Plants rhizomatous or stoloniferous. Stems decumbent or ascending to erect, glabrous proximally, stipitate-glandular distally. Leaf blades elliptic-lanceolate to oblanceolate, base acuminate, apex acuminate. Inflorescences pedunculate, branches stipitate-glandular. Pedicels present, stipitate-glandular. Flowers: hypanthium stipitate-glandular; sepals green or reddish, triangular to narrowly triangular; petals inconspicuous, white or greenish white; filaments white, yellow, or pink, glabrous; anthers yellow or pink. Seeds minutely tuberculate. x = 8 or 9.
Herbs perennial, erect, fibrous rooted. Stems terete, glabrous proximally to finely pubescent and widely branched distally. Leaves alternate, shortly petiolate; leaf blade lanceolate or narrowly so, thin, apex long acuminate. Flowers numerous, arranged in terminal and axillary, scorpioid (or corymblike) cymes, bisexual, yellow-green, small. Sepals 5(-8). Petals 5(-8) or absent. Stamens 10(-16), in 2 whorls. Carpels 5(-8), connate near base; ovules many; styles short. Capsule 5(-8)-lobed; carpels rostrate at apex. Seeds many, small.
"Fls perfect; sep 5(–7); pet small or more often wanting; stamens 10; carpels 5(–7), united nearly to the middle, abruptly narrowed to the short styles, divergent at maturity, forming an angularly 5(–7)-lobed, 5(–7)-locular capsule with horn-shaped lobes, eventually opening by abscission of the lobes; each carpel with a pluriovulate ventral (marginal) placenta just above the united part of the ovary; perennial rhizomatous herbs with erect stems, alternate, serrulate lvs, and a terminal 2–4-branched cyme of secund greenish fls. Sometimes referred to the Crassulaceae. 3, e. N. Amer., e. Asia."
