaphosepalum sorgii is similar to Scaphosepalum dodsonii , and to Scaphosepalum rapax , but differs by the differently shaped lip, by the bent, purple column (almost 90°), by the oblong shaped synsepals by S. dodsonii; rather orbicular by S. rapax; ovoid by S sorgii; as well as by the smaller dorsal sepals .3" (7.5 mm long) by S dodsonii and S rapax ) as opposed to .213" (5.3 mm) by S. sorgii, by the differently shaped »cushions«, which are narrowly triangular in S. rapax and pointed triangular in S. dodsonii, but right-angled triangular with rounded corners in S sorgii."
