Ptychosperma macarthurii, commonly known as the Macarthur palm, is a species of tree in the palm family Arecaceae. Its native range is northern Cape York Peninsula in Queensland with a number of disjunct populations in the Northern Territory and New Guinea. The species has been widely planted in tropical areas and is commonly grown as an indoor plant.

Description

P. macarthurii is a clumping (multi-stemmed) palm growing to a height of 10 m (33 ft). The slender stems measure up to 10 cm (3.9 in) in diameter and have prominent leaf scars encircling the trunk. They are green in the younger sections of the trunk just below the crownshaft, but may be greyish lower down.

The crown consists of between 3 to 13 paripinnate fronds to 3 m (9.8 ft) in length, with 15-40 pinnae (leaflets) on either side of the rachis (midrib), and have a crownshaft which measures about 70 cm (28 in) long.

The leaflets measure up to 56 cm (22 in) in length, are regularly or irregularly arranged (often clustered), with nearly parallel margins and a truncated tip. They are mid green on the upper surface and lighter below.

The inflorescences are up to 45 cm (18 in) long and branched 2 to 3 times. Flowers are grouped in sets of 3, each with one pistillate (functionally female) set between two staminate (functionally male) flowers. They are yellow-green to light-green with 3 sepals and 3 petals; staminate flowers are 7 mm (0.28 in) long by 4 mm (0.16 in) wide with 23-40 stamens, pistilate flowers measure about 5 mm (0.20 in) and have 3-6 staminodes and a 0.5 mm (0.020 in) recurved stigma.

Fruits of Ptychosperma macarthurii measure up to 18 mm (0.71 in) long and 12 mm (0.47 in) wide, are bright red when ripe and the remains of the stigma is attached at one end. There is a thin layer of flesh around the solitary seed, which is about 12 mm (0.47 in) long with five deep longitudinal grooves.
