definition Distribution: Asteraceae is the family of flowering plants, with an estimated 1600+ genera and 24,000 species (plus many more apomictic microspecies) found worldwide (except Antarctica), and growing in most habitats. In Australia about 300 genera and 1417 species, the native taxa mainly in subfamilies Asteroideae (Tribes Astereae and Gnaphalieae). Asteraceae is the second most speciose family in Australia, exceeded only by the Myrtaceae (c. 89 genera and c. 1858 species) and rivalled only by the pea-flowered legumes (c. 140/1402) and Poaceae (c. 230/1300)

Description: This family are a group of annual or perennial herbs, subshrubs, shrubs or rarely small trees or lianes, usually terrestrial, rarely facultatively aquatic.

Pollen Morphology: The shape of the pollen in this family is highly variable and can be separated into two grain types. Type 1 grains are circular to clover shaped and often appear as a spikey ball. These pollen grains also have three pores and furrows (tricolporate), however they may be difficult to see. Type 2 grains have flat panels in a snow-flake like shape and have window-like apertures. The surface of these pollens are also spikey. The size of the pollen in both groups are variable with most taxa being 20-25um in diameter but some are seen to be smaller (15um).
