Vegetative characteristics

The Coprosma species grow as creeping or upright, multi-branched shrubs , more rarely as trees . The shrub forms can develop roots at the nodes . Many species give off an unpleasant odor when injured.

The opposite or seldom alternate leaves arranged on the branches are divided into petiole and leaf blade in most species. In some species, however, the petiole is missing. The leaf blades are simple and have entire margins. The interpetiolaren stipules resemble the foliage leaves and can be grown together. They have entire or toothed leaf margins with tooth-like appendages.

Generative characteristics

The Coprosma species can be dioecious ( dioecious ), rarely monoecious ( monoecious ), separate sexes or polygamomonoeconomic . The flowers stand individually in the leaf axils or stand together in lateral, zymous inflorescences .

The mostly unisexual flowers are radial symmetry with a double flower envelope . The calyx ends in four or five, occasionally up to ten calyx teeth and is usually reduced or absent in male flowers. The petals are funnel-shaped or bell-shaped fused together and the crown ends in four or five, occasionally up to ten corolla lobes. The mostly four or five, more rarely up to ten stamens are inserted at the base of the corolla tube. The long stamens are erect or drooping. Two to four carpels are an ovary fused, each of the carpels an ovule having. The two- to four-fold lobed stylus is divided almost to its base. The elongated scar is finely haired.

The juicy stone fruits are egg-shaped to spherical. They have two to four stone cores each of which houses a single seed.

distribution

The distribution area of the Coprosma species extends from Indonesia and Borneo to Australia, New Guinea , New Zealand , Lord Howe Island , the Kermadec Islands and the Norfolk Island over French Polynesia , the Pitcairn Islands to Hawaii and the Juan Fernández Islands . New Zealand, New Guinea, Australia and Hawaii represent the main distribution areas of the genus Coprosma , as there is a great diversity of species.
