DIURANTHERA Hemsley, Hooker’s Icon. Pl. 28: t. 2734. 1902.鹭 鸶 兰 属 lu si lan shuChen Xinqi ( 陈 心 启 Chen Sing-chi); Nicholas J. TurlandHerbs perennial, rhizomatous. Rhizome vertical, very short. Roots numerous, thickened, fleshy. Leaves several, all basal, tuftedor arranged in a lax rosette, narrowly linear to linear-oblanceolate. Scape simple or few branched, longer than leaves, proximallywith a few sterile bracts, terminating in a lax raceme. Bracts ovate to linear-lanceolate, usually shorter than flowers, membranous or± so, veined. Flowers bisexual, usually paired, shortly pedicellate; pedicel articulate or not. Tepals 6, spreading or ± so, free, linear,3–20-veined; outer ones slightly narrower or sometimes shorter than inner ones. Stamens 6, slightly shorter than tepals; filamentsfiliform; anthers dorsifixed at base, linear, base with 2 prominent, caudate appendages 1–3 mm. Ovary 3-loculed. Style filiform,long; stigma very small. Fruit a capsule, obovoid or ellipsoid, 3-angled, loculicidal. Seeds black, orbicular, flattened, base cordate.Four species: China.Except for its prominently appendaged anthers, Diuranthera is very similar to Chlorophytum, the similarity extending to the karyotypes, andsome authors treat the former genus as a highly specialized member of the latter. However, the two are here distinguished at generic level.1a. Leaves densely white powdery abaxially; tepals yellow, ca. 20-veined, inner ones much longer than outer .... 2. D. chinglingensis1b.
