Auranticarpa is a genus of trees in the family Pittosporaceae. All six species occur in monsoonal forest and rainforest margins in Northern Australia. The species, all formerly included in the genus Pittosporum, are as follows: Auranticarpa edentata L.Cayzer, Crisp & I.Telford Auranticarpa ilicifolia L.Cayzer, Crisp & I.Telford Auranticarpa melanosperma (F.Muell.) L.Cayzer, Crisp & I.Telford Auranticarpa papyracea L.Cayzer, Crisp & I.Telford Auranticarpa resinosa (Domin) L.Cayzer, Crisp & I.Telford Auranticarpa rhombifolia (A.Cunn. ex Hook.)

Auranticarpa rhombifolia is a rainforest tree of eastern Australia. Known as the diamond leaf pittosporum, this tree is planted in many parts of Australia as an ornamental. The white flowers and orange fruit make it a most appealing street or garden tree. Other common names include hollywood, diamond leaf laurel, white myrtle and white holly. Australian botanists examined the large genus Pittosporum in 2000 and decided the more northerly examples are significantly different from those in the south. Subsequently, a new genus was created Auranticarpa, which means "gold fruit". The range of

Pittosporum multiflorum, known as the orange thorn, is a shrub growing in eastern Australia. The dense foliage provides a habitat for small birds and animals. It grows on shales or volcanic soils, from Eden, New South Wales north to Queensland, usually in or near rainforest areas.

Pittosporum spinescens is a shrub native to woodlands and dry rainforest of Northern and Eastern Australia and New Guinea. Growing to 7m tall with small leaves clustered on short branches that often terminate in a sharp point. The plant produced edible fruits, 2–3 cm in diameter. It is commonly known as wallaby apple, orange thorn or thorn orange. P. spinescens is very similar in appearance to the closely related Pittosporum multiflorum, but is readily distinguished by its entire leaf margins, in contrast to the toothed leaf margins of the latter.

Marianthus mollis, commonly known as hairy-fruited billardiera, is a species of flowering plant in the family Pittosporaceae and is endemic to a small region in the southwest of Western Australia. It is an erect, spreading, silky-hairy shrub with sessile, egg-shaped leaves and purplish-blue flowers arranged singly in leaf axils.

Bursaria reevesii is a species of flowering plant in the family Pittosporaceae and is endemic to a few places near Marlborough in Queensland. It is an erect or sprawling shrub with spiny side-shoots, egg-shaped adult leaves with the narrower end towards the base, flowers with five white petals, and rounded fruit.

Billardiera venusta is a species of flowering plant in the family Pittosporaceae and is endemic to the southwest of Western Australia. It is a woody climber or shrub with clustered sessile, hooked leaves and groups of four to six pale lilac flowers that fade to yellow as they age.

Billardiera rubens is a species of flowering plant in the family Pittosporaceae and is endemic to eastern Australia. It is a vigorous climber that has narrowly egg-shaped leaves and pendent yellow flowers with a reddish tinge on the edges.

Billardiera heterophylla (formerly Sollya heterophylla) is a species of flowering plant in the family Pittosporaceae, known by the common name bluebell creeper. It is native to Western Australia, but is grown as an ornamental plant in appropriate climates worldwide. It can sometimes be found growing in the wild as an introduced species or garden escapee, for example in other Australian states, in California, where it is popular in landscaping, and in Portugal, including Tapada de Monserrate, Sintra, and Madeira Island. It is sometimes considered a weed.

Billardiera drummondii is a species of flowering plant in the family Pittosporaceae and is endemic to the south-west of Western Australia. It is a slender climber that has linear leaves and tiny nodding, blue or mauve flowers arranged in groups of up to three.

Rhytidosporum inconspicuum (common name alpine appleberry) is an inconspicuous, rhizomatous specios of shrub in the pittosporum family, Pittosporaceae. The species is found in New South Wales, Victoria and Tasmania. The species was first formally described in 1999 by Lindy Cayzer, Michael Crisp and Ian Telford, when they published a revision of the genus, Rhytidosporum. The species epithet, inconspicuum, was given because the plant is inconspicuous when not in flower or fruit.

Pittosporum lancifolium, commonly known as narrow-leaved orange thorn or sticky orange thorn, is a species of flowering plant in the family Pittosporaceae and is endemic to eastern Australia. It is an erect shrub or small tree with narrowly egg-shaped to elliptic or broadly lance-shaped leaves, sessile flowers arranged singly or in pairs in leaf axils and spherical capsules.

Billardiera viridiflora is a species of flowering plant in the family Pittosporaceae and is endemic to a small area in the north-west of Tasmania. It is a twining shrub that has narrowly elliptic leaves and pendent greenish yellow flowers that turn a deeper yellow as they age.

Billardiera nesophila is a species of flowering plant in the family Pittosporaceae and is endemic to Tasmania. It is a slender, twining shrub that has narrowly elliptic leaves and pendent yellowish-green flowers that turn canary yellow as they age.

Bursaria calcicola is a species of flowering plant in the family Pittosporaceae and is endemic to a restricted area near Wombeyan Caves in New South Wales. It is a spiny, hairy, erect or sprawling shrub with clustered, narrowly elliptic to egg-shaped leaves, white flowers with triangular sepals, cream-coloured petals and flattened fruit.

Marianthus sylvaticus is a species of flowering plant in the family Pittosporaceae and is endemic to a small area in the southwest of Western Australia. It is a slender climber with clustered, toothed, linear leaves and blue and white flowers with purple veins.

Marianthus paralius is a species of flowering plant in the family Pittosporaceae and is endemic to a restricted part of the southwest of Western Australia. It is a more or less prostrate shrub with thick, egg-shaped leaves and red flowers.

Marianthus dryandra is a species of flowering plant in the family Pittosporaceae and is endemic to a restricted area in the southwest of Western Australia. It is an erect, straggling shrub with densely hairy new shoots, stem-clasping, egg-shaped leaves and cream-coloured flowers with maroon spots, arranged on short side shoots.
