Oenanthe benghalensis Benth. et Hook. f.

短辐水芹

Description from Flora of China

Seseli benghalense Roxburgh, Fl. Ind., ed. 1832, 2: 93. 1832; Dasyloma benghalense (Roxburgh) de Candolle; D. glaucum de Candolle.

Plants 15–60 cm. Roots fibrous. Stems usually erect, angular, branched from base. Basal petioles 1–4 cm; blade triangular-ovate, 1–2-pinnate; ultimate segments rhombic-ovate, rarely lanceolate, 5–20 × 1–5 mm. Upper leaves smaller, sessile, 1-pinnate, pinnae rhombic ovate or lanceolate. Umbels 0.5–3.5 cm across; peduncles short, 0.5–1(–2) cm, often leaf-opposed, or obsolete; bracts absent; rays 4–10, 0.5–1 cm; bracteoles numerous, linear, as long as pedicels, umbellules 8–15-flowered; pedicels 0.5–2 mm. Calyx teeth ca. 0.4 mm. Styles 1.4–1.8 mm. Fruit ovoid, 2.5–3 × 1.5–2 mm; dorsal and intermediate ribs slightly thickened, corky. Fl. May–Jun, fr. Jun–Jul.

This species has reputed medicinal value. It is very similar to, and possibly not distinct from, Oenanthe javanica (see the comment under the latter species); the two differ in umbel and fruit characters.

Moist ground at forest margins, muddy banks, irrigation ditches; 500–1500 m. Guangdong, Sichuan, Yunnan [N India].
