There are approximately 99 accepted species in the legume tree genus Albizia , the silk trees, sirises, or albizias. [1]
Numerous species placed in Albizia by early authors were eventually moved to other genera, particularly Archidendron and many other Ingeae, as well as certain Acacieae, Mimoseae, and even Caesalpinioideae and Faboideae. [2]
The delimitation of Falcataria and Pithecellobium - close relatives of Albizia - is notoriously complex, with species having been moved between the genera time and again, and probably will continue to do so. Other closely related genera like Chloroleucon and Samanea are often merged with Albizia entirely. [2]
and others
Dalbergia is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic Dalbergia clade : the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and southern Asia.
Cassia is a genus of flowering plants in the legume family, Fabaceae, and the subfamily Caesalpinioideae. Species are known commonly as cassias. Cassia is also the English common name of some species in the genus Cinnamomum of the family Lauraceae. 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.
Indigofera is a large genus of over 750 species of flowering plants belonging to the pea family Fabaceae. They are widely distributed throughout the tropical and subtropical regions of the world.
Cynometra is genus of tropical forest trees with a pantropical distribution. It is particularly important as a forest component in west Africa and the neotropics. Cynometra alexandri (muhimbi) is a familiar timber tree of central and east Africa. The genus is a member of the subfamily Detarioideae. It has been suggested that Cynometra is polyphyletic and is in need of revision. In 2019, beside description of 4 new species, Aleksandar Radosavljevic suggested that the species formerly recognized as Maniltoa should be included in this genus and some of the mainland tropical African species excluded from this genus because of their jointed pedicels and dehiscent fruits.
Albizia lebbeck is a species of plant in the family Fabaceae, native to the Indian subcontinent and Myanmar. It is widely cultivated and naturalised in other tropical and subtropical regions, including Australia. Common names in English include siris, Indian siris, East Indian walnut, Broome raintree, lebbeck, lebbek tree, frywood, koko and woman's tongue tree. The latter name is a play on the sound the seeds make as they rattle inside the pods. Siris is also a common name of the genus Albizia.
Chamaecrista is a genus of flowering plants in the pea family, Fabaceae, subfamily Caesalpinioideae. Members of the genus are commonly known as sensitive pea. Several species are capable of rapid plant movement. Unlike the related genera Cassia and Senna, members of Chamaecrista form root nodules.
Archidendron is a genus of flowering plants in the pea family, Fabaceae. It includes 98 species which range from India through Indochina, southern China, Taiwan, Malesia, and Papuasia to Queensland and New South Wales.
Senegalia is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of Acacia. The genus was considered polyphyletic and required further division, with the genera Parasenegalia and Pseudosenegalia accepted soon after.
Vachellia is a genus of flowering plants in the legume family, Fabaceae, commonly known as thorn trees or acacias. It belongs to the subfamily Mimosoideae. Its species were considered members of genus Acacia until 2009. Vachellia can be distinguished from other acacias by its capitate inflorescences and spinescent stipules. Before discovery of the New World, Europeans in the Mediterranean region were familiar with several species of Vachellia, which they knew as sources of medicine, and had names for them that they inherited from the Greeks and Romans.
Hippocratea is a genus of flowering plants in the family Celastraceae, usually lianas, native to tropical and subtropical North America, South America and Africa.
Pseudabizzia niopoides is a species of flowering plant in the pea family (Fabaceae). It is a tree native to the tropical Americas, ranging from southern Mexico to northeastern Argentina, including the Leeward and Windward Islands in the Caribbean.
