Silene nov. sp., (No. 1). Shrubby, green-flowered. On Mauna Roa, at the elevation of 

 6500 feet. In the pastoral district on Mauna Kea, to the elevation of 11,200 feet; 

 the flowers large, green, the petals notched or emarginate. 



nov. sp., (No. 2). Shrubby at base; leaves larger than in Mauna Roa sp., lan- 

 ceolate; a terminal naked corymb of white flowers. On the tabular summit of Tauai. 



Nov. gen. Silenoid, (No. 3). A shrub with linear, almost Ericoid or heath-like leaves. 

 In the environs of the Great Crater. On Mauna Haleakala, at the elevation of 5500 

 feet, but rare. 



Nov. gen. Geranioid, (No. 1). A shrub, two to three feet high, with something of the 

 habit of Aronia; stems clustered, a third of an inch in diameter, and leafy only at the 

 summit; under surface of the leaves silvery; flowers white. On Mauna Roa, above 

 the elevation of 6100 feet, not abundant. In ripening, the elastic base of the stigmas 

 curves upward bearing the attached carpel ; agreeing in this respect with Geranium, 

 and according to jMr. Brackenridge, " dittering from Pelargonium." 



; seeming distinct ; the upper surface of the leaves silvery. In the pastoral dis- 

 trict on Mauna Kea, to the elevation of 11,000 feet. And on Mauna Haleakala, from 

 the elevation of 5500 to 9500 feet. 



; like the first sp., but perhaps distinct; the leaves very small. On the tabular 



summit of Tauai. 



nov. sp., (No. 2). A vshrub, three to six feet high ; leaves ovate, serrate, entire

 in this respect of Pelargonium. On Mauna Haleakala, from the elevation of 5500 to 

 6700 feet ; usually a shrub, three to six feet high, but on the Northern flank becoming 

 a tree fifteen feet high, with the trunk eight inches in diameter; (a section of a pri- 

 mary branch, given ofl' about six feet from the ground, was brought away by Mr. Brack- 

 enridge). The same species was found by Mr. Rich on Hawaii, probably on the Western 

 side of Mauna Roa. 



Dodonsea (bis No. 1 lower down). On Mauna Roa, to the elevation of 6500 feet, the 

 leaves lanceolate and the fruit large. On Mauna Haleakala, to the elevation of 8000

Edwardsia (No. 1) ; the " mamani" tree. Leaves pubescent on both sides. In the 

 environs of the Great crater, somewhat rare; but commencing on the Leeward side at 

 the elevation of 1000 feet, and extending to 6500 on Mauna Roa. In the pastoral 

 district on Mauna Kea, becoming a tree, twenty feet high with the trunk eight to 

 twelve inches in diameter; growing in an isolated or scattered manner as fur as the 

 elevation of 9500 feet. On Mauna Haleakala, occurring only as a shrub, and com-
