Authors: Xi-wen Li, Jie Li & Henk van der Werff

Evergreen trees or shrubs. Leaves papery to thickly leathery, pinninerved, ± pubescent. Cymose panicle axillary or subterminal, composed of pedunculate cymes or rarely subumbels, bracteate and bracteolate. Flowers bisexual, pedicellate. Perianth tube short; perianth lobes 6, subequal or outer 3 smaller, hairy, dilated after anthesis, caducous or persistent. Fertile stamens 9, in 3 whorls; filaments filiform, complanate, pilose, those of 3rd whorl each with 2 glands at base, others glandless; anthers 4-celled, cells introrse in 1st and 2nd whorls, all extrorse or upper 2 cells lateral and lower 2 cells extrorse in 3rd whorl. Staminodes 3, of innermost whorl, sagittate-cordate, stalked; stalk pilose. Ovary ovoid; style slender, hairy; stigma discoid. Drupe fleshy, small and globose, or large and ovoid or pear-shaped; fruit stalk ± dilated and fleshy, or terete.

Shrubs to medium-sized trees , evergreen. Bark reddish brown, thin, fissured. Leaves alternate, aromatic. Leaf blade pinnately veined; surfaces pubescent, especially abaxially, becoming glabrescent with age; domatia absent. Inflorescence appearing when mature leaves are present, axillary, flowers in pedunculate, compound cymes. Flowers bisexual; tepals persistent, yellowish, pubescent, outer tepals slightly shorter than inner; stamens 9, anthers 4-locular, 4-valved, anthers of outer 6 stamens introrse, anthers of inner 3 latrorse; staminodes 3, sagittate; ovary nearly globose. Drupe dark blue to black, nearly globose, borne on pedicel with tepals persistent at base; cupule absent. x = 12.

Species ca. 150 (3 in the flora): tropical and subtropical regions, Western Hemisphere.

Persea americana Miller, the avocado of commerce, with large, fleshy fruits and deciduous tepals, is widely grown in California and Florida. It may persist after cultivation.

Pubescence type and density are the most reliable characteristics in identifying species and are best seen on young leaves and branches.
