dissection of flower, f. 7; stamens, f. 8; pistil, f. 9; fruiting hypanthium and calyx, f. 70. 
Stems many from the caudex, low, at last spreading, generally less than 2 dm. high, appressed 
silky-strigose. Stipules large, lanceolate, acuminate, more or less searious and brown. Leaves pin- 
nate, of 2-8 pairs of leaflets, grayish-tomentose beneath, smooth above ; leaflets pectinately divided to 
very near the midrib into linear acute revolute divisions. Hypanthium silky-strigose, in fruit 5-7 
min. in diameter; braclets oblong-lanceolate, acute, a little shorter than the oyvate-lanceolate acute 
sepals. Petals cuneate, emarginate, a little exceeding the sepals. 
This is a species which somewhat resembles P. bipinnatifida, but the plant is spreading or ascend- 
ing, the leaflets only 5 to 7, their segments nearly filiform with revolute margins, the stipules 
long-acuminate, scarious and brown, the sepals narrower and the style not thickened and glandular at 
the base. It is not rare in northern and alpine Europe and Asia, but J have seen only the following 
specimens from America.
