other and the lobe is more sharply pointed. In most cases the 
lobe shows no teeth whatever, but occasionally one or more angular 
teeth can be distinguished. The condition described for the lobule 
may be considered typical, but the number of teeth present in 
the apical region varies considerably and they are not always sharp. 
In rare cases the apex of the lobule is merely truncate or retuse 
with blunt angles. When severa! teeth are present the apical 
tooth usually projects beyond the others, and the hyaline papilla 
may be discerned at the bottom of the sinus on its proximal side. 
The bracteoles vary in much the same way as the lobes, the divi- 
sions being usually entire but sometimes variously dentate. On 
account of the frequency with which the apices of the divisions 
are inflexed, it is often difficult to observe the peculiarities of the 
bracteole clearly without dissection. 
Among the species allied to C. integrifolia it will be sufficient to 
mention C. cubensis. In this plant the lobules, underleaves, bracts, 
and bracteoles are much the same as in the new species except that 
the lobes of the bracts and the divisions of the bracteoles tend to be 
more regularly toothed. The leaf cells, also, are very similar and 
there are no differences in the ocelli; the cells, however, sometimes 
show distinct trigones and intermediate thickenings. The autoi- 
cous inflorescence of C. cubensis and the dentate leaf lobes will 
at once serve to distinguish it. The teeth are situated in the 
apical region of the lobes and usually vary from two to five; they 
tend to be more conspicuous on branch leaves and are occasionally 
indistinct on robust stem leaves.

Pale green, growing among other hepatics or forming loose 
Waa mats: stems 0.12 mm. in diameter, loosely and irregularly 
pinnate, the branches widely spreading, usually with smaller 
leaves than the stem, at least in basal portions: leaves loosely to
