Remarks
Etymology: Just below the surface of the soil the root becomes abruptly enlarged to form a fusiform or narrowly ellipsoidal mass of fleshy storage tissue. A single sparsely branching stem arises from the summit of this thickened portion of the root and the slender simple taproot continues down from its base. It is unique in the genus.
