Description : Erect perennial to 200 cm; stem sturdy, grooved, hollow, branched or not, sometimes somewhat scabrid above. Leaves 1–3 times pinnate, oblong to broadly triangular in outline, decreasing upwards, 5–25 by 4.5–19 cm including a ± winged petiole shorter than rachis; leaflets narrowly elliptic to broadly ovate, 8–60 by 2–35 mm, margins serrate to incised. Peduncles (0–)3–18 cm long, leaf-opposed. Bracts 0(–1). Rays 5–26, 0.5–5.5 cm long, equal or not, usually shortly scabrid, sometimes ± flattened. Bracteoles several, equalling or shorter than pedicels. Pedicels 25–45, 2–8 mm long, equal or not. Sepals ca 0.5 mm long. Petals 0.5–2 mm long. Fruit 2–2.5 mm long; styles 1–3 mm long.
Thailand : NORTHERN: Chiang Mai (Doi Chiang Dao, Khun Khong, Doi Suthep, Doi Inthanon, Mae Sanam, Mae Rim, Mae Chaem, Doi Ngao, Doi Pha Hom Pok); NORTH-EASTERN: Phetchabun (Phu Miang), Loei (Phu Luang), Nong Khai (Chaiyaburi), Nakhon Phanom; EASTERN: Nakhon Ratchasima; CENTRAL: Krung Thep Maha Nakhon (Bangkok); PENINSULAR: Yala (Tandao).

Ecology : Marshy ground, streamsides, deciduous or evergreen forests, 600–1,700 m alt.

Uses: Used raw or cooked as a vegetable with rice.
Notes: Despite the extensive synonymy, this is not a particularly olymorphic species, although the leaves do vary greatly in size and shape. Murata (1973) recognized 3 taxa from Thailand: subsp. javanica var. javanica with once to twice pinnate leaves, ovate leaflets and 0.5–3 cm long rays 5–15 in numbe var. japonica (syn. Oenanthe benghalensis) differing from it in 2–3 times pinnate, flaccid leaves with narrow leaflets and subsp. stolonifera with once to twice pinnate leaves, the leaflets larger, umbels with 13–26 rays 2.5–5.5 cm in length. While the extremes of these taxa are clearly distinct there are too many intermediates throughout the range of the complex to warrant formal separation.
