Coprosma petriei (Coprosma petriei)
Description
The name Coprosma means "smelling like dung" and refers to the smell (methanethiol) given out by the crushed leaves of a few species.Many species are small shrubs with tiny evergreen leaves, but a few are small trees and have much larger leaves. The flowers have insignificant petals and are wind-pollinated, with long anthers and stigmas. Natural hybrids are common. The fruit is a non-poisonous juicy berry, most often bright orange (but can be dark red or even light blue), containing two small seeds. The orange fruit of the larger species were eaten by M-ori children, and are also popular with birds. It is said that coffee can be made from the seeds, Coprosma being related to the coffee plants. A notable feature (also found in other genera of Rubiaceae) is that the leaves contain hollows in the axils of the veins; in these, and on the leaf stipules, nitrogen-fixing bacteria grow. In addition the hollows, or domatia, encourage certain kinds of mites to take up residence, which feed on and reduce parasitic fungi which attack the leaf.
