plant 1 1/2–2 ft. or more high, branching or occasionally simple, 1–1 1/2 lin. thick, bifariously puberulous; internodes very numerous, mostly 1/6– 1/2 in. long, or some of the upper 3/4–1 in. long; leaves often somewhat crowded, sessile or with petioles up to 1 lin. long, very spreading or ascending, 1/2–1 in. long, 1 1/2–4 lin. broad, often broadest near the apex, spathulate-oblong, oblong or linear-oblong, obtuse or rounded and minutely apiculate at the apex, truncate or subhastate at the base, scabrous-pubescent along the revolute margins, otherwise glabrous; umbels pedunculate, subcorymbose or clustered at the apex of the branches or the lower racemose, 4–8-flowered; peduncles 1/3–1 1/4 in. long, pubescent or subtomentose on one side, as are the unequal 1 1/2–6 lin. long pedicels; bracts 3/4–1 1/2 lin. long, subulate; sepals 1 1/2 lin. long, 1/2 lin. broad, oblong or oblong-lanceolate, acute or subobtuse, slightly puberulous; corolla-lobes ascending, 2–2 1/2 lin. long, 1 1/3–1 1/2 lin. broad, oblong or slightly obovate-oblong, slightly emarginate at the very obtuse apex, concave, glabrous on both sides; corona-lobes 1/2 lin. long, 2/5 lin. broad, much shorter than the staminal column, ovate or ovate-oblong, subtruncate, emarginate or shortly bifid at the apex, with a divided appendage and 2 parallel distant keels placed near the margins and having a short keel on each side extending from the base of the appendage obliquely downwards and to the margin on the inner face; appendage 1/3– 2/3 lin. long, arising near the apex of and more than half as broad as the lobe, much exceeding it and reaching to or slightly exceeding the style-apex, divided to the base into 2 subulate contiguous or slightly divergent segments straight or slightly recurved at the tips; staminal column 1–1 1/4 lin. long; anther-appendages broadly ovate, obtuse, applied to the underside of and not exceeding the rim of the concave or crater-like style-apex. null
