Tetrastigma (Greek, four and stigma, in reference to the 4-lobed or 4-parted stigma). Vitaceae. About 40 species in Trop. and Subtrop. Asia of shrubs climbing by tendrils: lvs. alternate, digitate or pedate; lfts. 3-5, sometimes reduced to 1; tendrils with adhesive disks or twining: fls. polygamo-dioecious, in axillary cymes or umbels, 4-merous; petals spreading; disk adnate to the base of the ovary; stigma sessile, 4-lobed or 4-parted: berry 2-4-seeded; seeds ovoid-globose, sulcate on the inner surface. Allied to Cissus and Parthenocissus but easily distinguished by the sessile 4-lobed stigma and from the latter by the 4-merous fls. Of the numerous species only the following are occasionally cult.; T. obtectum and T. serrulatum are probably the hardiest, but tender in the N., and are graceful small-lvd. vines which may be used where vines of more delicate character are desired; the first species clings to walls, the second has twining tendrils. T. Harmandii is a tall-growing vine with larger lvs. and edible berries, suited only for tropical or subtropical countries. For cult. and prop., see Cissus and Parthenocissus. T. obtectum, Planch. (Cissus obtecta, Wall.). Climbing with disciferous tendrils: branchlets hirsute: lvs. long-stalked, persistent or subpersistent; petioles pubescent; lfts. 5, digitate, sessile, cuneate-obovate to elliptic, acute, remotely crenate-serrate with mucronate teeth, glabrous, or in var. pilosum, Gagnep., pubescent beneath, 1/2 – 1 1/2 in. long: fls. greenish, in slender-stalked umbels; pedicels slender: berries ovoid, 1/4 in. long. Himalayas, Cent. and W. China. T. serrulatum, Planch. (Cissus serrulate, Roxbg. Vitis capreolata, Don). Climbing with twining tendrils, glabrous: lfts. 5, pedate, sometimes 3, short-stalked, ovate or elliptic to elliptic-lanceolate, acute or acuminate, serrate, 1/2 – 2 1/2 in. long: fls. in compound cymes: fr. globose, black, 1/4 in. thick or slightly larger. Himalayas, W. China. T. Harmandii, Planch. High climbing with twining tendrils: lfts. 3-5, short-stalked, narrowly lanceolate, serrate, glabrous, about 2-3 in. long: fls. in axillary short-stalked cymes: fr. globose, 2-3-seeded. Philippine Isls. Recently intro. by the Dept. of Agric.; said to have edible berries similar to those of the Scuppernong grape. CH
