Except for specimens from the vicinity of San Pedro and La Jolla, California, actual herbarium records of Pelagophycus are few. This is largely due to the excessive size of the plant which makes preparation. Figure 3. Pelagophycus porra. A complete plant of medium size collected and photographed by W A. Setchell at San Pedro, Calif., in 1895. Note the numerous blades, small holdfast and spherical vesicle giving rise to cylindrical "antlers".
