Description
“Trees or shrubs, usually with imperfect flowers. Leaves simple, entire, serrate, dentate or crenate; stipules obsolete. Flowers axillary, solitary, fascicled or in cymes, 4-7 merous, 4-8 mm broad; petals united at the base, imbricate in bud; pistillate flowers usually with nonfunctional stamens; anthers opening lengthwise; stigmas 4-7, essentially sessile. Drupe red, black or rarely yellow or white. Seeds with hard, bony endocarp (pyrenes), often grooved or ribbed on the back, 4-7 in a fruit, 1 in each locule.” [1]
"Rhizomatous shrub to 3m tall, usually forming extensive colonies, twigs puberulent. Leaves evergreen, obovate to elliptic, 2.5-6.5 cm long, crenate, but usually only toward the apex, the last pair of teeth usually directly opposite each other, glabrous, lustrous above; petioles 38 mm long, canescent. Pedicels 1-5 mm long, appearing longer when single fruited (careful examination shows that the lower part is peduncle). Staminate flowers in axillary, 3-7 flowered, pedunculate cymes. Pistillate flowers axillary, solitary or in 3-flowered, pedunculate cymes. Flowers 5-7 merous. Drupe black, dull or slightly lustrous, globose, 5-7 in diam.; pyrenes 5-7, smooth, 3-4 mm long." [1]
