{e.g., S. acutiloba, S. Zeijheri, S. micrantha, and S. inter media). 

 The stigma is either exserted or included in the tube, but, except 

 in the small group Brevistijlae, is always situated above the 

 anthers. 



The genus can be subdivided into two well-marked sections 

 according to whether the flowers are tetramerous or penta* 

 merous. These sections correspond in part to the subsections 

 Tetrandria and Pentandria, Schinz, of the section Eusebaea, 



et seq.).

The section Pentandria, however, has been enlarged to include 

 Schinz's section Belmontia (v. Schinz in Bull. Herb. Boiss., 

 ser. II., vi., p. 721), since the distinction between the sections 

 Pmsebaea and Belmontia seems somewhat of an artificial one. 



In the Flora Capensis the enlarged section Pentandria has 

 been subdivided ; annuals are separated from perennials, and 

 certain peculiar forms are kept apart as they appear to form 

 somewhat isolated subsections. For convenience, and also to some 

 extent in accordance with affinity, the subsections Annua?, 

 Perennes and Repentes are broken up into smaller groups.
