The stipe varies in length from 5 to 50 cm., from 6 to 9 mm. in diameter, is terete, flattening above the base of the blade. The blade is smooth, with or without two rows of bullations, sometimes undulate, and tapered to broadly rounded at the base; it is 12-18 cm. broad and 2.5-3.5 m. long.
Habitat: On rocks in the lower intertidal and upper subtidal zones.

 The Race Rocks taxonomy is a collaborative venture originally started with the Biology and Environmental Systems students of Lester Pearson College UWC. It now also has contributions added by Faculty, Staff, Volunteers and Observers on the remote control webcams. -Ryan Murphy PC yr 26 |
