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]

"Large shrub or small tree, twigs minutely pubescent. Leaves coriaceous, lustrous above, pubescent beneath, at least on the midrib, evergreen, elliptic to obovate to oblanceolate or lanceolate, 2-10 cm long, 0.3-3 cm wide, remotely serrulate, serrate, or entire, often revolute. Pedicels usually densely canescent. Staminate flowers in short, axillary compound cymes, 4-merous. Pistillate flowers solitary or in 3-flowered, pedunculate cymes, in the leaf axils or from nodes just below the leaves; 4-merous. Drupe red, occasionally yellow or orange, lustrous, globose, 5-8 mm in diam.; pyrenes 4, irregularly grooved on the back, 4-5 mm long." [1]
