34 New Hawaiian Plants. <i 
described no Hibiscus with the characters of Hibiscadelphus, though 
Rev. J. M. Lydate informed me, that he remembered collecting this 
species at Kawaihae, and calling Hillebrand’s attention to its pecul- 
iarities. It is difficult to understand why Hillebrand should send 
specimens to Mann without retaining duplicates, but Mr. J. F. Rock 
informs me that he saw no specimens of Hibiscadelphus in the 
Hillebrand collection at Berlin. As the native vegetation at Ka- 
waihae has practically disappeared, the species is probably. extinct. 
Viola kauaiensis Gray, far. wahiawaensis, var. nov. 
PLATE IV. 
This well marked variety differs from the species in its leaves which 
are cuneate at the base, never truncate or reniform. As in the species the 
petioles vary greatly in length, and the fragrant flowers vary in size. All 
the plants observed at the Wahiawa bog belong to the variety, those at the 
type locality, mountains above Waimea, Alakai swamp, and Lehua makanoe, 
to the species. 
Type in the B. P. B. M. Herbarium, collected at the Wahiawa swamp, 
Kauai, IT. H., August, 1909, by C. N. Forbes, No. 166, K. ‘There are two 
unnumbered specimens in the B. P. B. M. Herbarium, collected at the 
Wahiawa swamp by Rev. J. M. Lydgate. 
Cyrtandra olona, sp. nov. 
PLATE V. 
Stem 6 dm. high, unbranched, glabrous in all parts. Leaves opposite, 
broadly ovate in outline, obtusely rounded at the apex, truncate at the base, 
a few slightly uneven-sided, crenate except at the base, glabrous, very dark 
green above, paler below, nerves prominent, 15.4-16 cm. long, 12-12.5 cm. 
wide, petioles 6-11.5 cm. long. Flowers (several?) on a common peduncle of 
7 mm.; the pedicels of the same length, bracts not seen. Calyx cup-shaped, 
shortly 5-cleft with deltoid, acute lobes, glabrous, 8 mm. high. Corolla small, 
white, slightly curved, 1.1 em. high. Ovary glabrous. Fruit not seen. 
Type in the B. P. B. M. Herbarium, collected at the Wahiawa moun- 
tains, Kauai, T. H., August, 1909, by C. N. Forbes, No. 213, K. 
The mature, bluish-green, and the coarsely veined juvenile 
leaves are rather suggestive of the Olona, Touchardia latifolia. ‘The 
species is distinct from any Cyrtandra known to me, but may prove 
to be distantly related to C. cyaneoides Rock. Only a single speci- 
men of each of these Cyrtandras is recorded.
