 Potentilla anf l ' ea f ! the latter is composed also of 



Norvegica three leaflets instead of five, and it slightly 



Yellow suggests the strawberry leaf. The five 



Se"tember not very conspicuous petals are somewhat 

 isolated in the green setting of the flower, 

 which is very leafy in character. There are 15-20 sta- 

 mens. 12-30 inches high. In dry or waste ground, 

 from Me., south to S. Car., and west. The name is 

 from potent for the plant's reputed medicinal powers.

Cinquefoil istically rough, horned seed-vessel. The 

 Potentilla recta five rather narrow leaflets are deep green, 

 Yellow very hairy beneath, and slightly so above.

 lobes of the calyx (flower-envelop), which is the reverse 

 of the case with the Norway cinquefoil. Erect, 1-2 feet 

 high. Adventive from Europe, and in the vicinity of 

 old gardens and waste grounds. Me., south to Va., arid 

 west to Mich. Found at Exeter, Penobscot Co. , Me.

 Silvery y character. The leaflets are dark 



Cinquefoil

Yellow white wool, beneath which appears the 



pale terra-cotta tint of its surface. The 

 five wedge-shaped, narrow leaflets are 

 rolled back at the edge, and quite deeply cut. The pure 

 yellow flowers are rather small, and loosely clustered at 

 the ends of the branches. 5-12 inches long. In dry and
