Melastoma sanguineum

Melastoma sanguineum is called red melastome or fox-tongued melastoma in English. They are erect shrubs or small slender trees with medium-sized violet-pink colored flowers with 6 petals that have made them attractive for cultivation. The leaves have the 5 distinctive longitudinal veins (nerves) typical of plants in the family Melastomataceae.
