Ceratopetalum gummiferum

Ceratopetalum is a genus of nine species of shrub and tree in the family Cunoniaceae. They are found along the eastern coast of Australia and extend north to New Guinea. Two Australian species are among the best known, one being C. apetalum or coachwood, renowned as a timber tree, and C. gummiferum, the New South Wales Christmas bush.

Contents

Both New South Wales Christmas bush (C. gummiferum) and coachwood (C. apetalum) are widespread from south-east Queensland to the south coast of New South Wales, whereas the other extant Australian species are largely confined to high-altitude montane habitats in north-east Australia. These restricted distributions have been hypothesised to be refugia from cycles of changing climate during the Pleistocene. [2]

Species

Fossil evidence

Fossil evidence for Ceratopetalum species has been found in Eocene deposits in South Australia. [4] Named fossil species include Ceratopetalum maslinensis and Ceratopetalum westermannii.

Cunoniaceae is a family of 27 genera and about 335 species of woody plants in the order Oxalidales, mostly found in the tropical and wet temperate regions of the Southern Hemisphere. The greatest diversity of genera are in Australia and Tasmania, New Guinea, and New Caledonia. The family is also present in Central America, South America, the Caribbean, Malesia, the islands of the South Pacific, Madagascar and surrounding islands. the family is absent from mainland Asia except from Peninsular Malaysia, and almost absent from mainland Africa apart from two species from Southern Africa. Several of the genera have remarkable disjunct ranges, found on more than one continent, e.g. Cunonia, EucryphiaWeinmannia.

Prostanthera lasianthos, commonly known as the Victorian Christmas bush or coranderrk , is a large shrub or small tree of the mint family, Lamiaceae, which is native to Queensland, New South Wales, Victoria and Tasmania in Australia. It grows up to 10 m (35 ft) high but is usually much less and is found in wet sclerophyll forests, often beside creeks. Its flowers, which appear in profuse sprays, are about 2 cm long and white or pale lilac, with purple and orange blotches in the throat. They appear in late spring and summer, and specifically around Christmas time in Victoria. The fragrant, toothed leaves are 4 to 12 cm long and about 1.5 cm wide.
