however, is also the case in E. Domingensis,) 

 and in the greater quantity and density of the 

 albumen, which is between fleshy and cartilagi- 

 nous. 



The authors of the " Flora Peruviana" have 

 reformed the character of Echites, but the scales 

 which they describe between the calyx and 

 corolla will certainly not materially assist in 

 distinguishing this genus from those most near- 

 ly related to it ; and I have observed, a nearly 

 similar structure in most of the genera of this 

 family, as well as of Asclepiadeae : these scales, 

 however, truly belong to the calyx, and are 

 either five or ten in number, or more rarely 

 consist of an uninterrupted series of cilise, not 

 unlike those which so frequently occur within 

 the footstalks of the leaves. My observations 

 are not sufficiently numerous to enable me to 

 determine whether their modifications might 

 not generally assist in characterizing genera, 

 and I have, therefore, very seldom had recourse 

 to them.
