Distribution: —Asia ( India, Myanmar, China, Thailand, Laos, Cambodia, Vietnam, Malaysia, Korea, Japan), Australia, Hawaii. ( Figure 23 View FIGURE 23 ).

Ecology: —Open places in deciduous dipterocarp forests, elevation 13–1500 m.

Notes: — Crotalaria sessiliflora is most similar in habit and leaf morphology to C. calycina , but differs by its lanceolate bracts, purple collora and sessile ovary and pods. The flowering and fruiting material provides additional taxonomic characters. Crotalaria venusta was synonymized under C. sessiliflora by Baker (1876), but Ansari (1993) reinstated to species again, which is not followed here.
