Billardiera, commonly known as appleberries, snot berries, or bluebell creepers,[2] is a genus of flowering plants in the family, Pittosporaceae and is endemic to Australia. Plants in the genus Billardiera are woody scramblers, climbers or twiners with elliptic, lance-shaped or linear leaves arranged alternately along the stems, the flowers with petals that are joined to form a tube at the base with spreading lobes, and succulent or fleshy fruit.

Description
editPlants in the genus Billardiera are woody scramblers, climbers or undershrubs with twining branches up to several metres long. The leaves are simple, elliptic, lance-shaped or linear and arranged alternately along the stems. The flowers are arranged singly or in cymes on the ends of branches and are greenish-yellow to cream-coloured, purple or blue, the sepals free from each other. The five petals are much longer than the sepals, sometimes free from each other, or joined at the base to form a tube with spreading lobes. The stamens are free from each other, but sometimes have their anthers joined at the tip, encircling the style. The fruit is a succulent or fleshy, variously shaped berry containing many seeds.[2][3][4][5][6][7]
Taxonomy
editThe genus Billardiera was first formally described in 1793 by James Edward Smith in his book A Specimen of the Botany of New Holland, and the first species he described (the type species) was Billardiera scandens.[8][9] The name, Billardiera honours Jacques-Julien Houtou de Labillardière.[9]
