Opened fruit

Flindersia pimenteliana, commonly known as maple silkwood, red beech or rose silkwood, is a species of tree in the family Rutaceae and is native to New Guinea and Queensland. It has pinnate leaves with three to seven egg-shaped to elliptic leaflets, panicles of red or reddish flowers and fruit studded with rough points.

Description

Flindersia pimenteliana is a tree that typically grows to a height of Шаблон:Cvt. It has pinnate leaves Шаблон:Cvt long arranged in more or less opposite pairs with three to seven, egg-shaped to elliptic leaflets Шаблон:Cvt long and Шаблон:Cvt wide. The side leaflets are on a petiolule Шаблон:Cvt long and the end leaflet on a petiolule Шаблон:Cvt long. The flowers are arranged in panicles Шаблон:Cvt long, the five sepals about Шаблон:Cvt long and the five petals red or reddish and Шаблон:Cvt long. Flowering occurs from November to February and the fruit is a woody capsule Шаблон:Cvt long and studded with rough points up to Шаблон:Cvt long. The fruit opens into five valves, releasing winged seeds Шаблон:Cvt long.

Taxonomy

Flindersia pimenteliana was first formally described in 1875 by Ferdinand von Mueller in Fragmenta phytographiae Australiae from specimens collected near Rockingham Bay by John Dallachy.

Distribution and habitat

Maple silkwood grows in rainforest in Australia and New Guinea. In Australia in grows at altitudes from Шаблон:Cvt and is found from Mount Finnigan in Ngalba Bulal (Cedar Bay) National Park) south to Paluma Range National Park near Townsville.

Uses

Good quality, decorative cabinet timber has been produced by this tree but because it is mostly only found in reserves, the timber is in very short supply. Attempts to grow this species in plantations have failed.

Chemical constituents

F. pimenteliana contains tryptamine alkaloids known as pimentelamines. They are adducts of ascorbic acid. The plant also contains 2-isoprenyl-N,N-dimethyltryptamine, another tryptamine alkaloid, as well as 4-methylborreverine, borreverine, dimethylisoborreverine, quercitrin, and carpachromene.
