Full Shade Cold LATE Summer EARLY fall

Common Name The Little Concave Lepanthes [refers to the concave leaf]

Flower Size .24" [6 mm]

Found in Zamora-Chinchipe province of Ecuador at elevations around 2500 meters as a mini-miniature sized, cold growing, caespitose epiphyte with relatively stout, erect ramicauls enveloped by 7 to 8, microscopically ciliate lepanthiform sheaths and carrying a single, apical, suberect, thickly coriaceous, broadly elliptical, concave beneath, apex obtuse, shortly acuminate, cuneate below into the petiolate base leaf that blooms in the late summer and early fall on an erect, peduncle filiform, to .2 to .24" [5 to 6 mm] long, rachis to .08 to .12" [2 to 3 mm] long, congested, successively single, few flowered inflorescence with shorter than the pedicel floral bracts.

"This little species from southeastern Ecuador is distinguished by a very short, successively few-flowered raceme that is protected within the undersurface of a suberect, concave, elliptical leaf. The sepals are minutely denticulate and acuminate into setiform tails; the lobes of the petals are triangular; and the blades of the lip are convex with rounded ends. The tip of the delicately ciliated appendix is like a single hair." Luer & Hirtz 2009
