EARLY

Common Name Karl's Pleurothallis [Gehrhard Karl Discoverer of species current]

Flower Size .2" [5mm]

Found in Rio de Janiero and Rio Grande Do Sol states of Brazil at elevations around 900 to 1600 meters as a mini-miniature sized, warm to cool growing, repent-ascending epiphyte with erect to suberect ramicauls enveloped basally by 1 to 2, tubular, glabrous, evanescent sheaths and carrying a single, apical, erect, coriaceous, broadly elliptical, obtuse, obscurely emarginate, basally rounded, sessile leaf that blooms in the fall and early winter on a racemose, .15" [3 mm] long, successively few [4] flowered infloresence with as long as to a bit longer than the ovary floral bract.

"Small, broadly elliptical, overlapping leaves are produced by short ramicauls along a creeping rhizome. Slender roots produce capillary, branching roots. A single, dark purple floweis produced successively in an abbreviated, few flowered raceme from the base of the leaf. The sepals are fleshy and glabrous, the dorsal sepal is narrowly ovate and the lateral sepals are falcate and connate near the middle. The petals are narrowly elliptical. The lip is thickly three lobed and diffusely, minutely papillose with incurved lateral lobes occupying the basal half. A row of 3 to 4 [if the center callus is divided in two] small, erect, fingerlike calli stand along the basal margin above a short claw." Luer 2007
