Swainsona is a large genus of flowering plants native to Australasia. There are 85 species, all but one of which are endemic to Australia.
A member of the family Fabaceae (legumes), it is most closely related to the New Zealand genera Montigena (scree pea), Clianthus (kakabeak), and Carmichaelia (New Zealand broom).[1]
Swainsona is named after English botanist Isaac Swainson.
A few species are known to produce swainsonine, a phytotoxin harmful to livestock (see Locoweed). In Australia, animals intoxicated with swainsonine are said to be pea struck.[2]
