  Doust, Andrew, N.L.
In most genera of Winteraceae a continuity of initiation from sepals through petals, stamens, and carpels results in relatively few floral arrangements, these being variations on decussate and whorled patterns.
In all taxa there is within-pattern variation in divergence angle and plastochrone ratio correlated with the eccentricity of the floral meristem.
Differences in floral form define the genera of the Winteraceae and these differences are controlled by the timing and duration of primordial initiation, the position of initiation of the primordia, the shape of the floral meristem, and the relationship between size of meristem and size of primordium.

  Winteraceae - Wikipedia, the free encyclopedia
The Winteraceae are a mostly southern-hemisphere family associated with the Antarctic flora, found in tropical to temperate climate regions of Malesia, Oceania, eastern Australia, New Zealand, Madagascar and the Neotropic.
The Winteraceae are characteristic of the Antarctic flora, which has its origins in the southern portion of the ancient supercontinent of Gondwana, and is generally found in humid temperate and subtropical regions of the southern hemisphere, and at higher elevations in the humid tropics.
Winter's Bark (Drimys winteri), a slender tree native to the Magellanic and Valdivian temperate rain forests of Chile and Argentina, is grown as a garden plant for its handsome and fragrant mahogany-red bark and bright-green leaves, and its clusters of creamy white jasmine-scented flowers.

Drimys is a genus of woody evergreen flowering plants, part of family Winteraceae.
The Winteraceae are primitive dicots, associated with the humid temperate Antarctic flora of the southern hemisphere, which evolved millions of years ago on the ancient supercontinent of Gondwana.
Members of the family generally have aromatic bark and leaves, and some are used to extract essential oils.

In St. Louis in June, while celebrating his 87th birthday and the publication of his latest synthesis on the classification of flowering plants, Dr. Takhtajan was presented with a specimen of Takhtajania for the Komarov Botanical Institute in St. Petersburg.
The family Winteraceae consists of 9 genera and 100 species distributed in the montane subtropics and tropics of Mexico, Central and South America, most diverse in southeastern Australasia, and absent from Africa, except Madagascar.
Along with the Magnoliaceae, the Winteraceae is considered by most modern classifications to be one of the oldest known flowering plant families.

It is a member of the family Winteraceae, one of the group of plants associated with the ancient Gondwanan supercontinent, and members of the family are found on New Caledonia, New Zealand, the Solomon Islands, parts of Indonesia, and from southern Mexico to Cape Horn and the Juan Fernandez group.
Many members of the family have been used in traditional medicine in the regions in which they are found.
The leaves and berries of the plant are now used in Australia to lend a 'wild, natural and spicy' taste to foods of the native food genre, such as emu hamburgers, flavoured breads, pastas and pates, mustards and cheeses and are finding their way into the kitchens of many of the more innovative restaurants.

Cladistic analysis of these fossils plus modern Winteraceae and Illiciales, which have been associated with each other, implies that Afropollis and Schrankipollis represent an extinct sister group of Walkeripollis, Winteraceae, and Illiciales, derived from a common ancestor before origin of the tetrad condition.
These results imply that extinct relatives of Winteraceae and Illiciales were an important component of Early Cretaceous tropical floras and extended into Laurasia, and that the present austral temperate distribution of Winteraceae was attained later.

In combination with phylogenetic analyses of morphological and molecular data from modern plants, fossils allow improved reconstruction of the history of the Winteraceae.
Phylogenetic analyses link the Winteraceae with the Canellaceae, nested among Magnoliales, Laurales, and Piperales, implying that their lack of vessels is derived rather than primitive.
Late Cretaceous paleogeography suggests that the crown-group could have dispersed to Australasia via either South America and Antarctica or Madagascar (where the family is represented by the basal genus Takhtajania) and India.
