chaetial leaves broader than the rest, sometimes regularly
4-toothed, more frequently 3-toothed ; their figure, when
expanded, orbicular and obliquely truncate, the teeth of
equal size, with reflexed margins, very like those of J . in-
cisa. Abortive pistilla surrounded by a calyx, which is
very short, and fringed with numerous laciniae half its own
length; the whole calyx shorter than the pistilla. Gemmae
consisting of large angular grains, collected into reddish
clusters at the apex of the larger segments of the leaves
which terminate the barren stem.
The specific name of this plant is singularly applicable ;
for the leaves are of nearly the same shape as if, from being
originally roundish-ovate, a semicircular portion had been
cut out from one side above the middle, and the residue
bent inwards at the sides.—W. W.
