This new species, which is a tree 20 feet or more high, with a trunk of several 
inches in diameter was discovered by the writer in the forests of Naalehu, Kau, 
Hawaii, in the tropical rain forest situated on the southern slopes of Mauna 
Loa at an elevation of 3000 feet. The bark of this tree is fawn-colored and 
eorky, the sap-wood yellow like that of the Noni (Morinda citrifolia), the heart- 
wood is blackish; when cut into an exceedingly large amount of sap squirts 
out in all directions, having a very peculiar oily odor. The wood is quite 
close grained and comparatively hard. It was collected in flower buds and fruit 
on January 9, 1912. The type is no. 10005 in the College of Hawaii Herbarium.

This species, often a shrub, was however observed only as a small tree 15 to 18 
feet in height. It oceurs only in the rain forests and is quite common in the 
mountains of Kohala, Hawaii, where the writer collected it, as well as in the 
valleys of Waipio, Puakalehua, Waimanu, ete. According to Hillebrand it oe- 
curs on all the islands of the group, but the typical C. pubens was collected only 
on Hawaii by the writer. It is distinguished from the other species of 
Coprosma in the numerous flowers, which are glomerate at the end of a short 
pedunele, and the narrow ellipsoidal fruit.
