NATURAL HISTORY OF PLANTS. 



Western Asia.' They have alternate pinnatifid leaves, much dis- 

 sected, with narrow segments ; in X. damuHccena they are transformed 

 into bracts, and form an involucre below the calyx (figs. 25, 26). 

 The flowers are solitary, terminal. 



The Ni(/ell(e, therefore, differ chiefly from the Columbines in the 

 more or less complete union of their carpels, in the peculiar arrange- 

 ment of their stamens, and in the opposition of the petals or 

 nectaries to the sepals. The Hellebores* differ still less from the 



NigcllfP, for if we ex- 

 cept the difference of 

 habit and growth, we 

 find that the only 

 want of resemblance 

 between the two types 

 is in the form of the 

 petals or nectaries, the 

 degree of cohesion of 

 the carpels, and the 

 organization of the 

 ovules. We may con- 

 vince ourselves of this 

 by analysing first the 

 common Bear's-foot

 Pied de Griffon).
