: unlobed (unlobed or lobed
in Sassafras ), margins
entire, occasionally with domatia (crevices or hollows serving as lodging for mites
) in axils of main lateral

, or staminate and bisexual on some plants, pistillate and bisexual on others; flowers usually yellow to greenish or white, rarely reddish; hypanthium well developed, resembling calyx tube
, tepals and stamens perigynous; tepals 6(-9), in 2(-3) whorls of 3, sepaloid
, equal or rarely unequal, if unequal then usually outer 3 smaller than inner 3 (occasionally absent in Litsea ) ; stamens (3-) 9(-12), in whorls of 3, but 1 or more whorls frequently staminodial or absent; stamens of 3d whorl with 2 glands
2- or 4-locular, locules opening by valves
; pistil 1, 1-carpellate; ovary 1-locular; placentation basal; ovule 1; stigma subsessile
or capitate. Fruits drupes, drupe borne on pedicel with or without persistent
tepals at base, or seated in ± deeply cup-shaped receptacle (cupule), or enclosed in accrescent
. Seed 1; endosperm absent.
Genera ca. 50, species 2000-3000 (9 genera, 13 species in the flora ) : pantropical , a few species also in subtropical and temperate regions
Cassytha is sometimes placed in its own family , Cassythaceae; it is here retained in Lauraceae.

]. Leaves alternate, not aromatic
. Leaf blade
pinnately veined, rarely with 3 primary
veins, leathery; surfaces glabrous
or variously pubescent
; domatia absent. Inflorescences appearing with or before new leaves, axillary
, pseudoumbels, subtended by decussate bracts. Flowers unisexual
on different plants
; tepals deciduous, yellow, green, or white, equal, glabrous. Staminate flowers
: stamens 9 (or 12) ; anthers
4-locular, 4-valved, introrse
. Pistillate flowers: staminodes 9 (or 12) ; ovary globose
. Drupe red, globose, seated in small, single-rimmed cupule.
Species ca. 400: North America, Mexico, Central America, mostly in Asia.
Mexico has four species of Litsea, one of which extends to Costa Rica in Central America. Litsea merits revision and, as accepted here, it is probably polyphyletic. It is very similar to Lindera and best recognized by its 4-locular anthers (2-locular in Lindera ).
