Archontophoenix maxima, commonly known as the Walsh River palm or Oaky Creek Archontophoenix, is a large tree of the palm family Arecaceae. It is endemic to Queensland, Australia, and was first described in 1992.

Description

Juvenile A. maxima

The Walsh River palm grows up to 22 m (70 ft) tall; the trunk is up to 30 cm (12 in) and has an expanded base. The erect to horizontal fronds are up to 4 m (13 ft) long, and are slightly rotated around the long axis. The massive branched inflorescence is up to 1.5 m (5 ft) long and bears white flowers. When ripe, the fruit is red and 13–15 mm (0.5–0.6 in) in length. The flowers closely resemble those of A. alexandrae.[4][5]

Distribution and habitat

This robust palm grows in rainforest at altitudes between 800 and 1,200 m (2,600 and 3,900 ft) on the Walsh River and the adjacent Mount Haig Range in the Atherton Tablelands at approximately 17° South latitude.[4]
