fruit and leaves, the latter with finely-cut marginal pattern, the 
branching widely dichotomous and confined mainly to the upper 
part of the stem; the opposite form is coarser and stouter, with 
ascending or even-suberect, often simpler, branches and larger 
fruit; the leaves are much larger with coarser serration, and more 
trifoliate tendency, those of the upper stem sometimes perfectly 
trifoliate. An extreme example of this form in the Columbia Col- 
lege Herbarium, labelled «« Massachusetts ” in Dr. Torrey’s hand- 
writing, is the only specimen seen in which the character of 
short styles does not hold strictly true; in this specimen, which 
is in the flowering stage, the styles are longer than the sepals, and 
somewhat spreading, though not recurved. It is to be said, how- 
ever, that this particular plant is pretty certainly abnormal; the 
branching is unusually coarse, and the rays and pedicels some- 
what thickened, apparently indicating a tendency to fasciation. 
SANICULA TRIFOLIATA n. sp. 
About two feet high; branches several, alternate, ascending, 
or the lower often longer and suberect, simple, terminating either 
in the flowering umbel or in two frequently widely-spread- 
ing umbel-bearing rays, with a shorter simple ray between ; rays 
of flowering umbels three to five, about an inch long; involucres 
and involucels of small serrate leafy bracts. Cauline leaves petioled, 
large, five to seven inches broad, conspicuously trifoliate, the 
broad leaflets petiolulate, ovate, elliptic-ovate or rhombic, coarsely 
doubly serrate with rather open, almost spinescently-mucronate 
teeth, or even incised-lobed, acute, the lateral leaflets mostly not 
at all cleft, except sometimes in the lower leaves; basal stem- 
leaves long-petioled, smaller than the main cauline leaves, the 
leaflets even slightly united at base, often obtuse, the lateral pair 
Narrowly cleft on the lower side, but not sufficiently so to destroy 
the trifoliate character of the leaf. Sterile flowers few, 14” or less 
long, on slender pedicels about 2’ long ; sepals lanceolate, acumi- 
nate-cuspidate with slightly incurved points. Fruits sessile, three 
to five together, somewhat reflexed at maturity, ellipsoid or 
globose-oblong, large, becoming 3%” high to tip of the erect 
Sepals, the greatest spread of the bristles under 3’’; prickles 
Stout, swollen below, not crowded, small and reflexed at the 
base of the carpel, above becoming 114” long, and spread- 
ing or ascending; sepals on mature fruit 1” long, united at 
base, appressed, echinate with sharp, slightly incurved points, 
raised on a slight prolongation at the apex of the fruit, and 
forming a conspicuous beak-like projection quite distinct from the
