Stems 4–6 ft. or more high, simple or branched, glabrous, except some minute bristles in the axils of the leaves and along the rudimentary stipular line. Leaves ascending; petiole 1–4 lin. long; blade 2 1/2–6 in. long, 2–7 lin. broad, broadly linear or linear-lanceolate, tapering to an acute point, acutely narrowed into the petiole, slightly thickened along the margins, quite glabrous. Flowers in pedunculate several-flowered bracteate umbel-like racemes (the axis of the umbel shortly elongating), lateral between the bases of the leaves; peduncles 1 1/2–2 1/2 in. long, glabrous; outer bracts 4–6 lin. long, the succeeding ones gradually smaller, deciduous, glabrous; pedicels 6–12 lin. long, glabrous. Sepals 1 1/2–4 lin. long, varying from ovate-anceolate to linear-lanceolate. Corolla deeply 5-lobed, somewhat reflexed (or, in the dried state, often more or less campanulate), whitish; lobes 4–5 lin. long, bordered inside with woolly hairs, glabrous on the back. Coronal-lobes arising 3/4–1 lin. above the base of the staminal-column, with the tips reaching to its summit, 1 1/4–1 1/2 lin. long and about 1 lin. broad, complicate, obliquely deltoid-ovate viewed sideways, with the dorsal side much the shorter, the inflexed sides produced into acute or linear-acuminate teeth sometimes in-curved over the tips of the anthers and sometimes only level; 5 small teeth alternate with the lobes at their base are more or less incurved and hidden under the basal parts of the anther-wings. Staminal-column 2–2 1/2 lin. long; anther-appendages roundish-ovate, obtuse, inflexed over the apex of the style. Pollen-masses (excluding the caudicles) 2/5– 1/2 lin. long, 1/6 lin. broad, turgid. Follicles solitary (always?), 2–2 1/2 in. long, 4–5 lin. thick, lanceolate, acute or tapering into a beak, glabrous. Seeds (not seen mature), ovoid, narrowed into a beak, channelled on one side, very turgid on the other, smooth or nearly so, crowned with a tuft of hairs.
