Dacrydium is a genus of conifers belonging to the podocarp family Podocarpaceae. Sixteen species of evergreen dioecious trees and shrubs are presently recognized. The genus was first described by Solander in 1786, and formerly included many more species, which were divided into sections A, B, and C by Florin in 1931. The revisions of de Laubenfels and Quinn (see references), reclassified the former section A as the new genus Falcatifolium, divided Section C into new genera Lepidothamnus, Lagarostrobos and Halocarpus, and retained Section B as genus Dacrydium.
