Perennial herb [annual], rhizomed. Leaf: basal, cauline, or both, alternate, 2-ranked, sheaths often overlapping to form pseudostem, blade elliptic, midrib prominent, veins parallel. Inflorescence: raceme [panicle], bracts large [minute], overlapping. Flower: bisexual, bilateral; sepals 3, united, petals 3, united; fertile stamen 1, opposite 2 staminodes fused into a petal-like lip, 2 lateral, petal-like [rudimentary], free staminodes also present [or 0]; ovary inferior, placentas axile, parietal, or ± basal, chambers 3, each many-ovuled. Fruit: capsule [berry]. Seed: arilled.
48 genera, ± 1300 species: pantropical. [Kress et al. 2002 Amer J Bot 89:1682–1696] —Scientific Editor: Thomas J. Rosatti.
Pseudostem 1–2 m. Inflorescence: exserted from tip of pseudostem, dense, cone-like [lax]. Flower: calyx cylindric, 3-toothed or -lobed, split down 1 side [not split]; corolla tube slender, lobes 3, linear; stamens ± linear, incurved, tubular, enclosing style, anther long-exserted; lip oblong, 2-lobed, plane. Fruit: spheric.
± 50 species: southern Asia, Madagascar. (Greek: sweet snow, for fragrant white flowers) [Wood et al. 2000 Edinburgh J Bot 57:261–270]
Leaf: ligule 4–5 cm, blade elliptic or narrowly so, to 55 × 10 cm. Inflorescence: to 15 cm, bract 4–10 cm, lanceolate. Flower: perianth ± yellow, exserted; lip 3–4 cm, oblanceolate, anther 11–13 mm, ± linear; stigma barely exceeding anther, conic, hairy.
Spreading along perennially irrigated creek bed in redwood forest, from garden, by fragmenting rhizomes; ± 115 m. San Francisco Bay Area (Santa Cruz Co.); native to India, Sri Lanka. According to Dean Taylor, collector of specimens in UC/JEPS, inflorescences abort in October before flowers open unless special care is given, there otherwise is no evidence of sexual reproduction, and the plants he has seen appear to be best characterized as garden escapes (although they evidently have only "escaped" to irrigated land).
