Nani(a) glabrifolia n. sp. 



A large tree, thirty to forty feet high, with a trunk diameter 

 of two to five feet; main branches stout and spreading, young 

 branches crowded, angled, with short internodes; leaves nu- 

 merous, broadly ovate, usually cordate at base, on very short 

 petioles, glabrous; the short, stout, peduncles and pedi- 

 cels as well as the calyx, shortly pubescent, but not wooly; 

 fruit three- fourths free; flowers bright red. 



The type is No. 2821, which is abundant at an elevation of 

 4000 feet, on the plateau above Waimea, Kauai. Specimens 

 with the fruit of the previous season, were collected from a 

 tree which had been blown down during a wind storm. Early 

 in October, when I left this place, the trees were just coming 

 into bloom. 



No. 2053, collected en Tantalus, back of Honolulu, may per- 

 haps be referred to N. glabrifolia. The specimens were from a 

 small tree. The leaves are on longer petioles, and the flowers 

 are yellowish. 



Nani(a) tremuloides n. sp. (Plate l VI.) 



A small tree, ten to twelve feet high, with slender trunk and 

 smooth, grayish bark, glabrous throughout, even the inflor- 

 escence; branches slender, loosely spreading; leaves narrowly 

 lanceolate, pointed at both ends, coriaceous, shining, bright 

 green above, paler beneath, on flat, slightly winged petioles a 

 fourth of an inch in length, not prominently veined, but midrib 

 conspicuous; cyme branches divaricate; peduncles three flow- 

 ered, slender, of varying length, but always under a half inch; 

 pedicels usually half the length of the peduncles, calyx cam - 

 panulate, a fourth of an inch in length, green, the lobes equal- 

 ing the tube, ovate, blunt, margins scarious; petals bright red, 

 almost orbicular, nearly twice the length of the calyx lobes, 

 the margins slightly eroded; stamens bright red, barely an inch 

 in length; styles slightly longer than the stamens, the end 

 curved; fruit half free. 



The type is No. 2895. A beautiful and well marked species, 

 with constant characters, at least on the island of .Oahu. It seems 

 to be the var. • zeta of Gray, and is var. theta of Hillebrand, 

 who says it is confined to Oahu and Kauai. The natives, who 

 in former times were very good botanists in their way, recog- 

 nized this form as distinct from the others, and called it 

 "Lehua ahihi." Specimens were collected at the NuuanuPali, 

 and at various places on the slopes of Konahuanui, Oahu. It
