Kennedia lateritia, commonly known as Augusta kennedia, is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is a woody climber with twining stems, trifoliate leaves and orange-red and yellow flowers arranged in groups of up to twenty-four.
Kennedia lateritia is a woody climber with twining stems that cover low vegetation or sometimes climb trees to a height of up to . Its leaves are trifoliate with elliptic, round or broadly egg-shaped leaflets long and wide, each leaf on a petiole long and the end leaflet on petiolule up to about long. There are stipules long at the base of the petiole. The flowers are arranged in up to eight clusters of three along a peduncle up to long, each flower on a pedicel about long. The five sepals are long and the petals are long. The standard petal is brick red with a yellow base and the wings are about the same length as the keel. Flowering occurs from October to November and the fruit is a cylindrical pod long and wide.
Kennedia lateritia was first formally described in 1864 by Ferdinand von Mueller in Fragmenta Phytographiae Australiae. The specific epithet (lateritia) means "brick red".
Augusta kennedia grows in low coastal heath, often among granite outcrops in the Augusta-Cape Leeuwin area of south-western Western Australia.
This species of twining pea is listed as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and as "Threatened Flora (Declared Rare Flora — Extant)" (as Kennedia macrophylla) by the Department of Biodiversity, Conservation and Attractions. The main threats to the species include trampling by tourists, inappropriate fire regimes and land clearing.
