Next to Protea come a pretty 

 large number of genera, of analo- 

 gous structure at bottom, which 

 mostly formed part of the genus 

 Protea at one time, and have 

 been separated therefrom by 

 modern botanists. The charac- 

 ters in which they differ are 

 but of secondary importance, 

 viz. : — the arrangement of the 

 inflorescences, the form of the 

 perianth and its mode of dehis- 

 cence on anthesis, the diclinism 

 of the flowers, the form of the 

 stigma, the form and consis- 

 tency of the fruit. The genera 



are, Leucospermum, Mimetes, Atdaw, (?) DUobeia, Leucadendron (fig. 



235), Nivenia, Sorocephalus, Serruria, Peirophila, Isopogon, Spatalla, 



and Adenanthus, some African, some Australian.
