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, Aulax, (?) Dilobcia, Leucadendron (fig. 
235), Nevenia, Sorocephalus, Serruria, Petrophila, Isopogon, Spatalla, 
and Adenanthus, some African, some Australian.
