undoubtedly to the CicJioracew, agrees in every respect, 
both in habit and character, with Xerantliemum, except in 
the florets being all ligulate. The anthers, although not 
bicaudate at the base, cannot be regarded as entirely naked, 
being furnished with two small teeth. This is more dis- 
tinctly observable in Scolymus^ which, although belonging 
.to the CiclioracecB^ has the habit of Carlina. The genus 
JTeranthemum, therefore, brings these three groups close 
to each other, as it were, at right angles. 
Although divisions in the extensive class of Composites 
a^e absolutely necessary, in order to facilitate a knowledge 
of the genera of which it is composed, yet, by the forego- 
ing remarks, I have endeavoured, and I trust satisfactorily, 
to shew that these divisions are to be regarded in no other 
light than as artificial; but although artificial, we must 
mvoid the unnatural division of genera. Keserving to a fu- 
ture time the observations I have to make on the other 
groups of Compositce, I shall now proceed to give charac- 
ters of the genera I have to propose, adding at the end of 
bach such remarks in elucidation as may appear necessary,
