PoTENTILLA PENNSYLVANICA ARACHNOIDEA Lehm. Nov. Stirp. Pug. 
G40. TEST. 
Plant in every part smaller; segments short; stem arachnoid- 
pubescent. Colorado, Utah and New Mexico. 
- PorENTILLA PENNSYLVANICA GLABRATA Wats. Proc. Am. Acad. ie 
§$4. 1672. 
Low, stem puberulent or glabrate; leaves nearly glabrate and 
- the sepals more distinctly veined. Perhaps distinct. Nevada, 
Montana and Assiniboia, in the higher mountains. 
POTENTILLA LITORALIS. 
Stem decumbent or ascending, 2-4 dm. long, simple, slightly 
appressed silky strigose. Lower stipules lanceolate, scarious and 
brown, the upper ovate, green, more or less toothed. Leaves pin- 
nate, of two. approximate pairs of leaflets, the lower pair the smaller, 
or subdigitately 5-toliolate, grayish tomentose and veiny beneath, 
nearly smooth above. Leaflets obovate, divided to near the 
mid-rib into linear oblong obtuse divisions. Calyx strigose and 
slightly tomentose, in fruit about 8 mm. in diameter. Bractlets 
lanceolate-oblong, nearly equalling the ovate triangular sepals. 
Petals obovate, cuneate, truncate or slightly emarginate, about 
equalling the calyx ; stamens 20-25 ; style short,terminal, thickened | 
and glandular at the base;:achenes smooth. 
A near relative of P. Pennsylvanica, but differs in the ascend- 
ing or spreading stem, the sparser pubescence, the leaves, which 
have fewer and approximate leaflets, often almost digitate, and the 
sepals which are more distinctly ribbed. P. /toralis is principally 
a beach plant, or at least growing near the coast, while P. Penm- 
sylvama is an inland plain or mountain plant. The following spe~ 
cimens belong to P. “itoralis : 
New Hampshire: Oakes & Robbins (Isle of Shoals), W. M. 
Canby. Maine: Wm. Boott (Cape Elizabeth), M. L. Fernald. 
Newfoundland : Waghorne, no. 8, 1895. Quebec: J. A. Allen, 1881 
(Shores of St. Lawrence). Ladrador: J. A. Allen, 1882. 
POTENTILLA MULTIFIDA L. Sp. Pl. 496. 1753. 
This is a species which somewhat resembles P. Penmsylvanica 
bipinnatifida, but the plant is spreading or ascending, the leaves of a 
only 2—3 pairs, their segments nearly filiform with revolute margins, __
