Capparis arborea is a bush or small tree occurring in eastern Australia. Its habitat is rainforest, usually riverine, littoral or the drier rainforests. It is distributed from the Hunter River, New South Wales to Cape Melville in tropical Queensland. Common names include native pomegranate, wild lime, wild lemon and brush caper berry. Capparis arborea is a host plant for the Belenois java, which migrate across the eastern seaboard in large numbers in the summer. It also feeds the Elodina parthia
Leaves alternate on the stem, and are simple, oblong-lanceolate or sometimes oblong-ovate in shape. They are 5 to 10 cm long, and 1.5 to 5 cm wide, and mostly rounded at the tip, although some leaves are pointed at the tip. Juvenile leaves are smaller than adult leaves with a prickly pointed leaf tip. Leaf veins are visible on both surfaces with the midrib raised under the leaf, but sunken on top of the leaf.
From December to March, a fruit resembling a guava forms. It is green, smooth and soft, globular in shape and 2.5 to 6 cm in diameter. The fruit stalks are 3 to 5 cm long. The seeds are round and flattened, and 8 to 10 mm in diameter. The ripe fruit are yellow with the pulp surrounding the seeds being edible. They were a source of food for Aboriginal people. Germination from fresh seed is not particularly difficult, with the first seeds germinating after three weeks.
