DESCRIPTION:
California arrowhead, an annual aquatic plant, is common in wet areas throughout California's interior valley. Submersed seedlings are similar to Gregg arrowhead. Seedlings have narrow, succulent, light green leaves that taper to a blunt point. Rectangular-shaped markings on leaves help to distinguish these seedlings from ducksalad and bulrush. Distinctive arrowhead leaf shape does not appear until the third or fourth true leaf. The flower stalk, with leafless stems, does not grow above the leaves.
