Characteristics

Plant acaulescent, flowering to over 1 m long, with a crateriform, 40-60 cm tall rosette of many somewhat lustrous green leaves. Leaves thin-coriaceous, 35-70 cm long, exceeded by the scape, pale-green, often suffused with pale-lilac below; sheaths distinct, tapering into the blade, (lance-) oblong, somewhat inflated, 10.5-24.5 x 5.8-7.5 cm, with broad membranaceous margins, subdensely pale-brown appressed-lepidote on both sides, less so toward the apex, pale-brown to dark castaneous at the base; blades arching, ligulate, 25-56 x 2.8-4.2 cm, rounded then often triangular attenuate and apiculate, sparsely and minutely lepidote outside, subglabrous inside. Inflorescence laxly compound of about 3 racemes or rarely simple; scape erect, (33-)60-75 cm long, 5-6 mm in diam., glabrous, partly exposed; scape bracts erect, chartaceous, the lower ones imbricate, ovate-oblong, the upper ones more ovate, acuminate, exceeding or much shorter than the internodes, subdensely to sparsely punctulate-lepidote, greenish to dull-magenta; axis ample, straight, terete, glabrous; primary bracts as the upper scape bracts, spreading with, and much exceeded by the peduncle; peduncle 6-14 (apical one) cm long, prophyllate and often bearing one or a few remote sterile bracts; racemes slenderly ellipsoid to cylindric, 8.5-20 cm long (apical one always about twice as long as the axillary ones), ca. 3.5 cm wide, obtuse, sublaxly and polystichously 18-45-flowered, densely so toward the apex, with one or a few sterile bracts at apex; floral bracts clasping the flower, thin-coriaceous, with even or faintly veined surface, ovate, 1.2-1.9(-2.3) cm long, just exceeding to much longer than the internodes, much exceeded by the sepals, membranaceous at the margins, obtuse, ecarinate, sparsely and minutely lepidote inside, glabrous outside, pale-green. Flowers spreading, sessile or short pedicellate; receptacle cuneate, angled, ca. 3 mm long; sepals coriaceous, with even surface, slightly asymmetrically obovate-oblong, 1.5-1.8 cm long, with a membranaceous margin at one side, rounded or obtuse, evenly short (3 mm) connate, posterior ones alate-carinate in lower half, minutely appressed-lepidote inside, glabrous outside; petals thin, 2.2-2.5 cm long, white(?), the free lobes (blades) spreading, obovate, ca. 0.7 cm long; stamens slightly shorter than the petals and the pistil, filaments highly adnate to the petaltube, free part dilated and compressed, anthers dorsifixed (between 1/3 and 1/2), 3.5-4 mm long, short free basal lobes and apex apiculate; ovary ovoid, ca. 5 mm long, tapering into the slender style, stigma lobed. Capsule (broadly) cylindric, 2.2-3.2 cm long, much exceeding the sepals, short-beaked; coma red-brown.
