DC.asavariant, var. microcarpa S. Moore(also incorrectly spelt Pittosporum phyllireoides or phylliraeoides) (Cayzer etal.,2000).
Phylogenetic and morphological analyses were used by Cayzer et al.(2000) to establish Pittosporum as a monophyletic genus and reinstate species such as Pittosporum angustifolium. The first specimen of Pittosporum phillyreoides was collected in 1699 by William Dampier,then again in 1802 at Shark Bay,Western Australia (its type locality) during the Baudin expedition.Its narrow endemic range is restricted to several hundred kilometres of coastal limestone plains and adjacent islands mostly north from there
