Bertya gummifera
Bertya gummifera is a sticky shrub in the family Euphorbiaceae, endemic to New South Wales. It grows in woodland and often in sandstone areas. It flowers in spring. Description. "Bertya gummifera" is a sticky shrub, growing from 1–2 m high. 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. 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. The species was first described as "Bertya gummifera" by the botanist Jules Émile Planchon in 1845.
