Gracilaria foliifera, an agar-yielding red alga, occurs from New England to the tropics and exhibits much morphological variation. Plants weighing 5 g increased 14-fold in 20 days in Alligator Harbor, Florida, and 15-fold in Beaufort Harbor, N. C., during the summer. From 43 to 57 per cent of the dry weight consists of agar-like cell wall polysaccharides with a gel strength of 1/7 to 1/3 that of Difco agar. Samples from Virginia, North Carolina, Florida, and Texas are compared with respect to physical properties. Gracilaria lacinulata is regarded as a distinct species.
