Canavalia is a genus of plants in the legume family (Fabaceae) that comprises approximately 62 species of tropical vines.[1] Members of the genus are commonly known as jack-beans. It has a pantropical distribution.[1]
The species of Canavalia endemic to the Hawaiian Islands were named ʻāwikiwiki by the Native Hawaiians. The name translates to "the very quick one"[2] and comes from the Hawaiian word for "fast". The genus name is derived from the Malabar word for the species, kavavali, which means "forest climber."[3]
Uses[edit]
Several species are valued legume crops, including common jack-bean (C. ensiformis), sword bean (C. gladiata) and C. cathartica. At least the first makes a beneficial weed- and pathogen-suppressing living mulch.[4] The common jack-bean is also a source of the lectin concanavalin A, which is used as a reagent in glycoprotein biochemistry and immunology. The jack-bean is also a common source of purified urease enzyme used in scientific research.
The bay bean (Canavalia rosea) is supposedly mildly psychoactive when smoked, and is used in tobacco substitutes.
Ecology[edit]
Some animals have adaptations to the defensive chemicals of jack-beans. Caterpillars such as that of the two-barred flasher (Astraptes fulgerator) are sometimes found on Canavalia. The plant pathogenic ascomycete fungus Mycosphaerella canavaliae was described from a jack-bean. Introduced herbivores have wreaked havoc on Canavalia on the Hawaiian Islands and made some nearly extinct; it may be that these lost their chemical defenses because no herbivorous mammals existed in their range until introduced by humans. The usually bright pea-flowers are pollinated by insects such as solitary bees and carpenter bees such as Xylocopa confusa.
History[edit]
The genus name Canavalia was, as recently as 1913, known as Canavali.[5]
