__NOTOC__
:Family: Leguminosae - Papilionoideae
== Synonyms ==
''Crotalaria caerulaea'' Jacq.
== Vernacular names ==
*Blue rattleweed, purple rattlebox, warty crotalaria (En)
*Malaysia: gegiring jantan
*Philippines: bulai laua (Tagalog), gulinggam (Sulu), reging (Bagobo). Burma (Myanmar): hing hai bay yai
*Cambodia: voë(lli) châ:ng, khnâ:ng prâmat' (Pursat), châ:ngkrâ:ng tma:t
*Laos: (ko: hnha:z) lem (Houa Pan)
*Thailand: kraphohphi (south-eastern), makhing-nu (northern), hinghai-baiyai (central)
*Vietnam: sục sạc (southern).
== Distribution ==
Originating from tropical Asia, now pantropically distributed.
== Uses ==
Green manure. Roots are used against fever (Cambodia, Laos) and stomach pain (Vietnam). Used in India to purify blood, to cure skin diseases, and as emmenagogue. It produces a neutral seed-gum polysaccharide and the flowers produce kaempferol. Seed caused liver damage to test animals. It is a potential ornamental.
== Observations ==
Annual, subwoody herb, 0.5-1 m tall, with many quadrangular, velvety hairy, yellow branches. Leaves simple, ovate to elliptical, 5-14 cm × 4-9 cm, pubescent; petiole 4-8 mm long; stipules sickle-shaped, 5-20 mm × 4-14 mm, auricled, persistent. Inflorescence a lax raceme, 5-25 cm long, leaf-opposed, with up to 24 flowers; pedicel filiform, up to 5 mm long; bracts linear-acuminate, 4 mm long; calyx campanulate, 7-11 mm long, hairy, with subequal triangular-acuminate lobes; corolla blue; standard elliptical to suborbicular, 14 mm in diameter; wings ovate-oblong, 13 mm × 6 mm; keel 12 mm × 6 mm, incurved in the middle. Pod oblongoid, 3-5 cm × 0.8-1.2 cm, short stalked, about 16-seeded. Seed heart-shaped, 3 mm in diameter, blackish. ''C. verrucosa'' is found in fallow fields and on marshy ground, along rivers and roads, up to 1200 m altitude. It fixes nitrogen and is self-pollinating.
