Melastoma malabathricum, known also as Malabar melastome, Indian rhododendron, Singapore rhododendron, planter's rhododendron and senduduk, is a flowering plant in the family Melastomataceae native to Seychelles, tropical and subtropical Asia to Australia and western Pacific islands. [2] Despite its common names, it does not have any connection to actual rhododendrons, and belongs to the Rosids clade as opposed to the Asterids clade. This plant is usually found at elevations between 100 m and 2,800 m in grassland and sparse forest habitats. [3] It has been used as a medicinal plant in certain parts of the world, [4] but has been declared a noxious weed in the United States. [5] M. malabathricum is a known hyperaccumulator of aluminium, and as such can be used for phytoremediation. [6]
The taxonomy of the genus Melastoma requires a complete revision. [7] Early genetics studies were published from 2001, [8] through 2013, [9] 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. [10]
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 , [11] [12] except by authorities in Queensland. [13] [14] 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. malabathricumL. species. [15]
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, and have three distinct main veins running from base to apex. Its flowers are borne on short terminal cymes 2 to 8 cm across. The flowers are pink, violet or mauve. [16] Its fruit is a berry, which when ripe breaks irregularly to expose its soft, dark blue pulp and orange seeds. [17]
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.
Rhododendron is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia.
Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. Along with many other lilioid monocots, early authors considered members of this family to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like those of lilies, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009, places the family in the order Liliales, in the clade monocots. Circumscribed in this way, the family includes up to 17 genera.
Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera, almost entirely native to the Americas, from Central America to southern South America. One species of Luzuriaga occurs in New Zealand, and the genus Drymophila is endemic to south-eastern Australia.
The Xyridaceae are a family of flowering plants. This family has been recognized by many taxonomists and is known as the yellow-eyed grass family.
Austrobaileya is the sole genus consisting of a single species that constitutes the entire flowering plant family Austrobaileyaceae. The species Austrobaileya scandens grows naturally only in the Wet Tropics rainforests of northeastern Queensland, Australia.
The Calycanthaceae are a small family of flowering plants in the order Laurales. The family contains three genera and only 10 known species, restricted to warm temperate and tropical regions:
Schisandraceae is a family of flowering plants with 3 known genera and a total of 92 known species. Such a family has been recognized by most taxonomists, at least for the past several decades. Before that, the plants concerned were assigned to family Magnoliaceae and Illiciaceae.
Lardizabalaceae is a family of flowering plants.
Melastoma is a genus in the family Melastomataceae. It has over 100 species distributed around Southeast Asia, India, north to Japan, south to Australia and the Pacific Islands. The number of species should probably be reduced according to some sources. Many species have been planted around the world for the aesthetic value of their bright purple flowers.
Melastoma affine, also known by the common names blue tongue or native lassiandra, is a shrub of the family Melastomataceae. Distributed in tropical and sub-tropical forests of India, South-east Asia and Australia, it is a plant of rainforest margins. Bees are the principal pollinators of this species.
An archaeophyte is a plant species which is non-native to a geographical region, but which was an introduced species in "ancient" times, rather than being a modern introduction. Those arriving after are called neophytes.
Pennantia is the sole genus in the plant family Pennantiaceae. In older classifications, it was placed in the family Icacinaceae. Most authorities have recognised three or four species, depending on whether they recognised Pennantia baylisiana as a separate species from Pennantia endlicheri. British-born botanist David Mabberley has recognised two species.
Eustrephus is a monotypic genus in the family Asparagaceae, subfamily Lomandroideae. The sole species is Eustrephus latifolius, commonly known as wombat berry. It is an evergreen vine native to Malesia, the Pacific Islands and eastern Australia. It grows in sclerophyll forest, woodland, heathlands, shrublands, gallery forest and rainforests.
Melastoma denticulatum is a species of flowering plant in the family Melastomataceae, native from the Solomon Islands to the south Pacific.
Allophylus cobbe, commonly known as titberry or Indian allophylus, is a pantropical, shrub in the family Sapindaceae with many uses in traditional medicine. It has a highly variable morphology throughout its range and may prove to be more than one species.
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.
Pterolepis is a genus of flowering plant in the family Melastomataceae. Within Melastomataceae, it forms a clade with genus Pterogastra. Pterolepis contains some fifteen species, all of which are found in the Neotropical geographic realmm. Most species are concentrated in Brazil, with a few others across Central and South America.
Pseuduvaria froggattii is a rare species of tree which is restricted to a very small part of northeastern Queensland, Australia. It is a member of the custard apple and soursop family Annonaceae, and was first described in 1887. Despite the small range its status considered to be least concern.
