Chorizema, commonly known as flame peas, [3] is a genus of flowering plants in the family Fabaceae and is endemic to Australia.

Contents

Description

Plants in the genus Chorizema are mostly shrubs or subshrubs, sometimes climbers, usually with simple leaves arranged in opposite pairs, the flowers usually arranged in racemes, each flower on a short pedicel. The sepal lobes are more or less equal, the upper pair broader and partly joined, the standard petal more or less round or kidney-shaped, the wings oblong and much longer than the keel. The fruit is an oval pod containing 4 to 32 seeds. [3] [4] [5]

Taxonomy

The genus Chorizema was first formally described in 1800 by Jacques Labillardière in his Relation du Voyage à la Recherche de la Pérouse , and the first species he described (the type species) was Chorizema ilicifolium . [6] [7] The genus name (Chorizema) means "divided thread", Labillardière having noted that the stamens are separate from each other. [8]

Distribution

Flame peas are endemic to the south-west of Western Australia, apart from C. parviflorum that occurs in New South Wales and Queensland. [3] [9]

Use in horticulture

This genus of peas is valued in cultivation for their colourful flowers. Most species do not tolerate frost, and in temperate regions require the protection of glass. [10]

Anigozanthos is a genus of Southwest Australian plants of the bloodwort family Haemodoraceae. The 11 species and their subspecies are commonly known as kangaroo paw or catspaw, depending on their size, and the shape and color of their flowers. A further species, previously identified as Anigozanthos fuliginosus, was separated to a monotypic genus as Macropidia fuliginosa.

<i>Aotus</i> (plant) Genus of legumes

Aotus is an Australian genus of flowering plants, within the legume family Fabaceae. Aotus species, together with other species of the tribe Mirbelieae, are often called golden peas because of their distinctive small yellow flowers. They are endemic to Australia, occurring in all states except the Northern Territory. Aotus are evergreen species. Some are widely cultivated by gardeners for their ornamental value.

<i>Eutaxia</i> Genus of legumes

<i>Darwinia</i> (plant) Genus of flowering plants

Darwinia, sometimes commonly known as mountain bells or simply bells, is a genus of about 70 species of evergreen shrubs in the family Myrtaceae, endemic to southeastern and southwestern Australia. The majority are native to southern Western Australia, but a few species occur in South Australia, New South Wales and Victoria. The genus was named in honour of Erasmus Darwin, grandfather of Charles Darwin by Edward Rudge in 1816. Most darwinias grow to a height of between 0.2 and 3 m, and many are prostrate shrubs. Most have small, simple leaves and the flowers are often grouped together, each flower with five red, white or greenish petals and ten stamens. In many species, the flowers are surrounded by large, colourful bracts, giving rise to their common names.

<i>Hakea</i> Genus of plants in the family Proteaceae endemic to Australia
