The genus Ammopiptanthus, endemic to the eastern desert of Central Asia, includes two species: A. mongolicus (Maxim.) Cheng f. and A. nanus (M. Pop.) Cheng f.
Ammopiptanthus is the only genus of evergreen broadleaf shrub in the northwest desert of China and both species are dominant in the local vegetation, so this genus plays an important role in fixing moving sands and delaying further desertification. The biological property of Ammopiptanthus evergreen broadleaf has been viewed as an ancestral trait that identifies it as a Tertiary relict taxon. The vegetation in northwest China was dominated by evergreen and/or deciduous broadleaf forests in the early Tertiary period according to the fossil evidence. When subsequent changes made the climate colder and drier from the early Miocene (24–16 Ma) in Central Asia, the forests were gradually replaced by steppe and then by desert. Today, their habitats are stony and/or sandy deserts where the climate is arid (annual precipitation ranges from 100 to 160 mm) and the temperature varies from below -30 °C in the winter to +40 °C in the summer. Because of low seed germination rates in the harsh environments and increasing anthropogenic pressures in their natural range, both A. mongolicus and A. nanus have been categorized as 'endangered' species. As a relict survivor of the evergreen broadleaf forest in this region from the Tertiary period, Ammopiptanthus has acquired the strong ability to adapt to the dry and extremely cold environments. The characteristics described above have recently attracted scientific attention to their anatomy, cold and drought stress resistance, and genetic diversity and geographic differentiation. [1]
Ammopiptanthus comprises the following species: [2] [3] [4]
The status of the following species is unresolved: [4]
Podocytisus caramanicus is a species of flowering plant in the family Fabaceae. It is a shrub native to the western Balkan Peninsula and southern Turkey. It is the only member of the genus Podocytisus. It belongs to the subfamily Faboideae.
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.
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.
Dipteryx is a genus containing a number of species of large trees and possibly shrubs. It belongs to the "papilionoid" subfamily – Faboideae – of the family Fabaceae. This genus is native to South and Central America and the Caribbean. Formerly, the related genus Taralea was included in Dipteryx.
The genus Tylosema is in the plant family Fabaceae and encompasses four accepted species of perennial legumes native to southern and central Africa. These are semi-woody viniferous plants broadly distributed from Sudan and Ethiopia south to Angola and South Africa. Coetzer and Ross originally described four Tylosema species:
Gigasiphon is a genus of plants in the family Fabaceae. The genus is circumscribed is defined by "a long-tubular hypanthium, an arborescent habit, and a calyx divided into two lobes." It includes five species native to eastern Africa, Madagascar, the Philippines, New Guinea, and Lesser Sunda Islands.
Haplormosia is a monotypic genus of legumes in the family Fabaceae. Its only species is Haplormosia monophylla, commonly known as Liberian black gum, native to Cameroon, Ivory Coast, Liberia, Nigeria, and Sierra Leone. It is threatened by habitat loss.
Orphanodendron is a genus of legume in the legume family, Fabaceae. It includes two species of trees native to Colombia, which grow in tropical lowland forest. The genus is in subfamily Faboideae.
Adenolobus is a genus of African flowering plants in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae.
Barklya is a genus of Australian trees in the legume family, Fabaceae. It belongs to the subfamily Cercidoideae. The sole species is Barklya syringifolia, commonly known as golden crown or golden glory. It grows in rainforest to 20 metres tall. Recorded from Queensland and New South Wales in rain forest. It is often used as an ornamental.
Baudouinia is a genus of flowering plants in the legume family, Fabaceae. It includes six species which are all endemic to Madagascar. It belongs to the subfamily Dialioideae.
Disynstemon paullinioides is a species of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. It is a liana that is native to Madagascar. It is the only member of the genus Disynstemon.
Pterocarpus dubius is a species of flowering plant in the family Fabaceae native to Venezuela, Guyana, and northern Brazil in northern South America.
Hesperolaburnum platycarpum is a species of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. It is the only member of the genus Hesperolaburnum. It is a tree or shrub endemic to Morocco.
Hypocalyptus is a genus of flowering plants in the family Fabaceae. It includes three species of shrubs, subshrubs or small trees native to the Cape region of South Africa. Typical habitats include Mediterranean-climate shrubland (fynbos) at forest margins, in rocky and sandy areas, and along streams, often at high elevations.
Monopteryx is a genus of flowering plants in the family Fabaceae. It includes three species of trees native to the Amazon rainforest of northern South America, ranging through parts of Colombia, Venezuela, northern Brazil, and French Guiana. They grow in non-inundated lowland tropical rain forest on sandy soil. The genus belongs to subfamily Faboideae. Members of this genus produce hydroxypipecolic acids in their leaves.
Piptanthus is a genus of flowering plants in the legume family, Fabaceae. It includes two species of shrubs native to the Himalayas, Tibet, Myanmar, and western China. They grow in montane grassland, thicket, and forest margins.
Sellocharis paradoxa is a species of flowering plants in the family Fabaceae. It belongs to the subfamily Faboideae. It is native to southern Brazil and is the only member of the genus Sellocharis.
Vatairea is a genus of flowering plants in the legume family, Fabaceae. It includes eight species of tall trees native to the tropical Americas, ranging from southern Mexico to Bolivia and southern Brazil. Seven species are native to northern South America, with the center of diversity in Amazonia. Vatairea lundellii ranges from southern Mexico to Panama. Most species grow in tropical rain forest, often in the inudated forests known as igapó and varzea, where they are emergent trees, growing above the forest canopy. V. macrocarpa grows in seasonally-dry forest, cerrado, and caatinga.
Pterodon is a genus of flowering plants in the legume family, Fabaceae. It includes four species of trees native to Brazil and Bolivia. Typical habitats include seasonally-dry tropical forest, woodland (cerrado), and thorn shrubland (caatinga), often on rocky outcrops. It belongs to the subfamily Faboideae.
