The species of Scalesia form a very natural genus, and all those now to be 
described agree in every essential particular with the generic character, drawn 
up by Arnott from an examination of S. atractyloides alone. The flowers of 
the ray in some have ligulate corollas, but they are neuter, and such species 
are here grouped together. The division of the style is a variable character ; 
it has long arms in some of the flowers and is very short in others. Judging 
by Mr. Darwin's excellent specimens, this and the following species appear 
very distinct from one another. The habit of the present is rather different 
from the rest.
