Arenga australasica, commonly known as arenga palm or southern arenga, is a plant in the palm family Arecaceae found only in the Northern Territory and Queensland, Australia. It has a clustering habit and it may reach 20 m (66 ft) in height with a trunk diameter of 30 cm (12 in). Fronds can be up to 4 m (13 ft) long with numerous leaflets (often more than 100), dark green above and grey underneath. Inflorescences are produced from the bases of the fronds and can reach a length of 2 m (6 ft 7 in), carrying numerous pendant panicles of flowers. The flowers are in clusters of 3 with one pistillate (functionally female) and two staminate (functionally male) flowers. The red or purple fruit are almost spherical in shape, about 28 mm (1.1 in) diameter and contain two or three seeds.[4][5]
The species was first described in 1875 as Saguerus australasicus by botanists Hermann Wendland and Carl Georg Oscar Drude, and then later transferred to the current binomial by Stanley Thatcher Blake and Carl Georg Oscar Drude in 1963.[3]
