Filaments of the upper (oppositipetalous) stamens 1·5-2 mm. long, inserted 1 mm. below the base of corolla-lobes, those of the lower ones (alternipetalous) c. 1 mm. long, inserted c. 1·5 below the sinuses between the corolla-lobes; anthers 1·3-1·4 mm. long, broadly ovate to subcircular, emarginate at the base, apiculate, those of the upper stamens completely exserted, the others included or their apices slightly above the sinuses of the corolla-lobes.
Succulent shrublet, rosettes developing a single, erect stem, up to ± 1.5 m high. Leaves sessile obovate to oblanceolate-oblong, flattened, 80-120 x 30-70 mm, clasping, glabrous, grey-green with red margins. Inflorescence a slender, elongate thyrse with many tight dichasia ending in monochasia; flowers sweet scented. Corolla grey-green covered with thick bloom; tube quadrangular-cylindrical, 12-16 mm long; lobes deep yellow. Flowering time May-Sept.
Perennial herb, up to 1.5 m high; single stemmed from base; glabrous. Leaves sessile; blade obovate to narrowly obovate-oblong, 80-120 x 30-70 mm, apex rounded, base clasping, margins entire, greyish green with red margins. Flowers: inflorescence a slender, elongate thyrse; calyx lobes ovate, 2.5-4.0 mm long; corolla tube 12-16 mm long, greyish green with a bloom, lobes almost square, 2-3 mm long, deep yellow; Feb.-Jul.
Leaves decussate, denser towards the base of the stem, obtuse or rounded at the top, entire, sometimes with pinkish margin, sessile, connate at the base and semi-amplexicaul, slightly decurrent, thick, fleshy, concave on the upper face, somewhat convex on the under one, the lower 7-17·5 x 7-12·5 cm., obovate or obovate-spathulate, the median and the upper ones successively smaller, oblong or spathulate.
Corolla-tube 11·5-15 mm. long and 6-7 mm. in diameter, suburceolate or ovoid-oblong, slightly contracted at the top, terete towards the base, distinctly 4-angular upwards, yellow or glaucous, pale and scarious-papyraceous on drying; corolla-lobes 3·25-5 x 3-4·5 mm., ovate to suborbicular, obtuse or rounded at the top, obsoletely apiculate, golden-yellow on the inner face, reflexed.
Stem single, arising from the rosette of leaves of the previous year, simple, erect, stout, terete, up to 2·5 cm. in diameter at the base and ±1·25 cm. in diameter below the inflorescence, smooth, leafless below at flowering time and marked there with the very close scars of fallen leaves.
Rosettes usually developing only 1 erect stem, up to 1.5 m high. Leaves sessile, obovate to oblanceolate-oblong, greyish green with red margins. Inflorescence an elongate thyrse. Corolla tube 12-16(-20) mm long. Flowers grey-green and deep yellow.
