Description
editPlants in the genus Wilkeia are monoecious or dioecious trees or shrubs with sometimes toothed, papery to leathery leaves with many fine oil dots. The flowers are borne in leaf axils or on the ends of branchlets in cymes or panicles, usually with 3 to 9 flowers. Male flowers are more or less spherical, with 4 to 8 tepals usually with 4 to 8 stamens. Female flowers are flattened spherical, with minute tepals with many carpels with a short stigma. The fruit is an oval, black drupe about 15–20 mm (0.59–0.79 in) long.[2][3]
Taxonomy
editThe genus Wilkiea was first formally described in 1857 by Ferdinand von Mueller in the journal Transactions of the Philosophical Institute of Victoria.[4] The first species he described (the type species), was W. calyptrocalyx,[5] now known as Wilkiea macrophylla (Tul.) A.DC..[6]
The genus appears to have an Australian or southern origin.[7]
