It is supplied with a system of stout, much- branched rhizomes that vary in diameter from 2 to 8 mm. and extend from just beneath the surface to a depth of from 6 to 8 inches (fig. 50).

From these rhizomes arise large clusters of roots ranging in diameter from 2 mm. to less than mm. These roots descend rather vertically or somewhat obliquely and completely fill the soil to a depth of 25 inches, while some reach a maxi- mum depth of 28 inches. The younger roots are supplied with many branches.
