Differs from P. gunnii chiefly in being constantly dioecious not monoecious, but perhaps merely a variety as suggested by Mueller (1852). The illustrations of P. gunnii show virtually no other differences in the plants (Galbraith (1977) Wildflowers of south-east Australia, pl. 72:fig. 1; Costermans (1981) Native trees and shrubs of southeastern Australia, p. 208; Cunningham et al. (1982) Plants of western New South Wales, p. 460).
