Radix subrepens, fibrosa. Caulis gracilis, glaber, spithameeus 
et ultra, nunc pedalis, decumbens, ramosus; ramis elon- 
gatis tenuibus simplicibus foliosis, ex axillis petiolorum 
progredientibus. Folia sparsa, magis minusve petiolata 
etiam ad extremitates ramorum: inferiora multo majora 
(vix ulla omnino radicalia) longe petiolata, orbiculata seu 
ovali-orbiculata; petiolo sursum dilatato, non raro hinc 
lobulo solitario aucto seu unifoliolato; hinc folium sub- 
compositum: superiora sensim minora, late ovalia, omnia 
obtuse sinuato-dentata breve petiolata. Flores in corym- 
bum seu racemum dispositi, remoti, minores quam in

Dr. Darlington has observed a pair of lobes on the petioles 
of the larger leaves, hence showing a great disposition to be- 
Come pinnated, as is the case with the greater number of spe- 
cies of the genus. The same author farther remarks; ‘the 
C. rotundifolia continues to extend its slender branches, fresh 
and green, nearly throughout the summer: they usually lie 
_ Prostrate on the mud, and often strike root after the manner of 
creeping or radicating stems, a circumstance never observed
