Palaquium is a genus of about 120 species of trees in the family Sapotaceae. [4] Their range is from India across Southeast Asia, Malesia, Papuasia, and Australasia, to the western Pacific Islands. [3] [5]
Within their range, Palaquium species are mostly found in the Philippines and Borneo. In Borneo, many species are recorded in the Malaysian states of Sabah and Sarawak. [5]
The leaves are typically spirally arranged and often clustered near twig ends. Flowers are mostly bisexual, though some unisexual instances are known. Fruits are one- or two-seeded with rare instances of several seeds. Palaquium habitats are coastal, lowland mixed dipterocarp, swamp, and montane forests. [5]
Some species, for example Palaquium gutta , are well known for producing gutta-percha latex. [5]
As of November 2013 [update] The Plant List recognises 120 accepted species: [6]
Hopea is a genus of plants in the family Dipterocarpaceae. The genus was named after John Hope, 1725–1786, the first Regius Keeper of the Royal Botanic Garden, Edinburgh. It contains some 113 species, distributed from Sri Lanka and southern India to southern China, and southward throughout Malesia to New Guinea. They are mainly main and subcanopy trees of lowland rainforest, but some species can become also emergent trees, such as Hopea nutans.
Madhuca is a genus of plants in the family Sapotaceae first described as a genus in 1791.
Payena is a genus of plants in the family Sapotaceae described as a genus in 1844.
Xylopia is a genus of flowering plants in the family Annonaceae. They are mostly trees and some shrubs. There are about 160 species distributed in Asia, Africa, and the Americas.
Salacia is a genus of plants in the family Celastraceae. They are woody climbers naturally found in tropical regions.
The Sapotoideae are a subfamily of the flowering plant family Sapotaceae. Plants in the subfamily are characterized by their leather-like leaves, often growing in a stipule fashion.
Planchonella is a genus of flowering trees in the gutta-percha family, Sapotaceae. Named in honour of Jules Émile Planchon, it contains around 100 mainly tropical species, two of which occur in South America and about 18 in Australasia. It was described by Jean Baptiste Louis Pierre. The genus is included in the larger genus Pouteria by some authorities, hence species such as Planchonella queenslandica are also known as Pouteria queenslandica.
Aidia is a genus of flowering plants in the family Rubiaceae. It was described by João de Loureiro in 1790. It has a wide distribution area and occurs in tropical Africa, tropical and subtropical Asia and the western Pacific.
Mussaenda is a genus of flowering plants in the family Rubiaceae. They are native to the African and Asian tropics and subtropics. Several species are cultivated as ornamental plants.
Gynochthodes is a genus of flowering plants in the family Rubiaceae. The genus is found from Madagascar to tropical and subtropical Asia and the Pacific region.
