The uppermost node on which roots occur, at the base of the culm, may be above soil level, and the roots may not penetrate the soil but appear as short pegs protruding from the stem.
At each node, a root arises from one of four quadrants, which may be designated X (the quadrant centred on the midrib of the leaf attached at that node) Y, A and B.
In the deeper regions of the soil, the anatomy of the nodal roots is similar to that of a seminal root.
