土楠 tu nan
Trees, up to 8 m tall. Bark gray. Branchlets brown, terete but ± angled and striate, glabrous but pubescent when young, warty. Leaves alternate; petiole 1-1.5 cm, concave-convex, glabrous; leaf blade greenish and opaque abaxially, green and shiny adaxially, lanceolate to oblong-elliptic, 9-15 × 3-6 cm, papery, glabrous and densely finely glandular-spotted on both surfaces, midrib elevated on both surfaces but rather conspicuous abaxially, lateral veins 6-8 pairs, slightly elevated abaxially, conspicuous adaxially, veins and veinlets reticulate, conspicuous and foveolate on both surfaces, base cuneate, always asymmetric on sides, apex acuminate with obtuse acumen or obtuse with acute acumen. Panicle axillary, 2-6 cm, few flowered, glabrate; peduncle up to 1 cm, slender, sparsely puberulent initially but soon glabrate. Pedicels slender, 3-10 mm, thickened after anthesis. Flowers yellowish, scented, ca. 3.5 mm, glabrous. Perianth lobes ovate, fleshy. Fertile stamens 3, triangular, ca. 2 mm, tightly adnate and nearly connate. Ovary ovoid, ca. 1 mm; style short; stigma capitate. Fruit narrowly ellipsoid when dry, up to 3.8 × 1.4 cm, purple-brown when mature, glabrous, obtuse at both ends; fruit stalk gray or black-red, ca. 5 × 2 mm, glabrous. Fl. Jun, fr. Sep.
● Mixed forests in valleys, thickets on open land; ca. 400 m. Hainan.
