ovate, i-ij^ in. long by i in. wide, acuminate, serrulate; the 

 truncate base passes abruptly into a petiole of 2-4 lines. 



Peduncles generally 2 to a branch, ascending, i3^-2 in. long. 

 Each bears a single large, erect, showy flower, and is bi-brac- 

 teolate a short distance from the calyx. The sepals are narrow- 

 lanceolate, 4 lines long, drawn out at the base into a short ap- 

 pendage. The petals are 8-14 lines long, broad-oblong or 

 orbicular, on long claws, the lowest petals saccate; color pure 

 waxy white. Capsule 6 lines long ; seeds dark. 



Recorded only from the Waianae Range of Oahu, on dry, open, 

 semi-xerophytic ridges. A very handsome species, worthy of 

 horticultural experimentation. 



5, Viola Kauaiensis Gray. Described in the Botany of the 

 United States Exploring Expedition, 1854, p. 85. 



Stem either short and erect, or a creeping or trailing rhizome 

 which may be more or less subterranean. Rhizome 2-3 lines in 

 diam., scaly near the apex with obtuse stipules, and bearing (be- 

 sides the remnants of older ones) i or 2 slender scapes 4-8 in. 

 long. These scapes have i internode and a single leaf and flower, 

 or with 2 internodes and a second leaf and flower. Petioles 

 slender, 2-6 in. long. Blade broadly ovate, orbicular, or reni- 

 form, with a cuneate base, less than i in. diam., rather thick with 

 prominent subflabellate veins; margin crenate, surface glabra te. 

 Stipules deltoid, 2-3 lines long, with a few short teeth. 



Petaliferous flowers on peduncles of 2-4}/^ in., which bear a 

 pair of short subulate bracts in the upper portion. Sepals 2>}/2 

 lines long, narrow-lanceolate, the base produced into a short 

 appendage. Petals twice as long, pale blue, not bearded, oblong- 

 spathulate, the lowest one slightly saccate. Anthers free, half 

 as long as the sepals, attached to the anterior face of a broad con- 

 nective which fringes them and extends above in the shape of a 

 hood. The 2 lowest anthers have a short dorsal keel near the 

 base. Style curved, clavate above, with anterior stigma. The 

 smaller flowers have petals not exceeding the calyx; stamens with 

 distinct filaments nearly equalling the petals; style thicker and 

 hooked. Capsule acute, 5-6 lines long, with 8-10 seeds in each 

 placenta. 



Recorded only from the swamps on the upper slopes and sum- 

 mit of Wai-ale-ale, Kauai, 4,000 — 5,250 feet. It grows in the 

 shade of the stunted lehua trees {Metrosideros polymorpha) that 

 are characteristic of these swanii)s, and also epiphytically on the
