Byronia sandwicensis Endl. Ann. Mus. Wien. 1 : 184. 1836. 



On the ridge west of the Hanapepe river, Kauai, at an eleva- 

 tion of 3000 feet, specimens were collected which seem to be 

 identical with those of the U. S. Exploring Expedition, plate 

 26. They were obtained from a small much branched tree, 

 which differs from B. anomala in being more branched, the 

 leaves smaller and more scattered, and the inflorescence is very 

 different. Instead of being almost terminal and ascending, it 

 is axillary, the peduncles and pedicels more widely spreading, 

 and not so stout, The flowers are amaller, and the fruit is 

 narrower and longer.

Byronia sandwicensis Endl. var. 



This form is hardly separable from the above, yet is constant 

 enough in localities where it occurs. It differs in being less 

 branched, has more crowded leaves nearly elliptical in out- 

 line, instead of obovate, and a more copious inflorescence. In 

 the bog at the head of the Wahiawa river, Kauai, it is found as 

 a low shrub, with ascending branches, while above Waimea, on 

 the plateau, it is a larger bush, with more spreading branches.

Collected at the type locality, " on mountains behind Hono- 

 lulu, Oahu." It is common on the lower slopes of Konahuanui, 

 and also on the island of Kauai. On the latter island it ranges 

 as high as 4000 feet, but is also found in the lower woods along 

 the Hanapepe river. A small tree, with light green, red- 

 veined shining leaves.
