LATE EARLY

Common Name The Bearded Lip Lepanthes

Flower Size .12" [3 mm]

Found in Valle de Cauca department of Colombia in humid secondary forests at elevations around 1700 meters as a mini-miniature to miniature sized, cool growing, caespitose epiphyte with suberect, slender ramicauls enveloped by 7 to 10, furrowed lepanthiform sheaths, with a dilated, long-acuminate, ciliated ostia and carrying a single, apical, pendent, erect, thinly coriaceous, ovate, acute, long-acuminate,emarginate apically with an abaxial apiculum in the middle, rounded and contracted below into the cuneate, petiolate base leaf that blooms at least in the late summer and early fall on a filiform peduncle .176 to .28" [4.4 to 7 mm] long, arising on top of the leaf, rachis .48" to .52" [1.26 to 1.3 cm] long, congested, successively single, several flowered inflorescence with acuminate, shorter than the pedicel floral bract.

"Lepanthes pogonochila shares many traits with L. impotens. Both species have caespitose and weak habit with the ramicauls slender to suberect; the leaves ovate, pendent, coriaceous with an apex long acuminate, like most of the species in the series Mucronatae proposed by Luer and Thoerle in 2011. The new species could be distinguished from the latter by its lip’s obovate blades covered by numerous dense, conspicuous bristles at the apex, a pubescent bisegmented appendix with the apical portion subquadrate and bilobed, and the basal portion concave (vs. the lip blades elliptical, with short trichomes, and an appendix reduced to a ciliate margin of the body of the lip) (Luer and Thoerle, 2012). Finally, the new species is also similar to L. oscillifera , but the apex of the blades are minutely ciliate (vs. covered by numerous dense and conspicuous bristles at the apex), the appendix broadly hinged from the center, flap-like, and the apical portion concave and ciliate with a minutely bilobed apex (vs. appendix with the apical portion subquadrate, bilobed, and the basal portion concave)."
