Elaeocarpus arnhemicus, commonly known as elaeocarpus,[1] blue plum, bony quandony or Arnhem Land quandong,[2] is species of flowering plant in the family Elaeocarpaceae and is native to northern Australia, New Guinea, Timor and certain other islands in the Indonesian Archipelago. It is a tree with narrow elliptic to lance-shaped or egg-shaped leaves with serrated edges, racemes of white or cream-coloured flowers and metallic blue fruit.

Description

Elaeocarpus arnhemicus is a tree. Although it was once believed to often grow as a shrub and only grow to a height of Шаблон:Cvt with a DBH of up to Шаблон:Cvt,[1][2][3][4] it is now known that it can become a much larger plant, to 40m high.[5]

The leaves are narrow elliptic to lance-shaped or egg-shaped, Шаблон:Cvt long and Шаблон:Cvt wide with serrations on the edges, on a petiole Шаблон:Cvt long. The flowers are arranged in racemes up to Шаблон:Cvt long, each flower on a pedicel up to Шаблон:Cvt long. The sepals are ovate, Шаблон:Cvt long and Шаблон:Cvt wide. The petals are obovate, white or cream-coloured, Шаблон:Cvt long and Шаблон:Cvt wide, the tip with 7-12 linear lobes. Both the petals and sepals are usually only Шаблон:Cvt long. There are between fifteen and eighteen, sometimes up to twenty, stamens and the style is Шаблон:Cvt long and glabrous. Flowering occurs from January to July and the fruit is an elliptical, metallic blue drupe Шаблон:Cvt long and Шаблон:Cvt wide.[1][2][3][5]

This species is best identified among other Elaeocarpus species when in flower.[5]

Taxonomy and naming

Elaeocarpus arnhemicus was first formally described in 1868 by Ferdinand von Mueller in his book Fragmenta Phytographiae Australiae.[6][7]

It is placed in the Fissipetalum group of Elaeocarpus species.[5]

Distribution and habitat

Blue plum grows in riparian rainforest and some other habitats in the northern part of the Northern Territory, Cape York Peninsula, north-east Queensland and New Guinea at altitudes up to Шаблон:Cvt above sea level.[1][2][3][4] In 2001 the known range was expanded to Java, Timor, Flores, Sumba and Sulawesi. After receiving some new specimens, M. J. E. Coode, expert Elaeocarpus taxonomist, realised that a few old specimens from two collection localities that he and his colleague Raymond Weibel had never been able to identify, were actually E. arnhemicus, considerably expanding its range.[5]
