In general, this variety can be distinguished by its short, some- 
what truncate mature calyx, its long-petioled, more or less lyrate 
lower leaves, and the sessile floral ones, which are white-villous 
below. Тһе corolla, usually, is much smaller than in the species. 
The same characters will generally separate it from the var. 
depauperatus with which it might be confused.
