248 DESCRIPTION OF ASTERS; DIVARICATI 
same herbarium under both names, sometimes first labelled 4. 
corymbosus because white-rayed and sharp-toothed ; and then re- 
labelled A. macrophyllus because hispid and large-flowered ; in 
reality highly unlike either. The plant also resembles A. con- 
spicuus somewhat in aspect and leaf-form, in size of heads and rays, 
and in roughness ; but differs in developing a cordate base (though 
such leaves are apt to be gone at flowering time). 
Shaded cliffs and woods, of rare occurrence.
