The genus Cajanus is a member of the plant family Fabaceae. There are 37 species, mainly distributed across Africa, Asia and Australasia.
Species include the pigeon pea (C. cajan), which is a significant food crop.
The natural range of Cajanus species includes West Africa, Madagascar and the Comoros, the Indian Subcontinent, Indochina, southern China and Taiwan, Malesia, New Guinea, and northern Australia. Typical habitats include seasonally-dry tropical open forest, woodland, and grassland, often in rocky or disturbed areas. Some species, including Cajanus cajan, have been introduced to the tropical Americas, elsewhere in Africa, and to central Asia. [1]
Cajanus species are used as food plants by the larvae of some Lepidoptera species including Endoclita malabaricus .
Scaevola is a genus of flowering plants in the Goodenia family, Goodeniaceae. It consists of more than 130 species, with the center of diversity being Australia and Polynesia. There are around 80 species in Australia, occurring throughout the continent, in a variety of habitats. Diversity is highest in the South West, where around 40 species are endemic.
Sesbania is a genus of flowering plants in the pea family, Fabaceae, and the only genus found in tribe Sesbanieae. Riverhemp is a common name for plants in this genus. Notable species include the rattlebox, spiny sesbania, and Sesbania sesban, which is used in cooking. Plants of this genus, some of which are aquatic, can be used in alley cropping to increase the soil's nitrogen content. The species of rhizobia responsible for nitrogen fixation in Sesbania rostrata is Azorhizobium caulinodans.
