Archontophoenix maxima, the Walsh River palm, is the largest species of the genus Archontophoenix. It is endemic to Queensland, Australia.[3][4] 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]
Description

The Walsh River palm grows up to 25 m (82 ft) metres tall, with a trunk up to 30 cm (12 in) in diameter with an expanded base. The rigidly-held, erect leaves are up to 4 m (13 ft) long, and have a slight sideways twist. The massive branched inflorescence is up to 1.5 m (5 ft) long, and bear 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.
