Flowering branches lateral or axillary, up to 10 (-16) cm long, with few leaves, inflorescences simple and umbellate or cymose, principal rays 2-4 cm long, pedicels 0.5-1 cm long, elongating in fruit; sepals oblong-ovate to lanceolate, ca. 1.5 mm long, glabrous, sparsely glandular punctate; corolla lobes white or pinkish, ovate, glandular punctate. Drupes dark red, globose, 5-8 mm in diameter, glandular punctate" (Wagner et al., 1999; p. 932).

Control: 

Physical:  "Seedlings and saplings can be hand pulled if soil disturbance is not a problem".

Chemical:  "Glyphosate can be used to spray dense seedling populations.  Larger trees are cut and the stumps treated with herbicide, or treated with a basal bark application of triclopyr"  (Weber, 2003; p. 53).
