Herbs, perennial, 4–10 dm, glabrous or hairy, hairs simple and glandular; rhizomatous, rhizomes horizontal, woody. Stems 1–5, proximal to inflorescences, erect to ascending, usually red when young, usually simple. Leaves persistent, basal and cauline, ternate; stipules depressed-ovate or linear, margins serrate, doubly serrate, shallowly laciniate, incised, lobed, or dissected; petiole present or absent; blade trullate to widely trullate, 3–9 cm, herbaceous, leaflets 3, lanceolate to ovate-oblong, 4–8 cm, margins flat, incised, doubly serrate, teeth gland-tipped, variably glandular and hairy. Inflorescences terminal, 3 (–9) -flowered, loose, leafy panicles; bracts present; bracteoles absent. Pedicels present, 1–7 on each branch. Flowers 10–20 mm diam.; hypanthium often red or purple, 4.5–8 mm, glabrous; sepals 5, erect, triangular-ovate; petals 5, white to pale rose, linear-lanceolate, unequal; stamens 20 (in 3 whorls), shorter than petals; styles filiform, glabrous, stigmas capitate. Fruits aggregated follicles, 5 (1–5 maturing), broadly ovoid to broadly elliptic-ovoid, slightly flattened, 4.5–8 mm, strigose to villous-strigose, glabrous, or glabrate, partially dehiscent abaxially and partially adaxially; hypanthium persistent; sepals persistent, erect to loose spreading at apices. Seeds 2 per follicle, light-brown to reddish, longitudinally rugulose, glabrous. x = 9.

Discussion

Species 2 (2 in the flora).

Porteranthus Britton, a superfluous and illegitimate name, was proposed by N. L. Britton in 1894 as a substitute for Gillenia because the similar name Gillena had been used by Adanson in 1763. Both names refer to Arnold Gillen. A proposal to conserve Gillenia (D. R. Hunt 1982) was opposed by K. R. Robertson (1983); a vote (E. G. Voss 1986) indicated that the two names are not confusable.
