Coprosma macrocarpa - large-fruited Coprosma

Coffee family: Rubiaceae

Coprosma macrocarpa is a bush with stout opposite branches with broadly elliptic and leathery leaves. Stipules (appendages at the base of leaf stalks) are fused into a sheath and have a prominent gland at their tip when young but soon dry and shrivel and are shed. Pits (domatia) are found on the underside of leaves where lateral veins join the midrib. Flowers are borne clusters at the ends of branches (peduncles).
An endemic species found on the Three Kings Islands but naturalised in Auckland and around Wellington.
