Carrierea dunniana Leveille

The type specimen of Carrierea dunniana (Cavalerie 3001, Guizhou) at K includes both pistillate and staminate flowers.

Trees, 5-10 m tall; bark gray-brown; branchlets grayish, glabrous. Petiole 1-3 cm, slender, glabrous; leaf blade greenish abaxially, deep green adaxially, ovate to oblong, 7-12 × 3-5.5 cm, 2.2-2.8 × as long as broad (based on a small sample), thinly leathery, abaxially glabrous or sparsely tomentose along veins, adaxially glabrous, palmately 3-veined from base, lateral veins 4 or 5 pairs, base rounded, margin remotely serrate, apex broadly acute, contracting gradually or more abruptly to an acumen 1-2 cm. Inflorescence terminal, to ca. 10 cm, 8-15-flowered; rachis pubescent to tomentose, hairs spreading to semiappressed, whitish, short; bracts ovate, 5-7 mm, papery, both surfaces sparsely appressed hairy, with one or two small glands on margin at base, apex rounded. Pedicels 1.5-1.8 cm, 2(or 4)-bracteolate near middle; bracteoles similar to bracts, opposite or subopposite, broadly oblong, ovate, or elliptic, 2.5-5 mm, both surfaces sparsely appressed pubescent, scarcely or not glandular at margin near base. Sepals obovate to elliptic, 5-10 mm, both sides yellowish tomentose, base not or only slightly cordate when sepal erect, apex obtuse. Staminate flowers: stamens with filaments unequal, longest 3-5 mm, glabrous; anthers ca. 0.5 mm; pistillode very small. Pistillate flowers: staminodes like stamens but much reduced; ovary ovoid, ca. 4 mm, very densely yellowish pubescent, placentas 3; styles 3, very short (0.5-1 mm), connate at least at base to form a thick column, densely pubescent as ovary; stigmas strongly reflexed, drying black, 2-3 mm, flattened, narrowly triangular, bifurcate in distal half with branches irregularly lobed at apex, abaxially sparsely hairy, adaxially glabrous. Capsule fusiform, 2.5-4 cm. Fl. May-Jun, fr. Aug-Oct.
