 consisting of Roses which display the normal characteristics of the

flowers ; in the others, the number of the leaflets (of the average-sized 

 leaves in the majority of Roses not exceeding from five to seven) is 

 either decreased to three leaflets, as in Section XIV., or increased from seven 

 to nine in Sections XII. and XIII., and from eleven to fifteen in Section XV. 

 Section XVI. consists of a simple leaf, quite exceptional in the genus, and 

 having no stipules. Some of these Roses are still further distinguished 

 by the size of the disc, and by the manner in which the ovaries are 

 inserted in the receptacle.
