Kennedia rubicunda
Kennedia rubicunda, commonly known as the dusky coral pea, is a species of flowering plant in the family Fabaceae and is endemic to eastern continental Australia. It is a twining or prostrate herb with trifoliate leaves and dark red or purple flowers. Description. "Kennedia rubicunda" is a twining or prostrate herb with stems up to long and covered with rusty-brown hairs. The leaves are trifoliate on a petiole long, the leaflets egg-shaped to lance-shaped, long and wide with lance-shaped stipules long at the base of the petiole. Dark red pea flowers are arranged in  racemes of up to twelve on a peduncle long, each flower on a pedicel long. The sepals are long and densely covered with rusty-brown hairs and the petals are long. Flowering mostly occurs from September to December and the fruit is a rusty-hairy, flattened pod long containing ten to fifteen seeds. 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". In 1804 it was published under its current name by French botanist Étienne Pierre Ventenat in his book , "Jardin de la Malmaison". The specific epithet ("rubicunda") refers to the species' red flowers. 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. It is an introduced species in India, Tasmania and the north island of New Zealand (where it is considered a weed). Ecology. Flowers of "K. rubicunda" are pollinated by birds. Seed dispersal by ants (myrmecochory) has been reported, in which ants are attracted to fatty acid-rich elaiosomes attached to the outside of  the seeds. The plant is killed by bushfire but regenerates from seed dormant in the soil and is often abundant after fire. "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. Use in horticulture. This plant is noted for its vigour and can be used to cover embankments or structures. The species is adapted to a range of well-drained soils and adapts to positions with sun or partial shade. It is resistant to drought and has some frost  tolerance. The species can be propagated by scarified seed or cuttings of semi-mature growth.
