This plant was raised in the garden of the Horticultural 

 Society from Mexican seeds, from the Tierrafria, presented 

 by George Frederick Dickson, Esq. It is nearly related to 

 £, heterophylla, but is a much prettier species, without the 

 coarse viscid hairs that clothe all the green parts of that plant. 



It recedes from the character of the genus in not having 



any discoverable pappus, and in the scales of the receptacle 



neither being rigid nor projecting beyond the florets of the 

 disk. 



It is a very showy perennial, growing about a foot high 



has dark - brown 



hardy enough to endure 



pindle- shaped roots, and is probably 



ordinary winter in the open 



border, but it is better to take up the roots after flowering 



name, formed 



in allusion to the sharp points of the scales of the receptacle which bristle over 

 the centre of the flower-heads of some species.
