The leaves are ovate or ovate lanceolate and measure 3.5 to 11 cm long by 1.5 to 6 cm wide. The leaf tip is pointed and the leaf base is rounded or truncate. The leaf stalk is 1.5 to 4 cm long. The upper leaf surface is shining green and the lower leaf surface is paler and duller. The flowers are grouped in clusters comprising of one stalkless female and two short, stalked male flowers. Each flower cluster has four or five bracts and a stalk 1.5 to 9 cm long. The female flowers have ten perianth segments, the male flowers eight.
