Stems probably attaining a height of 2–3 ft., branched at the base. Leaves sessile or subsessile, 3 1/2–6 1/2 in. long, 1–3 1/2 lin. broad, elongate-lanceolate or linear, acuminate, glabrous, pubescent on the revolute margins and midrib. Umbels several, lateral and terminal, about 3-flowered; peduncles 1 1/4–4 in. long, pubescent along one side. Bracts 2–8 lin. long, linear, acuminate, ciliate; pedicels 1 1/4–2 in. long, pubescent along the inner side. Sepals 4 1/2–7 1/2 lin. long, 1 1/2–3 1/2 lin. broad, lanceolate or ovate, acute, more or less pubescent on the back. Corolla rotate, 1 1/2–2 1/4 in. in diam. or rather more; lobes 3/4–1 in. long, 4–4 1/2 lin. broad, oblong, acute, glabrous on both sides. Coronal-lobes arising 1 1/2 lin. above the base of the staminal-column and much overtopping it, 4 1/2–7 1/2 lin. long, complicate in the apical part, solid below, obliquely truncate, with the inflexed margins produced into falcate teeth, curved upwards over the tips of the anthers, no horn within.
