Melastoma septemnervium are erect shrubs or small slender trees with 5 petal, medium-sized, pink flowers that have made them attractive for cultivation. The leaves have the 5 distinctive longitudinal veins (nerves) typical of plants in the family Melastomataceae.

Description

Melastoma septemnervium are erect shrubs or small trees up to 5 m tall.[2] Leaves are elliptical with short stiff hairs or scales on the upper surface and finer dense hairs on the lower surface but with a mixture of scales on the nerves.

Distribution

Native to Vietnam, southern China , the Philippines , Taiwan, Ryukyu Islands, and southern Japan .[2] Cultivated and naturalized in Hawaii but also reported to be abundant and invasive on Kauai and Hawaii Island from sea level up to 900 m elevation.[2]

Melastoma septemnervium grows in light forests, clearings, and grass lands, or on rocky slopes, but prefers mesic to wet areas and bog margin habitats in Hawaii.[2][3]

Taxonomy

Hawaiian populations of M. septemnervium were historically assigned to Melastoma malabathricum non L. but later were identified as M. candidum D. Don by Wagner et al. 1999 due to a number of consistently different traits, including a higher chromosome number (2n = 56 versus Melastoma malabathricum 2n = 24).[2]

M. septemnervium was first described by Loureiro in 1790 (Flora Cochinchinensis 1: 273–274).[4] M. septemnervium is the accepted name by some sources with M. candidum as a junior synonym,[1] but both names are used widely.
