An upright, spindly shrub growing to 4 metres, though usually < 2 metres. Leaves are long and linear or slightly rounded. Leaf margins may be wavy or finely toothed. Male and female flowers are carried on separate plants; both are inconspicuous. More noticeable are the large clusters of waxy (and later papery) fruits. These may turn red but seem to remain whitish or pale brown in local populations. Each fruit capsule contains several dark, round seeds.
