Root, fibrous, finally woodyish. Branches, in very old plants some inches long, and numerous, forming a fine tufted plant; in young plants none at all for many months. Leaves, connate at the base, ringent when young, resembling the gaping jaws of a small quadruped, the denticulations on each side representing teeth, when old, the leaves expand, or even recurve, all the leaves are very glaucous, glaucous, only about a fourth part as large as any of the three last described species, and often roughly punctate. Punctures, lucid, rather elevated into small tubercles than sunk in the body of the leaves, whence a roughness is frequently, not always perceived on the surfaces of them. Flowers small yellow.
