Stems i°to 2° high, usually bearing a few small laciniate bracts, 

 glandular-puberulent or pubescent, or even slightly villous, espe-

 scattered, pale, yellowish hairs ; petioles i' to 3' long, not slender, of- 

 ten grooved or fluted, villous with short yellowish hairs which are 

 continued upon the larger veins on the lower surface of the leaves ; 

 leaves thin, sometimes purplish underneath when dried, i' to 2' 

 broad, round-cordate with a deep but usually rather narrow 

 sinus at base, hardly lobed, crenate, mucronate-dentate, margin 

 ciliate, upper surface glaucous, or that of the younger leaves 

 pubescent; calyx at time of flowering short campanulate, broad, 

 open, i" to I yi" long, lobes short and obtuse, pulverulent, the base
