plant lacking rhizomes, flowering 45–60 cm tall. leaves 28 to 45, densely rosulate, subcoriaceous, forming a narrow funnelform rosette at base; sheath narrowly elliptic, suberect, 6–7.5 × 4–4.5 cm, densely brown-lepidote; blade narrowly triangular, acuminate-caudate, distinctly canaliculate, suberect to spreading at anthesis, 17–25 cm long, 2–2.5 cm wide at base, dark green but color almost completely obscured by a very dense layer of cinereous trichomes mainly abaxially, margins not truncate and less than 0.5 mm thick. inflorescence: peduncle suberect to nearly spreading, 35–40 cm long, 0.5–0.6 cm in diameter, dark-green, glabrous; peduncle bracts the basal ones foliaceous, the upper ones ovate, acute and apiculate, 2.7–3 × ca 2 cm, erect and almost completely enfolding the peduncle, slightly exceeding the internodes, inconspicuously white-lepidote, distinctly nerved-sulcate, dark brown toward the base, paleaceous toward the apex; fertile part simple, suberect-ascending toward the apex, sublinear, 10–15 × ca 2.5 cm, distichously 9- to 11-flowered, rachis ca 6 mm in diameter, stout, flexuous, slightly angled, green, glabrous; floral bracts broadly ovate, acute, 26–30 × ca 23 mm, sparsely and minutely white-lepidote to glabrous, ecarinate, slightly incurved and secund with the flowers, dark purplish-green, strongly sulcate mainly toward the apex in late anthesis, without decurrent auricles at base, about equaling the midpoint of the sepals. flowers 40–45 mm long, anthesis nocturnal, producing an odor somewhat related to garlic, densely arranged and divergent-erect before anthesis, subdensely arranged and distinctly secund at anthesis, pedicel 8–9 mm long, stout; sepals elliptic, emarginate, 24–25 × 13–15 mm, green with purplish margins, glabrous adaxially, very inconspicuously lepidote abaxially, ecarinate, thick near the base; petals obovate, apex broadly emarginate, spreading at anthesis, 37–38 × 17–18 mm, pale yellowish-green, bearing at base 2 slightly asymmetric, subobovate, long acuminate to bidentate, ca 11 × 2.5–3 mm appendages basally adnate to the petals for ca 5 mm, corolla 27–30 mm in diameter. stamens: filament free, slightly complanate, 23–27 × ca 1.5 mm; anther 6– 8 mm long, dorsifixed near the base, base and apex obtuse, 3 of them disposed on the basal portion of the corolla and the other 3 on the lateral side of the corolla at anthesis or 3 of them disposed in opposite sides of the corolla; pollen ellipsoid, sulcate, exine reticulate, lumina broadly rounded, muri narrowed. pistil: stigma tubolaciniate, irregularly and minutely crenulate, green, ca 2 mm in diameter; ovules caudate. fruits unknown.Edited from : Pereira 1971.
