Found on the Continent sparingly.
Obs.—Distinguished from the dioicous C. lunidcefolia, Dum.
C. catenulata (Hüben.) and C. divaricala (Sm.), in addition to
other characters, by the presence of large stipules along the whole
length of the stem.
C, fluHans (N.) is a very different plant with large lux oblong
leaves, segments obtuse, large cells. By some strange mistake
this species is figured in “ Eng. Bot.,” t. 2569, as Jiiny. Francisci.
Dr. Spruce remarks that in habit, presence of flagella, concave
leaves, small cells, the erect branches with leaves gradually becom-

clearly has an affinity with C. {Odonto.) denúdala (Mart.).
