 A large tree, with heavy branches, and thick, leathery, ovate 

 leaves. Flowering specimens were collected on the ridge west 

 of the Hanapepe river, Kauai, at an elevation of 3000 feet. It 

 is found only on the islands of Oahu and Kauai.

 Collected at the type locality, "mountains behind the town 

 of Honolulu." One form (2240), which was distributed as 

 Eurya sessilifolia, n. sp., is apparently only a sessile leaved 

 form, and is mentioned by Gray in the original description. It 

 grew near the summit of Konahuanui, and has larger, more 

 crowded, sessile leaves, which are clasping at the base. No. 

 2311, the normal form with smaller, petioled leaves, was col- 

 lected on the same mountain, but at much lower elevations — 

 about 2000 feet.
