Coprosma

Coprosma is a genus of about 90 species that are found in (45 spp), Hawaii (c. 20 spp) and in Borneo, Java, New Guinea, islands of the Pacific Ocean to Australia. 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. 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 the Rubiaceae) is that the leaves contain hollows in the axils of the veins; in these, and on the leaf stipules, nitrogen-fixing bacteria grow.
