to the angles of the stem, at once distinguish it from all 

 the allied species even when it is out of flower. Its 

 nearest ally is S. hirsuta, Linn., from the south-western 

 portion of Cape Colony, and one of the most interesting 

 features connected with the plant now described is that 

 its habitat should be separated from that of the older 

 species by a distance of six hundred miles. Like other 

 members of the genus, S. Gettleffii requires a well-drained 

 soil, and very little water should be supplied during the 

 winter months.
