Information leaves (unknown); corolla thrice or four times as long as the sharply 4-cleft calyx, its segments broadly oblong, very blunt or truncate; stamens as long as the tube of the corolla. Of this very remarkable plant a portion of a denuded branch, and part of a dense, probably thyrsoid, inflorescence exist in Herb. Sonder. The internodes are scarcely an inch long, and there are 4 cicatrices, indicating whorled leaves, at each node. Calyx 3 lines long. Corolla uncial, bright red, its lobes almost square, 2 1/2 lines long.

Information Sparse glabrous shrublets up to 2 m high, with one or few erect terete branches, often growing in dense stands; roots not thickened. Leaves ternate, to apparently op­posite or alternate, sessile, glabrous, terete, (20-)25-80(-120) x (2-)3-5 mm in diam. with 5-8 apical teeth producing pseudobul­bils in their axils, more or less grooved above, grey-green and with darker spots. In­florescence a rounded thyrse with several closely clustered dichasia. Calyx with lobes triangular-lanceolate, 5-10 mm long. Co­rolla pale orange to deep magenta; tube widened in middle and at throat, 25-33 mm long, lobes oblong-obovate, 8-12 x 6-9 mm. Anthers 2-2,5 mm long. Squamae ob­long to almost square, 1,3-2 mm long, rounded at apex. Seeds 2-2,5 mm long. Fig. 10.

Information A completely glabrous perennial succulent. Stem 0·20–1·20 m. high, erect, simple, terete, with sterile shoots at the base. Leaves ternate or alternate in the adult plant, opposite in the first nodes of the young shoots, ± caducous at flowering time, 1·5–13 cm. long and 2–6 mm. in diameter, terete, slightly canaliculate on the upper face, with 2–9 small apical teeth producing pseudbulbils in their axils, sessile, usually straight, erect to spreading, fleshy, greyish- or dull-green, spotted with dark green or red. Flowers in cymes forming a terminal, rather dense corymbose inflorescence up to 10–15 cm. in diameter; pedicels 6–20 mm. long. Calyx equalling 1/4–1/3 of corolla, campanulate, green striped with red; tube 2·5–5 mm. long; lobes 5·8–7·7 x 3·7–5·7 mm., lanceolate, very acute. Corolla reddish–orange or reddish–ochre below, pale yellow suffused with red upwards; tube 22–5·35 mm. long, rather constricted just above the carpels, subfunnel–shaped–campanulate upwards; lobes 7–10·2 x 7–9·8 mm., obovate, obtuse or truncate, apiculate, spreading. Stamens attaining the top of corolla; filaments inserted below the middle of the corolla–tube; anthers 1–2 x 1–1·7 mm., broadly ovate. Carpels c. 6·15 mm. long, adnate for c. 1·65 mm.; styles 19·5 mm. long. Scales 0·7–1·6 x 0·85–1·4 mm., semicircular to trapeziform. Seeds 0·6 x 0·3 mm., obovoid.

Information Herbs, monocarpic, (sometimes suckering at base), pale green mottled with violet-brown, glaucous. Stems simple, terete, 5–20 dm × 0.5–1 cm. Leaves mostly in 3s, opposite or whorled, evenly spaced, simple; petiole and blade indistinguishable, reddish green to gray-green with reddish brown spots, narrowly oblong, subcylindric, grooved adaxially, 3–15 cm × 3–6 mm, margins entire except for 3–9 conic teeth at apex, apex blunt, surfaces not glaucous; bulbils borne between teeth, spurs spoon-shaped. Cymes mostly dense, corymbiform, 0.5–2 dm diam.; branches to 3 cm. Pedicels 5–30 mm. Flowers: calyx pale green, not inflated, 8–16 mm, tube 3–6 mm, lobes triangular, 5–10 mm, longer than tube, apex acuminate; corolla orange to scarlet, 25–40 mm, not contracted basally, lobes obovate, 6–12 mm, apex rounded or apiculate. 2n = 68.
