Melastoma malabathricum

provided by wikipedia EN

Melastoma malabathricum, known also as Malabar melastome, Indian rhododendron, Singapore rhododendron, planter's rhododendron and senduduk, is a flowering plant in the family Melastomataceae. This plant is native to Indomalaya, Japan and Australia, and is usually found between 100 and 2,800 m on grasslands and sparse forests.[2] It has been used as a medicinal plant in certain parts of the world,[3] but has been declared a noxious weed in the United States.[4] M. malabathricum is a known hyperaccumulator of aluminium, and as such can be used for phytoremediation.[5]

Taxonomy

The taxonomy of the genus Melastoma requires a complete revision.[6] Early genetics studies were published from 2001,[7] through to recently,[8] 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.[9]

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,[10][11] except by authorities in Queensland.[12][13] 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.[14]

Description

M. malabathricum grows wild on a wide range of soils, from sea-level up to an altitude of 3000 meters. It is an erect, free-flowering shrub that grows to a height of about 3 meters. The plant is branched, and has reddish stems that are covered with bristly scales and minute hairs. Its leaves are simple, elliptic lanceolate with a rounded base, are up to 7 cm long, are have three distinct main veins running from base to apex. Its flowers are borne on short terminal cymes 2 to 8 cm across. Its fruit is a berry, which when ripe breaks irregularly to expose its soft, dark blue pulp and orange seeds.[15]

Melastoma septemnervium

provided by wikipedia EN

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.
