Hawaiian Islands (Gaudichaud). Oahu (Mann and Brigham); 
Nuuanu (Cooke). The writer has had the privilege of examining 
the type-specimens in the Montagne herbarium. 
Compared with C. lunulefolia Dumort. (= C. multiflora), of 
Europe, North America and Asia, there are the following differences: 
the Hawaiian species is monoicous while the other is dioicous, the 
leaves of C. Sandvicensis are less orbicular and much more deeply 
bifid, the perianth is 1 cell thick throughout, and its mouth is 
laciniate instead of being dentate. 
C. Sandvicensis is very close to C. connivens in its vegetative 
characters, but its sexual characters differ somewhat. In the former 
the lobes of the bracts are much shorter and are neither dentate nor 
denticulate, in the latter species the bracteole is much more connate, 
the mouth of the perianth is more deeply laciniate in the Hawaiian 
species. 
C. forficata Spruce, of tropical America, agrees most closely with 
our species, but is dioicous ; in C. Sandvicensis the leaves are more 
deeply bifid, with a more or less .acute sinus; in (0. forficata the 
lobes are narrower and are separated by a lunate sinus. Spruce in 
his comparison between C. Sandvicensis and C. forficata uses the 
words “fere constanter strictis (nec conniventibus) ” as a character- 
istic of C. Sandvicensis. The writer has found a great variation 
in the position of the apices of the lobes; on the same stem leaves 
can be found with the lobes overlapping, connivent, parallel or 
spreading.
