plant epiphytic, propagating by slender stolons 5–10 x 0.2 cm. leaves ca 10, suberect, subcoriaceous, forming at base a narrowly funnelform rosette, the outer ones much narrowed and attenuate-caudate; sheath elliptic, ca 6 x 3 cm, subdensely and minutely white-lepidote, dark purple mainly inside; blade narrowly triangular-lanceolate, 7–19 x 1.3–2 cm, subdensely and minutely white lepidote mainly abaxially, green, entire, apex acuminate and apiculate, apiculous 5–7 mm long. inflorescence: peduncle ca 7 cm long, ca 0.3 cm in diameter, pale green, sparsely white-lanate to glabrescent; peduncle bracts oblong-elliptic to sublinear, acuminate, submembranaceous, pale-green, 30–40 x 5–10 mm, sparsely white-lanate, entire, the upper ones erect and involucrate, about equaling the middle of the sepals; fertile part subellipsoid-capitate, simple, clearly surpassing the leaf-sheaths but not distinctly elevated above the leaf-rosette, ca 40 mm long (excluding the petals), ca 15 mm in diameter; floral bracts narrowly ovate-lanceolate, acuminate-caudate, 10–15 x 3–4 mm, ecarinate, membranaceous, entire, pale-green, sparsely white-lanate, about equaling to slightly exceeding the ovary. flowers ca 6 in number, ca 35 mm long and densely arranged at anthesis, very slightly fragrant, sessile, erect, rachis slightly elongate but not visible, ca 2 mm in diameter, pale green, sparsely white-lanate; sepals strongly asymmetrical, bearing a large rounded lateral wing, membranaceous, 9 x 4–5 mm, apex distinctly mucronulate-caudate and foliaceous, 1.5–2 mm long, connate at base for 3--–4 mm, entire, ecarinate, pale green, sparsely white-lanate at anthesis; petals subspatulate, acute, ca 21 x 5 mm, weakly connate at base for ca 4 mm, spreading-recurved near the apex at anthesis, greenish-white except for the lilac apex, naked but bearing 2 conspicuous longitudinal callosities along the filaments with irregular fingerlike ornamentations. stamens: filament the antepetalous ones adnate to the petals for ca 13 mm, the antesepalous ones adnate to the corolla tube only; anther narrowly elliptic, ca 4 mm long, fixed about 1/3 of its length above the base, base and apex acute. pistil: stigma cylindraceous, ca 3 mm long, ca 1 mm in diameter, conduplicate-spiral, whitish, blades fimbriate; ovary subcylindrical, ca 12 mm long, ca 3 mm in diameter, sparsely white-lanate at anthesis, pale green, epigynous tube narrowly funnelform, ca 5 mm long; placentation apical; ovules subobtuse.Edited from : Leme 1999d.
