Genus

Angiosperms > Laurales > Atherospermataceae

Characteristics

Tall trees, young branches ± tetragenous usually glabrous. Leaves dentate or almost entire. Inflorescence axillary, of dichasia or few-flowered pleiochasia, bracteoles broad enclosing the flowerbud, early caducous. Flowers bisexual, perianth and androecium on the rim of the hypanthium; tepals 8, in 2 whorls, oblong-elliptic, obtuse. Androecium tetramerous, the outer 1—2 whorls of stamens with divergent ovate-deltate, planate to shallowly cupular, obtuse staminal glands and shortly apiculate to broadly rostrate, latrorsely to ± ex-trorsely dehiscing anthers, the inner whorls of lanceolate-deltoid to almost sub-ulate staminodes. Gynoecium of several free carpels, styles terminal; ovule subbasal. Fruiting hypanthium cylindrical-ellipsoid, dehiscing into 4 (sometimes 2) equal valves. Nutlets narrowly ellipsoid to obclavate, silky hirsute on one side in deep pits, styles terminal, subulate.

Tall trees, usually ± glabrous. Leaves dentate to almost entire. Inflorescences axillary, narrow thyrsoid panicles, usually 3–5-flowered; bracts small, caducous before anthesis. Flowers bisexual. Hypanthium ovoid to shortly campanulate. Perianth of 8 tepals in 2 whorls. Androecium of 4 whorls; outer (1 or 2) whorls each of 4 stamens, each with 2 short appendages (glands) at base of filament; connective shortly prolonged above anthers; inner (2 or 3) whorls each of 4 staminodes. Carpels usually 8–16; styles terminal. Fruiting hypanthium enlarged, ellipsoid to cylindrical, glabrous, dehiscent regularly into 4, sometimes 2, equal valves; perianth not persistent; staminodes sometimes persistent.
