Grewioideae is a subfamily of the family Malvaceae and was first described by Hochreutiner.[1] The group is named after its type genus, Grewia,[2] which is named for the English scientist Nehemiah Grew (1641–1712). It contains a number of genera that were previously placed in the defunct family Tiliaceae.
Description[edit]
Within the Malvaceae, this subfamily has its inflorescences opposite the leaves, the corollas are usually clawed, and there is a nectar-bearing hair carpet at the base of the petals[1] and there are numerous dithecal stamens.[3] The fruit is fleshy or capsular with spines, and the seeds are winged.[1] The group is thought to have originated about 42 (± 15) million years ago.[1][4]
Taxonomy[edit]
Ulrike Brunken & Alexandra Muellner divide the Grewioideae into two clades, the Grewia clade, Grewieae Endl. and the Apeiba clade, Apeibeae Benth., on the basis of morphological and molecular evidence.[3]
