Umbels pedunculate, 5–7-flowered, lateral at the nodes; peduncles 1/2–1 1/4 in. long, puberulous; pedicels 1/2–1 in. long, puberulous. Sepals 2–3 lin. long, 3/4–1 lin. broad, lanceolate, acuminate. Corolla about 1 in. in diam., rotate, 5-lobed nearly to the base; lobes elliptic-lanceolate, acute, purplish outside, pale greenish within. Coronal-lobes arising much above the base of the staminal-column and reaching to its top, complicate, oblong in side view, truncate at the base and apex, with horizontally reflexed teeth from the apices of the inflexed sides, half as long as the upper margin of the lobe, no tooth within.
