Botany
Tigau is a shrub, 2 to 4 meters high. Young branches, inflorescences, petioles, and lower surface of the leaves are densely covered with short, grayish or whitish, stellately arranged hairs. Leaves are oblong-ovate, 6 to 14 centimeters long, 2.5 to 5 centimeters wide, sharply toothed at the margin, and pointed at both ends. Cymes are short-stalked, borne in the axils of the leaves, and 2 to 4 centimeters long. Flowers are pale purplish or lavender, and about 3 millimeters long. Fruit is fleshy, pale lavender, rounded and 4 to 5 millimeters in diameter.

C. cana differs from C. americana in having stems and leaf undersides more tomentose, and especially in the racemes being more lax, the berries in the latter crowded together to look like one fruit.
