Impatiens sultani, Hook. f. From 12-24 in. high, with stout st. and branches, rather succulent and green, glabrous: lvs. elliptical or lanceolate and narrowed into a petiole about 1 in. long; lower lvs. alternate, upper ones almost whorled: peduncles axillary; fls. rich scarlet in the original form; petals flat; standard obovate- orbicular and retuse; lip less than half length of petals, suddenly narrowed into a slender upwardly curved long spur. Hybrids and sports have given shades from pink to almost purple, and a white variety also exists. Spur is very long and thin. Zanzibar.—Increased by seeds; also by cuttings, which root readily. A greenhouse plant; it also does well as a house plant, blooming almost continuously. var. episcopi, Hort. A perpetual flowering variety with purple-carmine fls. marked brilliant rose.—I. sultani was named by Hooker "in honor of that distinguished potentate, the Sultan of Zanzibar, to whose enlightened and philanthropic rule eastern Africa owes so much."
