Pritchardia munroi, a member of the Arecaceae (palm) family, is a tree 4 to 5 m (13 to 16 ft) tall with a trunk up to 20 cm (7.8 in) in diameter. The leaf blade is 88 cm (35 in) long with a petiole 85 cm (33 in) long. The leaves and petioles have scattered, mostly deciduous scales and hairs, somewhat larger on the lower leaf ribs. The leaves are deeply divided into segments which have long, drooping tips. Numerous bisexual or functionally male flowers are arranged in clusters on hairy, branching stalks about 52 cm (20 in) long which originate at the leaf bases. The flower consists of a cup-shaped, three-lobed calyx; three petals; six stamens; and a three-lobed stigma. The mature fruit is shiny, black, nearly spherical, and 2 cm (0.8 in) in diameter.
