Litsea longistaminata (Liou) Kosterm.


Description from Flora of China

Litsea garrettii Gamble var. longistaminata H. Liu, Laurac. Chine & Indochine, 196. 1934; L. longistaminata var. pubescens H. P. Tsui.

Evergreen trees, up to 10 m tall, ca. 20 cm d.b.h. Branchlets yellow-brown or ferruginous tomentose. Leaves alternate; petiole 1-2 cm, densely ferruginous tomentose; leaf blade obovate to obovate-oblong, 15-25 × 4.6-11.5 cm, pubescent and becoming glabrous abaxially, glabrous adaxially, pinninerved, lateral veins 7-9 pairs, base cuneate or obtuse, apex rounded and with abrupt acumen or acuminate. Umbels 4-6 in racemes on short branchlets, 5- or 6-flowered; peduncle ca. 1 cm, ferruginous. Male flowers: pedicel 2.5-3 mm; perianth segments 6, oblong or ovate-rounded; fertile stamens 9, ca. 7 mm, exserted; filaments pubescent, of 3rd whorls each with 2 stipitate small glands at base; rudimentary pistil small, glabrous. Fruit oblong, ca. 17 × 8 mm, apiculate at apex, seated on discoid perianth tube; fruiting pedicel 3-4 mm, pubescent. Fl. Dec-Jan, fr. Jun-Jul.

Litsea dunniana H. Léveillé (Repert. Spec. Nov. Regni Veg. 9: 460. 1911) was described from Guizhou and characterized by its sessile inflorescence, long-exserted stamens, and large oblong-lanceolate pinninerved leaves, covered abaxially with long slightly villous hairs. Allen (Ann. Missouri Bot. Gard. 25: 388, 391. 1938) considered Léveillé’s taxon to be similar to L. garrettii var. longistaminata, but the present authors could not ascertain its status because they have seen no material.

Open mountain slopes, valleys, thickets, mixed forests; 800-2000 m. SE Xizang, S Yunnan [Vietnam].
