138 Class XIII. Order VI. 



three lobed, remote, the terminal one deeply cleft, appearing 

 like three distinct leafets, so that the leaf has a pinnate form. 

 Peduncles a little angular. Calyx spreading, hairy underneath. 

 Petals longer than the calyx, transparent at base. Nectary obo- 

 vate. Perennial. 



RANUNCULUS BULBOSUS. L. Bulbous crowfoot. Buttercups. 



Calyx reflexed ; flower stalks furrowed ; stem 

 upright, many flowered ; leaves compound. L. 



Very frequent among the grass in pastures, road sides, Sec. 

 The root is solid and fleshy, acrimonious and almost caustic. 

 Stems erect, furnished with leaves, somewhat hairy. Leaves 

 hairy, in three or five principal divisions, variously toothed and 

 cut. Flower stalks upright and furrowed. Flowers of a bright, 

 glossy yellow ; calyx leaves bent downward against the flower 

 stalk, hairy. Fruit in globular heads. May and after. Peren- 

 nial. 



RANUNCULUS ACRIS. L. Tall crowfoot. 



Calyx spreading ; flower stalks round and 

 even ; leaves in three divisions with many seg- 

 ments, the upper ones linear. 



Distinguished by its superior height, being usually about 

 two feet high. Root fleshy, resembling the last, but smaller in 

 proportion to the plant. 'Root leaves large, hairy, divided into 

 three or five diverging lobes, which are again repeatedly sub- 

 divided, ending in acute segments and teeth. Petioles hairy, 

 especially at their ends. Uppermost leaves in three entire, 

 linear segments. Stem erect, branching. Flower stalks round, 

 not furrowed. Calyx spreading under the petals, not reflexed. 

 Petals large, shining, yellow. Seeds in globular heads. This 

 plant spreads rapidly, and is exceedingly troublesome in mea- 

 dows and mowing ground. Being cut with hay, it would no 

 doubt be pernicious to cattle, were not its acrimony lost by 

 drying. It flowers all summer. Perennial.
