[1] The thin, deciduous leaves are generally oval in shape, green to grayish in color, and up to 6 centimetres (2+1⁄2 in) long. [1] The edges are smooth or faintly toothed. The inflorescence is an umbel of up to 15 flowers with five pointed sepals opening into a starlike shape and five smaller, greenish petals. [1] The fruit is a drupe which ripens to black. It measures just over 1 cm long and contains 2 seeds.
