Tasmannia is a genus of about 36 species of flowering plants in the family Winteraceae, and is native to Australia and New Guinea, with one species (Tasmannia piperita) also found in parts of Southeast Asia. Plants in the genus Tasmannia are shrubs or small trees, usually dioecious with simple leaves, mostly white, sometimes yellow flowers, and one to many clusters of berries.
DescriptionEdit
Plants in the genus Tasmannia are shrubs or small trees that are usually dioecious, with simple, aromatic leaves arranged alternately along the branchlets, and have fine oil dots. There are no stipules. The flowers are usually white, sometimes yellow and arranged singly in the axils of bud scales, appearing like an umbel, later becoming like a whorl. The sepals are joined together, completely enclosing the flower bud, later splitting into lobes. The fruit is a berry arranged singly or in clusters of up to 6.<ref name="FoA">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="RGBV">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="RBGS">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
TaxonomyEdit
The genus Tasmannia was first formally described by published by Augustin Pyramus de Candolle in his Regni Vegetabilis Systema Naturale, from an unpublished description by Robert Brown (botanist, born 1773).<ref name=APNI>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="DC.">Template:Cite book</ref>
The genus name, Tasmannia honours the Dutch explorer Abel Tasman.<ref name="FoA" />
The taxonomic status of, and evolutionary relationship between Tasmannia and Drimys has been the subject of controversy for many years. A 2004 paper by Andrew Doust and Andrew Dinnan confirmed that the two genera do not form a monophyletic group, although they share distinctive similarities in their flowers.<ref name="AJB">Template:Cite journal</ref>

Distribution and habitatEdit
In Australia, the genus Tasmannia ranges from Tasmania and eastern Victoria and New South Wales to southeastern Queensland, and in the mountains of northeastern Queensland, where it grows in moist mountain forests and in wet areas in the drier forest and along watercourses to an elevation of 1500 m (5000 ft).
