Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both North and south of the Equator.
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline.
Brachystegia is a genus of tree of the subfamily Detarioideae that is native to tropical Africa.
The Llanos is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome.
The subfamily Detarioideae is one of the subdivisions of the plant family Fabaceae (legumes). This subfamily includes many tropical trees, some of which are used for timber or have ecological importance. The subfamily consists of 84 genera, most of which are native to Africa and Asia. Pride of Burma and tamarind are two of the most notable species in Detarioideae. It has the following clade-based definition:
The most inclusive crown clade containing Goniorrhachis marginataTaub. and Aphanocalyx cynometroidesOliv., but not Cercis canadensisL., Duparquetia orchidaceaBaill., or Bobgunnia fistuloides(Harms) J. H. Kirkbr. & Wiersema.
Placodiscus is a genus of plant in family Sapindaceae. The following species are accepted by Plants of the World Online:
Humularia is a genus of flowering plants in the legume family, Fabaceae. It includes 34 species native to sub-Saharan Africa, ranging from South Sudan to Cameroon, Angola, Malawi, and Tanzania. Species include herbs with woody bases and occasionally small shrubs. Typical habitats include seasonally-dry tropical woodland, wooded grassland, scrub, and grassland, often along stream banks, swamp margins, floodplains, and sandy areas, and sometimes in montane areas. The genus belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae.
Luetzelburgia is a genus of flowering plants in the legume family, Fabaceae. It includes 14 species of trees and shrubs native to Brazil, Bolivia, and Colombia. Typical habitat is seasonally-dry tropical lowland woodland and wooded grassland, and occasionally lowland rain forests. The genus belongs to the subfamily Faboideae. It was traditionally assigned to the tribe Sophoreae, mainly on the basis of flower morphology; recent molecular phylogenetic analyses assigned Luetzelburgia into an informal, monophyletic clade called the "vataireoids". Keys for the different species of Luetzelburgia have been published.
Neonotonia is a genus of flowering plants in the legume family, Fabaceae. It includes two species of scandent or climbing herbs native to sub-Saharan Africa, Yemen, India, and Sri Lanka. Typical habitats include seasonally-dry tropical forest, woodland, thicket, scrub, wooded grassland, grassland, and cultivated areas. It belongs to the subfamily Faboideae.
Physostigma is a genus of flowering plants in the family Fabaceae. It includes five species of erect or climbing herbs and subshrubs native to sub-Saharan Africa. They grow in tropical swamp and riverine vegetation and seasonally-dry forest, open woodland, and grassland in the Guineo-Congolian and Zambezian regions. The genus belongs to subfamily Faboideae.
Platysepalum is a genus of flowering plants in the family Fabaceae. It includes 13 species of small trees, shrubs, or lianas native to tropical Africa, from Senegal to Tanzania and south to Angola and Mozambique. Most species are native to the Guineo-Congolian forests of west and west-central Africa, and one is native to the tropical Zanzibar-Inhambane coastal forests of Africa's eastern coast. Habitats include tropical rain forest and seasonally-dry lowland forests, often in disturbed areas. It belongs to subfamily Faboideae.
Poiretia is a genus of flowering plants in the legume family, Fabaceae. It includes 12 species of twining, scandent, or erect herbs and shrubs native to the tropical Americas, ranging from southern Mexico to northern Argentina, including Cuba and Hispaniola. Most species are native to eastern Brazil, Paraguay, and northern Argentina; Poiretia punctata ranges further north and west to northern South America, Central America, Mexico, and the Caribbean. Typical habitats include seasonally-dry tropical to subtropical riverine forest, woodland (cerrado), grassland, and shrubland.
Pseudarthria is a genus of flowering plants in the legume family, Fabaceae. It includes seven species of herbs, subshrubs, and shrubs native to tropical Africa and Asia. Typical habitats are seasonally-dry tropical forest margins, grassland, and open or disturbed areas. It belongs to subfamily Faboideae.
Psophocarpus is a genus of flowering plants in the legume family, Fabaceae. It includes nine species of climbing herbs or subshrubs native to tropical Africa. Typical habitats include seasonally-dry tropical forest and forest margins, moist wooded grassland and grassland, thicket, swamp, and secondary vegetation. It belongs to subfamily Faboideae.
Poissonia is a genus of flowering plants in the legume family, Fabaceae. It includes five species of trees, shrubs, and herbs native to Peru, Bolivia, and northwestern Argentina. Typical habitats include seasonally-dry tropical and subtropical forest and shrubland, generally along river and stream banks, and open vegetation in arid areas. It belongs to the subfamily Faboideae, tribe Robinieae.
Tropical vegetation is any vegetation in tropical latitudes. Plant life that occurs in climates that are warm year-round is in general more biologically diverse that in other latitudes. Some tropical areas may receive abundant rain the whole year round, but others have long dry seasons which last several months and may vary in length and intensity with geographic location. These seasonal droughts have great impact on the vegetation, such as in the Madagascar spiny forests. Rainforest vegetation is categorized by five layers. The top layer being the upper tree layer. Here you will find the largest and widest trees in all the forest. These trees tend to have very large canopy's so they can be fully exposed to sunlight. A layer below that is the middle tree layer. Here you will find more compact trees and vegetation. These trees tend to be more skinny as they are trying to gain any sunlight they can. The third layer is the lower tree area. These trees tend to be around five to ten meters high and tightly compacted. The trees found in the third layer are young trees trying to grow into the larger canopy trees. The fourth layer is the shrub layer beneath the tree canopy. This layer is mainly populated by sapling trees, shrubs, and seedlings. The fifth and final layer is the herb layer which is the forest floor. The forest floor is mainly bare except for various plants, mosses, and ferns. The forest floor is much more dense than above because of little sunlight and air movement.
Philenoptera is a genus of flowering plants in the legume family, Fabaceae. It includes 11 species of trees, shrubs, and more rarely lianas native to sub-Saharan Africa. Typical habitats include seasonally-dry tropical forest, woodland, wooded grassland, and bushland. Four species are native to the Zambezian region, 3 species to the Sudanian region, 2 species to the Zanzibar-Inhambane and Tongaland-Pondoland regions, 1 species to the Somali-Masai region, 1 species to the Guineo-Congolian region, and 1 to Madagascar.
Chytranthus is a genus of flowering plants belonging to the family Sapindaceae.
Deinbollia is a genus of flowering plants belonging to the family Sapindaceae.
