Coprosma robusta, commonly known as karamū, is a flowering plant in the family Rubiaceae that is endemic to New Zealand. It can survive in many climates, but is most commonly found in coastal areas, lowland forests, or shrublands. Karamū can grow to be around 6 meters (20 feet) tall, and grow leaves up to 12 centimeters (4.7 inches) long. Karamū is used for a variety of purposes in human culture. The fruit that karamū produces can be eaten, and the shoots of karamū are sometimes used for medical purposes.

Identification

Species description

Karamū is a large bushy shrub that grows up to 6 meters (20 feet) tall. Branches are stout with no hair. Domatia (small holes on the back of the leaf at the intersection of veins) and stipules are significant characteristic features of Coprosmas. Karamū stipules are black, hairless and obtuse with slightly serrated margin that are united at the base 

Leaves

The glossy leaves of karamū range from 5 to 12 centimeters (2.0 to 4.7 inches) long, with elliptic-oblong shape and acute or obtuse leaf apex and with obvious veins. Leaves are dark green on the blade and light green on the back, are thick, and the midrib is not raised on the upper surface.

Flower

Flowers are small and white, axillary, dense, have four lobes and have a different appearance in male and females. Male flowers are dense, glomerules with a campanulate shaped corolla and have four stamens; female flowers are compound with a tubular shaped corolla. Stigmas are obvious. The best flowering period is between August and September.

Fruit

Fruit are often dark orange-red to red, oblong to narrow ovate drups. The best fruiting period is between April and May.
