Kennedia is an Australian genus of around 13 species of flowering plants in the legume family Fabaceae (order Fabales). All species are endemic to Australia, with representatives found in every state. Plants in the genus are prostrate or climbing perennials, typically with softly hairy foliage and stems that become woody at the base. The leaves are alternately arranged and almost always trifoliate, bearing stipules at the base of each petiole and small stipellae at the base of the leaflets.
The flowers are relatively large and showy, displaying the characteristic pea-flower structure of Fabaceae. Colours range from red and coral through blue and violet to near-black — an unusual palette within the family. Nine of the ten stamens are fused into an open sheath around the style, which is slender and thread-like. The fruit is a flattened or cylindrical pod. Kennedia was first formally described in 1805 by the French botanist Étienne Pierre Ventenat in his work "Jardin de la Malmaison."
Well-known members include Kennedia prostrata (running postman), a prostrate ground-cover with bright red flowers widespread across southern Australia; Kennedia rubicunda (dusky coral pea), a vigorous climber of eastern Australia with deep-red flowers; Kennedia coccinea (coral vine), a Western Australian species; and Kennedia nigricans (black coral pea), notable for its near-black flowers with a yellow blotch.
Etymology
The genus name Kennedia honours John Kennedy, a partner in the prominent nursery firm Lee and Kennedy of Hammersmith, London. It was bestowed by Étienne Pierre Ventenat when he formally described the genus in 1805.
Distribution
Kennedia is endemic to Australia, with species present in every Australian state. The greatest diversity is concentrated in Western Australia, where most species are confined; several species, including Kennedia prostrata and Kennedia rubicunda, extend through south-eastern mainland states and Tasmania.
Taxonomy Notes
The genus Kennedia was first formally described in 1805 by Étienne Pierre Ventenat in Jardin de la Malmaison. It belongs to the family Fabaceae (order Fabales) and comprises around 13 accepted species according to the Australian Plant Census (as of October 2021), or 23 descendants per GBIF. The Australian Plant Census is the authoritative checklist for the accepted species list within Australia.
