or sometimes acute apex especially on the lower leaves ; involucral 
leaves very short-petioled, 3-cleft or 3-parted, the segments nar- 
rower and more acute than in the lower leaves ; involucels minute, 
or sometimes 14’ long; rays of umbel slender, often divaricate, 
34’-114’ long, jointed to their attachment, sharply striate, the striae 
often subserrulate-scabrous; a solitary ray or peduncle arises from 
the fork of the stem bearing a single flower cluster; fruit sessile, 
subglobose, somewhat compressed, 214-3” high to tip of calyx- 
segments, spreading across bristles 3-4”; bristles slender, at the 
base of the fruit minute but perfectly formed, longer above, the up- 
permost 1/1” long, surpassing the nearly erect calyx-segments 
which are 1%4’’-3/”’ long, linear-subulate, rigid and separated by 
distinct intervals; styles slender, diverging or slightly recurved, 
little longer than the calyx-segments; pericarp thin; commis- 
sural scar narrow, 1%” wide, usually covered witha whitish incrus- 
tation ; oil-tubes 5, arranged nearly as in Marylandica but smaller ; 
seed in cross-section suborbicular, not furrowed dorsally or but 
slightly so, the inner face medially concave or sulcate; sterile flowers 
mixed with the fertile, most numerous in the inter-rameal cluster, 
on pedicels 1’’-1 14” long, the sepals 34’’-1” long, linear-subulate or 
cuspidate, with a strong medial nerve especially noticeable on the 
inner side, at full maturity rigidly spreading; petals obovate-ob- 
long, apparently shorter than the calyx segments; roots clustered, 
very thick or sub-tuberous.

This plant, although occupying a position somewhat interme- 
diate between Sanicula Marylandwa and Sanicula Canadensis, is in 
no way involved with either of these species. From the former it 
may be distinguished by its smaller size, three-divided coriaceous 
leaves, the cauline slender-petioled, widely bifurcate stem, shorter- 
pedicelled sterile flowers, never in separate heads and having diva- 
ricate segments, smaller fruit with thinner pericarp and shorter 
styles. 
From S. Canadensis it may be known by its mostly simple stem 
terminating in two elongated branches, each bearing a long-rayed
