The habit of the little plants of the genera Grangea, Cotula, 

 Centipeda and Sphceromorphsea are very similar. Sir J. D. Hooker 

 states that Centi^yeda and Sphseromorphsea should be placed near 

 Grangea, i. e. in the Asteroidese ; Cotula also seems closely allied to 

 Grangea, both having stipitate cypseles.
