and original description : 
* Clammy-hairy, odorous, copiously glandular when young, 
somewhat so at maturity. Stem 3 ft. high or less. Basal leaves 
in close colonies, coriaceous, the earlier ones cordate-quadrate, 
low-serrate, the sinus deep, narrow; the later or winter leaves 
elliptic, long-petioled, often prostrate, often 5 in. lon tem- 
leaves chiefly orbicular and not cordate, with short, broadly

Roe black, thick and contorted, with short internodes. 
Surculi from them are mog and vigorous ; old ones are brown and 
comparatively. slender, 8, in. thick or less, pulling up for 12 in. 
or less ; young runners are white or slightly purplish, succules- 
cent, growing 8 or g in. long in one season, with nodes about I 
in. long. Runners just forming, while only half an inch long, are 
sharply acuminate. Root-fibers also reach 8 or 9 in. long. When 
growing among rock-clefts the horizontal rootstock becomes 
deeply buried and slight, the principal part a thick vertical ppi 
rising I or 2 in., or sometimes even 5 in. above the soil, =f; in. 
thick or less, fleshy and purplish. 
Stem brown, terete, roughened till late with close remnant- 
bases of short glandular and strigose hairs, deeply and profusely 
branched.
