A group of western forms, on the plains from Minnesota to Texas, is perhaps to be 
referred here, but certain differences suggest the possibility of segregation. The 
leaves are thicker and strongly reticulated, as in C. curtissii, and two types of fruit 
are represented—one with very broad corky ribs and narrow intervals, the other 
with ribs and intervals as in true C. maculata but with fruit almost orbicular, Our 
material is insufficient for any more definite reference, and the problem i is commended 
to the botanists of the region.
