Overview of Berberidopsidaceae: Flora of Eastern Australia and Chile

The Berberidopsidaceae family comprises two genera and three species, with two found in Eastern Australia and one in Chile. These scandescent shrubs or lianas are notable for containing cyanogenic glycosides. The leaves are alternate, simple, and can be entire to coarsely dentate. Their flowers, typically bisexual, display either a cyclic or acyclic structure with varying numbers of tepals and stamens. The fruit is a berry with a persistent style, found in montane rainforests and shaded coastal areas. This family is part of the diverse Flacourtiaceae family and is studied for its unique characteristics.

  1. BERBERIDOPSIDACEAE • 2 genera, 3 species; 2 spp. in E Australia, 1 sp. in Chile. • Scandent shurbs or lianas, often with cyanogenic glycosides. • Leaves alternate, simple, entire to coarsely dentate, sub-3-5-veined from the base, in 1 sp. glaucous. Stipules absent. • Flowers bisexual (always?), hypogynous, axillary, solitary or in many-flowered racemes or leafy racemes. • Flowers cyclic (5 sepals + 5 deciduous, pale pink to cream petals: Streptothamnus) or acyclic (13-17 deciduous, pink to purple tepals in a spiral: Berberidopsis). • Stamens 6-13 with very short filaments and muriculate anthers (Berberidopsis) or numerous with filaments longer than smooth anthers (Streptothamnus); disk present or absent; pollen 3-colpate. • Ovary unilocular, with 3-5 parietal placentae. • Fruit a berry with a persistent style.

  2. SPECIES OF BERBERIDOPSIDACEAE • Streptothamnus moorei F.v.Muell.: AUSTRALIA: Queensland & New South Wales; montane rainforests and edges of secondary vegetation. • Berberidopsis beckleri (F.v.Muell.) Veldk.: AUSTRALIA: Queensland & New South Wales; montane rainforest and edges of secondary vegetation. • Berberidopsis corallina Hook.f.: CHILE: Concepción, Arauco, Cautín, Valdivia, & Osorno; coastal cordilleras, banks of streams in dense shaded places.
