Physical Description

Diagnostic Description

Aster is a large and difficult genus, and there are three other species similar to A. simplex. Aster hesperius and A. eatonii have involucral bracts that do not strongly overlap and are in 1-2 series. Aster chilensis has involucres that are 5-7 mm high. A hand lens is necessary to distinguish these characters, and a technical key should be consulted.
