Description

Bertya gummifera is a sticky shrub, growing from 1–2 m high.[4] The young growth is covered long whitish hairs, which sometimes persist on the stems, but most of the plant loses these and becomes rough and hairless with age.[4] The rough-surfaced leaves are 10–50 mm long and about 2 mm wide, and have margins which are rolled downwards from the upper surface (revolute). The flowers (with and without stalks) are crowded, and have 5-8 bracts. The male flowers have triangular outer bracts which are shorter and less broad than the inner bracts and the perianth segments are about 4 mm long and a reddish brown. The female flowers have narrower bracts, and their perianth segments enlarge and enclose the fruit.

The capsule is up to 12 mm long and about 7 mm in diameter.[4] The species was first described as Bertya gummifera by the botanist Jules Émile Planchon in 1845.[1][2]
