Melastomataceae (

dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species.[3][4] Melastomes are annual or perennial herbs, shrubs, or small trees
.

Description

The leaves of melastomes are somewhat distinctive, being

, and usually with 3-7 longitudinal veins arising either from the base of the blade, plinerved (inner veins diverging above base of blade), or pinnately nerved with three or more pairs of primary veins diverging from the mid-vein at successive points above the base.

Flowers are perfect, and borne either singly or in terminal or axillary, paniculate cymes.

Ecology

A number of melastomes are regarded as

Koster's curse (Clidemia hirta), Pleroma semidecandrum and Miconia calvescens
, but many other species are involved.

Taxonomy

Under the APG III system of classification, the seven genera from Memecylaceae are now included in this family.[2]

Genera

There are some 167 accepted genera in the Melastomataceae family as of October 2023. They are:[5]
