Exostema is a genus of flowering plants in the family Rubiaceae. It consists of trees and shrubs, endemic to the neotropics, with most of the species occurring in the West Indies.[1][2]

Description

Exostema is a genus of neotropical trees and shrubs. The flowers have a slender corolla tube with recurved corolla lobes. The stamens are inserted near the base of the corolla tube and exserted well beyond its mouth. The anthers are long and basifixed.[3]

Systematics

The type species for the genus is Exostema caribaeum.[4] It is a tree of Central America and the Caribbean. Its lumber is of limited use.[1]

Exostema was first named by Christiaan Hendrik Persoon as a subgenus of Cinchona.[5] It was first validly published as a genus by Aimé Bonpland in 1807.[6][7] The generic name is derived from the Ancient Greek words, exo, meaning "outside", and stema, "stamen".[8]

Exostema is probably polyphyletic.[9]
