The green elliptical-ovoid to diamond-shaped , 4 - 15 cm long and 2 - 6 cm wide leaves have a short point at the top. The stem leaves are 2.5 - 4 mm long.

The flowers are at the top of the stem in an unflustered plume . The male flowers are at the top of the plume and usually have five stamens . The style of the female flower has three stamps . The 1.3 - 1.8 mm egg-shaped, flattened fruit is a non-popping, single-seeded nut that is shorter than the flower tops. The wrinkled lid is sturdy and ribbed. The black to dark red-brown, smooth, 1 - 1.3 mm seeds are ovoid and shiny. At the bark dairies , the 1.5 - 2.5 mm long fruit bursts.
