Amyema plicatula is a species of hemi-parasitic shrub found in the Bismarck Archipelago, New Guinea, New South Wales[4] and Queensland.[5][6]
Description
It is an aeria,l stem-parasitic shrub, with short epicortical runners. The leaves, which are usually opposite, are elliptic to obovate, and about 5.5-11 cm by 3-8 cm, with no obvious venation. They sometimes occur in whorls of 3 to 4, on short stalks which are 0.4-0.8 cm long.[7]
The flowers occur in umbels. The primary stalk of the inflorescence is about 12-20 mm long, with the stalks in the umbels being about 5-10 mm long. The flowers in their diads or triads are stalkless. The calyx lobes are inconspicuous or non-existent. The corolla lobes are red, and about 20-23 mm by 8-10 mm. The anthers are about 3 mm long on anther filaments which are about 8 mm long. The style is about 20 mm long.[7]
The ovary is about 2-3 mm long, and the fruits are ellipsoid to obovoid, about 7-10 mm long, and the calyx limb and style often persists at the apex of the fruit.[7]
Distribution
In New South Wales it is found in remnant rainforests of the North Coast.[6] In Queensland it is known from just one collection in the north east[7] Outside Australia it has been found in rainforests and open humid forests from sea level to 1600 metres.[6]
Taxonomy
Amyema plicatula is member of the Santalales, the mistletoe order, placed within the family Loranthaceae. It was first described as Loranthus plicatulus by Kurt Krause from a specimen collected in New Guinea,[8][9] but was transferred from the genus Loranthus in 1929 by Danser.[3]
The genus name, Amyema, is derived from Greek for 'without' and 'to instruct'.[10]
Host plants
Downey records just one host, Dysoxylum fraseranum, in the Meliaceae family.[11]
