An allied species is C. ovalifolia (CAL) Jaeg., an cores 
plant; a much misunderstood species, often confused with C. dilatata. 
It has more widely spreading leaves, very broadly rounded at apex, 
and with nerve tapering above, and ceasing decidedly lower i in the leaf. 
To this species a certainly be reduced C. crenulata Mitt., and C. 
squarrosula Hampe; I have examined authentic specimens of both

here more or less distinctly toothed. The toothing may be faint, but 
is more often very pronounced and even coarse. It is usually confined 
to the lamina, margin, but the broad, stout, rigid arista formed of 
the wide, excurrent nerve is sometimes itself toothed. The differences 
in the foliage leaves described, though slight, are I think fairly con-
