A contribution to the tertiary occurrence of the genus Dacrydium in the Australian region

Abstract

Foliage shoots and seeds of a new Tertiary species, Dacydium rhomboideum, are described; the affinity of D. rhomboideum is discussed.

A new sporomorph, Dacrydiumites florinii, is proposed for fossil pollen grains, similar to those of certain species of Dacrydium, isolated from Tertiary deposits in Australia, Tasmania, and New Guinea.

Descriptions of the pollen grains of the living species Dacrydium araucurioides and Dacrydium balansae are included.
