Fossil pollen of acacia type from New Zealand

Abstract

Numerous specimens of a pollen grain polyad similar to those of the present day Acacia have been found in a Castlecliffian (Middle Pleistocene) sample from the North Island of New Zealand. Their abundance suggests that the genus Acacia was represented in the Quaternary flora of New Zealand. It may have become extinct during the “last glaciation”. Fossil localities where Acacia has been recorded are listed.
