LEAF. Cauline, simple, sessile, exstipulate, feath- 

 er-veined, serrate, oval-acute. 



STEM. Erect, round, herbaceous. 



This is the last inflorescence schedule, and future 

 descriptions of this part of plants will be made with- 

 out the help of questions. There are some obvious 

 characters of the inflorescence, easily understood and 

 described, that have not been named in the schedule, 

 and, that they may be noted in future descriptions, 

 we call attention to them here. 



When many flowers are crowded upon a rachis, or 

 receptacle, the cluster is said to be dense ; but when 

 they are few and scattering, it is said to be loose. 



The bracts of a cluster may be very numerous, or 

 they may present peculiarities that a child can easily 

 describe, such, for instance, as relate to shape or 

 color, or they may form an involucre at the base of 

 the cluster, and these points might well be included 

 in a description.
