ROSE FAMILY. Rosaceae. 



There are many kinds of Cinquefoils, mostly natives 

 of the north temperate zone, usually herbs, with compound 

 leaves and yellow, white or purple flowers, always with 

 pedicels; the flat or cup-shaped calyx, with five, main 

 teeth, alternating with five, tooth-like bractlets; petals 

 five, broad, often notched; stamens numerous, with thread- 

 like filaments and small anthers, near the base of the calyx- 

 cup; pistils numerous, on the conical, hairy receptacle, 

 which does not become fleshy or juicy, each pistil maturing 

 into a dry, seed-like akene. Potentilla means "powerful," 

 as some sorts are medicinal. They often resemble Butter- 

 cups, but never have shiny petals, and Buttercups do not 

 have bractlets between the calyx-lobes. 



A dear little plant, forming low tufts, 

 Arctic Cinquefoil 

 Potentilla two or three inches high, with thin, biown- 



emarginata ish stipules, bright green leaves, more or 



Yellow less hairy, and bright yellow flowers, 



Summer deeper in color towards the center and 



Northwest , . . 



about half an inch across. This grows in 



high northern mountains across the continent and in Siberia. 



. ., The foliage of this plant is a lovely 

 Silky Cinquefoil , , , , . , ... A , 



Potentilla shade of silvery gray, which suits the 



pectinisecta yellow flowers. It has several stoutish, 



Yellow reddish, stems, a foot to a foot and a half 



tal1 ' s P rin S in S from dumps of leaves, with 

 long leaf-stalks and five to seven leaflets. 

 The bright-yellow flowers are each three-quarters of an

 with long, thick, white, silky down, particularly on the 

 under side of the leaves. 



This is the only kind of Dasiphora, a 

 Shrubby Cinque- pretty s h ruD , very branching and leafy, 



Daslphora one to ^ our ^ eet ^^h dotted all over with

 altitude of ten thousand feet, and is a troublesome weed in 

 northern New England. It is also found in Europe and Asia.
