Atractocarpus decorus is a plant in the coffee family Rubiaceae which is endemic to New Guinea. Like many others in the genus, it has glossy dark green leaves and attractive white flowers.
Description
Atractocarpus decorus is a large shrub or small tree growing up to 4 m (13 ft) high. It has large leaves arranged in opposite pairs on the twigs, measuring up to 32 cm (13 in) long by up to 13 cm (5.1 in) wide. They are glossy dark green above and lighter below with 9 to 13 prominent lateral veins each side of the midrib.[4] The female inflorescence consists of a single flower whereas the male inflorescence has between 15 and 30 flowers. Flowers are white with 5 petals, about 5 cm (2.0 in) long and 8 cm (3.1 in) across; the orange fruit is a solitary drupe about 4 cm (1.6 in) long and 3 cm (1.2 in) diameter.[4]
Taxonomy
The species was first described in 1925 as Randia decora by Theodoric Valeton, based on material collected across New Guinea by the German botanist Rudolf Schlechter and Swiss botanist Carl Ludwig Ledermann (fr) between 1901 and 1912.[5] In a major review of the genus Atractocarpus in 1999 by Christopher Puttock, this species was transferred to Atractocarpus.[4]
Distribution and habitat
This species is endemic to New Guinea,[2][3][4] and grows in numerous locations on the island at altitudes from near sea level to at least 800 m (2,600 ft).[3][5][6]
