Rubiaceae. 



chartaceous, glabrous on both sides, 8 to 12 cm long, 3 to 4 cm wide; on petioles of 3 to 4 

 cm; stipules broad sheathing, thin, 8 mm high, slightly broad, ciliate at the upper border; 

 flowers 2 to 3, sessile at the end of a short axillary peduncle of 2 to 5 mm; bracts 2.5 mm; 

 (flower buds only known) calyx urceolate, very short dentate; corolla about 4 mm; drupes 

 oblong-ellipsoidal bright red, usually single, 12 mm long, crowned by the calycine teeth; 

 seeds whitish, rounded at the apex, acute at the base, oblong. 



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 

 corky, 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.

Leaves lanceolate or obovate-oblong, 5 to 12.5 cm long, 2.5 to 3.5 cm wide, on petioles 

 of 10 to 20 mm, acuminate, narrowing at the base, chartaceous glabrous, or pubescent at 

 higher elevations, dark when dry; stipules 4 to 8 mm, loosely sheathing on half their length, 

 the free portions' triangular, strigose-pubescent; flowers numerous, glomerate at the apex of 

 short peduncles; male flowers: calyx 2 mm, corolla 6 to 8 nim long, 6 to 7 lobed; female 

 flowers: calyx 2 to 4 mm, cylindrical, the very short limb dentate; corolla 4 mm; styles 

 18 to 16 mm; drupes reddish, ovoid or ellipsoidal, 8 to 12 mm long, naked at the top, the 

 pointed apex projecting beyond the calycine scar. 



This species, often a shrub, was however observed only as a small tree 15 to 18 

 feet in height. It occurs only in the rain forests and is quite common in the 

 mountains of Kohala, Hawaii, where the writer collected it, as Avell as in the 

 valleys of Waipio, Puakalehua, Waimanu, etc. According to Hillebrand it oc- 

 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 

 peduncle, and the narrow ellipsoidal fruit.
