Tertiary Alangium (alangiaceae) in eastern Australia: Evidence from pollen

Alangium has large, distinctive pollen grains which may allow identification to species and species groups. In Australia, there is one species, A. villosum (Blume) Wangerin, with two subspecies restricted to rainforests of the east coast of the continent. The pollen of both subspecies is the distinctive A. villosum type of Reitsma (1970). Two Tertiary pollen types of Alangium are formally described as the new form species Clavastephanocolporites meleosus and C. blysus; these are morphologically similar to the A. villosum type and the Alangium salviifolium type of Reitsma (1970), respectively. These records complement the numerous Tertiary occurrences in the Indo-Malesian region and elsewhere.
