i86 THE CROWFOOT FAMILY. 



flowers have rounded petals and shorter, pointed sepals. The leaves are 

 pinnately divided into from three to five broad segments, oblong or ovate 

 and which also are sharply lobed, or cleft. Even when in fruit the plant is 

 densely villous with yellowish, silky hairs. 



R. Peiinsylvdnicus, bristly buttercup, does not begin to bloom until June 

 when through open meadows or in wet places it throws out small flowers, the 

 rounded petals of which are as long as, or a little shorter than, the pointed, 

 reflexed sepals. It is an erect, somewhat slender plant with fresh, bright 

 green leaves, thrice-divided, cleft and lobed so as to appear light and fern- 

 like. On nearly all its parts it is covered with a thick, bristly pubescence.

Masses of feathery, fleecy, little flowers proclaim through damp woods 

 the presence of the mountain meadow rue. But its most constant charm, 

 perhaps, lies in its fern-like spray of graceful apple-green foliage tinted 

 underneath as it is with misty blue.

Often we notice about this meadow rue that the flowers of separate plants 

 do not look alike. In one place will.be a clump of those with white, rather 

 showy blossoms and not far distant we see them of a purplish, misty tint. 

 This is because the staminate and pistillate flowers are borne on different 

 individuals, — in fact in two households. Then as they usually tower above
