Its leaves are quite thick and fleshy, and are usually glaucous on both 
sides. 
Sanicula serpentina, n. sp.—Low spreading biennial or perennial 
herb, from slender rootstocks, 2 high or less, wholly glabrous and 
frequently somewhat glaucous, a rich brown color when cured: stems 
chiefly branched from the base, the central one erect, the marginal 
ones ascending: leaves mostly from the base, subtending the branches, 
the radical ones upon membranously flattened 3-nerved petioles 2°™ 
long; blade proper 2°™ long or longer, ovate in outline, 3°™ across 
the base, pinnately divided into laciniate lobes which are again 
divided into slender acuminate usually somewhat recurved and 
sharply pointed segments: inflorescence branched from near the 
base, long-pedunculate; involucre of sessile leaf-like bracts; heads 
3 to 5, the peduncles of the lateral heads usually much shorter at 
least when in flower, densely flowered, about 4™™ in diameter; 
involucels of entire lanceolate bracts slightly shorter than the yellow 
flowers; marginal flowers sterile, pedicelled, the fewer inner ones 
sessile and fertile: calyx 5-toothed: petals 1-nerved, quite broad 
across the middle, the setaceously acuminate apex strongly inflexed 
and emarginate on its bend: stamens incurved near the apex; 
anthers broadly elliptic, o.5™™ long: ovary with uncinate prickles; 
styles 2, slender, recurved, each persistent from the inner face of the 
stylopodium: fruit not observed. 
ype specimen no. 4498, collected in April 1903 near Portola, San Mateo 
County, California. 
This form is nearest related to S. laciniata H. and A., but the latter is a much 
more rigid herb, with coarser, broader, spinosely toothed leaf divisions; and 
with the bracts of the involucels often 3-parted or at least 3-nerved from near 
the middle. It was discovered on serpentine rocks near Searsville Lake, of the 
chaparral formation. 
Trifolium bicephalum, n. sp.—More or less tufted, from an 
annual root: stems slender, 8 to 18°™ long, decumbent or the outer 
ones prostrate, rather numerous from the base, rarely branched, 
sparsely pubescent: leaves both radical and cauline, the basal ones 
somewhat smaller and more numerous, with slender flexuous pubes- 
cent petioles 2°™ in length; stipules adnate, 6™™ long, membranous, 
strongly nerved, subglabrous or finely ciliate along the edges, termi- 
nated by two setae 2™™ long; leaflets 7™™ long, 4™™ wide, soft pubes-
