Description
Kennedia rubicunda is a twining or prostrate herb with stems up to Script error: No such module "convert". long and covered with rusty-brown hairs. The leaves are trifoliate on a petiole Template:Cvt long, the leaflets egg-shaped to lance-shaped, Template:Cvt long and Template:Cvt wide with lance-shaped stipules Template:Cvt long at the base of the petiole. Dark red pea flowers are arranged in racemes of up to twelve on a peduncle Template:Cvt long, each flower on a pedicel Template:Cvt long. The sepals are Template:Cvt long and densely covered with rusty-brown hairs and the petals are Template:Cvt long. Flowering mostly occurs from September to December and the fruit is a rusty-hairy, flattened pod Template:Cvt long containing ten to fifteen seeds.[1][2][3][4]
Taxonomy
Dusky coral pea was first formally described in 1793 by Dutch botanist George Voorhelm Schneevoogt, who gave it the name Glycine rubicunda in his book Icones Plantarum rariorum.[5][6] In 1804 it was published under its current name by French botanist Étienne Pierre Ventenat in his book, Jardin de la Malmaison.[7][8] The specific epithet (rubicunda) refers to the species' red flowers.[9]
Distribution and habitat
Kennedia rubicunda is widespread in a variety of habitats, including in forests and rainforest margins, on the coast and nearby tablelands of Queensland, New South Wales and far eastern Victoria.[1][2][10] It is an introduced species in India, Tasmania and the North Island of New Zealand[11] (where it is considered a weed).[12]
Ecology
Flowers of K. rubicunda are pollinated by birds.[13] Seed dispersal by ants (myrmecochory) has been reported,[14] in which ants are attracted to fatty acid-rich elaiosomes attached to the outside of the seeds.[15] The plant is killed by bushfire but regenerates from seed dormant in the soil and is often abundant after fire.[2][16] K. rubicunda forms a symbiosis with soil nitrogen fixing bacteria (rhizobia) resulting in the formation of nodules on the roots that fix atmospheric nitrogen which is used for plant growth.[17]
Use in horticulture
This plant is noted for its vigour and can be used to cover embankments or structures.[18] The species is adapted to a range of well-drained soils and adapts to positions with sun or partial shade.[19] It is resistant to drought and has some frost tolerance.[19] The species can be propagated by scarified seed or cuttings of semi-mature growth.[19]
