Abstract
Alseuosmia quercifolia A.Cunn., previously treated as a hybrid (A. ×quercifolia) or as an entity informally known as A. sp. “Hakarimata”, is reinstated as a distinct species. This species occurs most commonly in lowland native forests of the Waikato region (from 38OS), but also occurs in sparse populations as far north as North Cape. Although lamina morphology is somewhat variable, A. quercifolia has a set of morphological characters unique to the species and not intermediate between formerly putative parents A. banksii and A. macrophylla. It is distinguished from A. banksii by its slightly larger flower, larger leaf, different petiole and lamina colour, distinctive pale venation of seedling leaves, and later flowering season; from A. macrophylla by its smaller flower, and by different lamina, petiole, and stem colour; and from A. pusilla and A. turneri by its different petiole and lamina colour.
