Descr. — Root thick, tortuous, black, simple, (and stated in the Linnea to have been seen six 

 inches in length, and abrupt at the apex). The plant is covered with short, somewhat appressed 

 hairs, of a yellowish hoary appearance, which renders it soft and velvety to the touch. Petioles 

 and calyces somewhat villous, but the hairs are more spreading. Stems from 8 to 24 inches or 

 more in height, erect, or ascending, and with few leaves. Petioles of the leaves 2-3, and 

 sometimes 4 inches long. Leaflets large, from 1 to 3^ inches long, and from G to 9 lines 

 broad ; apex obtuse, margin deeply and somewhat obtusely toothed, having the terminal tooth 

 the smallest. Stem-leaves small, and placed on a short petiole joined with the stipules, which 

 are obliquely ovate, acuminate, and generally entire. Flowers from 2 to 20 on each stem, and
