Melastoma polyanthum is a species of shrubs, of the plant family Melastomataceae. It widely distributed across Southeast Asia through to Australia, where it occurs mainly near the coasts of the north and east of the country. Common names include Lasiandra, Blue Tongue, Straits Rhododendron and Chinese Wild Peony. Its fruits are edible though staining the mouth black, and the leaves and sap are used in herbal medicine.
M. polyanthum is a shrub, to 2.5 metres. The leaves are opposite, elliptical, coarsely hairy, with three longitudinal veins. The 8 mm petiole too is hairy. The bark is gray and scaly. The flowers are purple, to 8 cm, with yellow stamens. There are 5 petals.
The plant is used to make grass jelly (cincau perdu) in Indonesia. The fruits ripen to dark gray, and contain an edible purple pulp around the seeds. It stains the mouth black (hence the name of the genus).

Melastoma malabathricum, known also as Malabar Melastome, Indian Rhododendron and Singapore Rhododendron (Malay: Senduduk; Thai: โคลงเคลงขี้นก, Khlong khleng khi nok) is a flowering plant in the family Melastomataceae.
It is present in Indonesia, Japan, Burma, Cambodia, Laos, India, Malaysia, Nepal, Philippines, Thailand and Vietnam. It is usually found between 100 and 2,800 m on grasslands and sparse forests. It has been declared a noxious weed in the United States.
The taxonomy of the genus Melastoma requires a complete revision. Early genetics studies were published from 2001, through to recently, but a revision based on them has yet to be. In 2001 Karsten Meyer proposed a revision in which the species Melastoma affine and other species were subsumed within this species M. malabathricum.
In Australia, currently most authorities do not accept this; instead the naturally occurring populations in Western Australia, Northern Territory, Queensland and north eastern New South Wales remain recognised as M. affine, except by authorities in Queensland. Australian populations which occur as weeds, having different flowers, for example in Warraroon Reserve, Lane Cove, Sydney, further south than the natural distribution of M. affine, are introduced plants of this M. malabathricum L. species.
