| The root of this plant is large, fleshy, branch- 
ing, and often somewhat fusiform. It is only by 
comparison with the other species that it ean be 
called tuberous. The stems are numerous, grow- 
ing in bunches from the root. They are erect, 
ascending or procumbent, round, hairy, green or 
red. Leaves scattered, the lower ones peduncu-

oblong, hairy, obtuse at base, waved on the edge,
