The Mimosoideae are a traditional subfamily of trees, herbs, lianas, and shrubs in the pea family (Fabaceae) that mostly grow in tropical and subtropical climates. They are typically characterized by having radially symmetric flowers, with petals that are twice divided (valvate) in bud and with numerous showy, prominent stamens.
Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. The genus includes 37 species and has a pantropical distribution. Species of the genera Senna and Chamaecrista were previously included in Cassia. Cassia now generally includes the largest species of the legume subtribe Cassiinae, usually mid-sized to tall trees.
Abarema is a neotropical genus in the family Fabaceae. It is native to Brazil, Cuba, and Venezuela. Most of the species can be found in the Amazon Basin and the Guyana Highlands. They have a deep-green fernlike foliage, with bipinnately compound leaves.
Sesbania is a genus of flowering plants in the pea family, Fabaceae, and the only genus found in tribe Sesbanieae. Riverhemp is a common name for plants in this genus. Notable species include the rattlebox, spiny sesbania, and Sesbania sesban, which is used in cooking. Plants of this genus, some of which are aquatic, can be used in alley cropping to increase the soil's nitrogen content. The species of rhizobia responsible for nitrogen fixation in Sesbania rostrata is Azorhizobium caulinodans.
Calandrinia is a genus of flowering plants known as purslanes and redmaids. It includes 37 species of annual and perennial herbs which bear colorful flowers in shades of red to purple and white. Species of this genus are native to the Americas, including western and southern South America, Central America, and western North America. Some species have been introduced to parts of Australia, New Zealand, southern Africa, Asia, and Europe. Over 60 species native to Australia and New Guinea that were formerly included in Calandrinia are now placed in a separate genus, Rumicastrum or Parakeelya. A single eastern Australian species named in 2022, Calandrinia petrophila, is still included in Calandrinia, but will be placed into the Australian genus when the name of the new genus is finally settled.
Dodonaea, commonly known as hop-bushes, is a genus of about 70 species of flowering plants in the soapberry family, Sapindaceae. The genus has a cosmopolitan distribution in tropical, subtropical and warm temperate regions of Africa, the Americas, southern Asia and Australasia, but 59 species are endemic to Australia.
Gastrolobium is a genus of flowering plants in the family Fabaceae. There are over 100 species in this genus, and all but two are native to the south west region of Western Australia.
Thryptomene is a genus of flowering plants in the family Myrtaceae and is endemic to Australia. Plants in the genus Thryptomene are shrubs with small leaves arranged in opposite pairs and white or pink flowers. About forty-seven species of Thryptomene, occurring in all Australian states and the Northern Territory, have been formally described.
Dichrostachys is an Old World genus of flowering plants in the family Fabaceae. Their Acacia-like leaves are bi-pinnately compound. Unlike Acacia their thorns are hardened branchlets rather than modified stipules. They are native from Africa to Australasia, but a centre of diversity is present in Madagascar.
Petrophile is a genus of evergreen shrubs, in the family Proteaceae. The genus is endemic to Australia. Commonly known as conebushes, they typically have prickly, divided foliage and produce prominently-displayed pink, yellow or cream flowers followed by grey, conical fruits.
Trachymene is a genus of herbaceous plants in the family Araliaceae. The species are native to Australia, Malesia, New Caledonia and Fiji.
Conostylis is a genus of perennial herbs in the Haemodoraceae family, commonly known as cone flowers. All species are endemic to the south west of Western Australia.
Neptunia is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae.
Polhillia is a genus of flowering plants in the family Fabaceae. It includes 11 species of shrubs and herbs native to the Cape Provinces of South Africa. They grow in Mediterranean-climate renosterveld (shrubland) and scrub-grassland, typically in heavy soils. The genus belongs to subfamily Faboideae.
The tribe Psoraleeae is one of the subdivisions of the plant family Fabaceae. Recent phylogenetics has this tribe nested within tribe Phaseoleae.
Sclerolaena is a genus of flowering plants in the family Amaranthaceae. It includes 78 species of annuals or short-lived perennials native to Australia.
Parakeelya is a genus of plants in the family Montiaceae with species native to Australia and New Guinea. These species were formerly classed in genus Calandrinia, which was discovered to be paraphyletic.
