[Shrub], tree, [parasitic vine], generally evergreen, aromatic; [dioecious or ± so]. Leaf: generally alternate, simple, unlobed [(lobed)], entire, generally thick; stipules 0. Inflorescence: [(flowers 1, head), raceme, panicle], umbel-like, enclosed by bracts [or not]. Flower: generally bisexual, generally ± yellow to ± green; hypanthium often calyx-tube-like, perianth parts in 2(3) whorls of 3, ± sepal-like; stamens [(3)]9[(12)], in whorls of 3, inner often with 2 stalked orange glands at base, 1 [or more] whorls often staminodes [or not], anthers  4-celled, opening by uplifting valves; pistil 1, simple, ovary generally superior, chamber 1, ovule 1, style 1, very short. Fruit: ± berry, often with swollen hypanthium, sepals.
± 54 genera, ± 3500 species: widespread in tropics, less so in temperate; some cultivated (Laurus, laurel, bay; Persea, avocado; Cinnamomum, cinnamon, camphor).

Key to Lauraceae
Inflorescence: terminal or in leaf axils, panicle-like cyme. Flower: perianth parts 6; stamens 9, anthers 4-celled.
± 100 (± 200 if Asian species included) species: tropics, subtropical America; cultivated for avocado. (Ancient name for an Egyptian tree)
Unabridged etymology: (Name used by Theophrastus for an Egyptian tree)
Stem: < 30 m. Leaf: 6–25 cm, 3–11 cm wide, narrow- to wide-elliptic, hairs 0 to sparse abaxially, 0 adaxially; basal pair of lateral veins as strong as distal, without axillary pit; petiole < blade. Inflorescence: in distal leaf axils, 5–15 cm. Flower: perianth parts 4–6 mm, ovate, hairy; staminodes small; pistil hairy. Fruit: pear-shaped or round, 5–15 cm, yellow-green to dark purple.
2n=24. Disturbed areas, abandoned gardens; < 580 m. South Coast; native to mountains of Central America, widely cultivated for fruits. Unlikely to escape cultivation areas due to large, heavy seeds. Mar–May [Online Interchange]
