Taxonomic notes


"Usually a small tree, sometimes with a clean trunk, more often bushy ... The trunk sometimes reaches a height of about 13 feet (4 m), with age growing at an angle or prostrate on the ground. The leaves have a blue or silvery tinge when young but become dark green with age. They are straight or the tips are curved backwards, and they are sometimes hairy in youth. The leaflets are of medium width, the middle ones just over 1/2 inch (1.3 cm) wide, with the lower margin sometimes toothed. ... Two or more cones grow together and these are up to about 1 foot (30 cm) long, the female the largest. The seeds are red and warted" (Palmer and Pitman 1972).

Distribution and Ecology

Big tree





"The specific name, meaning 'the first', refers to the fact that Dr Dyer, who described the tree, considered it the forerunner of a group of related species" (Palmer and Pitman 1972).
