Common Name Mahecha's Pleurothallis [Colombian Gilberto Emilio Mahecha Forest Engineer2021]
Flower Size .4" [1 cm]
Found in Antioquia, Cundinamarca and Caldas departments of Colombia at elevations of 2700 to 2800 meters as a small sized, cold growing, caespitose epiphyte with erect, slender, yellowish green, bowed ramicauls provided with a tubular, truncate, whitish to brown, papyraceous sheath and carrying a single, apical, borne transversally at the apex of the ramicaul, parallel to the stem, strongly coriaceous, rigid, horizontal to acutely deflexed, rigid, oblong-lanceolate, acute to acuminate, concave, with involute margins, deeply cordate, forming two slightly imbricate lobes below into the sessile base leaf that blooms in the winter on a descending, arising from a prominent, reclining, brown, papyraceous spathe that is fibrous when mature, eventually disintegrating with age, single flowered inflorescence.
"Part of the Pleurothallis cardiostola/Pleurothallis lilijae complex. Pleurothallis mahechae is most similar to P. lanigera but is easily distinguished by the leaf shape (oblong-lanceolate in P. mahechae versus broadly ovate in P. lanigera); leaf base (cordate, with basal lobes deeply reflexed in P. mahechae versus cordate, with basal lobes flat or occasionally slightly reflexed in P. lanigera); the position of the flower (resupinate in P. mahechae versus predominantly non-resupinate in P. lanigera); and the lip morphology (planar to convex, with two V-shaped calli in P. mahechae versus concave with thickened lateral edges in P. lanigera)."
