Description

Livistona alfredii has cream flowers, flowers from July to September,[3] and fruits from December to May.[4] It is a dioecious palm, growing to 12 m, with prominent leaf scars.[4] The petioles of dead leaves persist for the first metre, but shed higher up the stem.[4] Fibres in the leaf-base are prominent, coarse, and persistent.[4] The leaves are pale green-grey to glaucous on the upper surface, and light green-grey and waxy and dull on the lower surface.[4] The inflorescences are unbranched at the base, and do not extend beyond the limit of the crown, but branch up to three orders.[4] The flowers are solitary or in pairs, cylindrical in bud with triangular sepals.[4]

Distribution

This palm is endemic to the north-west of Western Australia.[1] It has been found in Beard's Eremaean Province in the IBRA regions of Carnarvon and Pilbara, by the edges of permanent pools.[3]

Taxonomy

Livistona alfredii was first formally described by Ferdinand von Mueller in 1892.[2][5]
