Corallina officinalis (L.)
Description: This plant is erect, 4-6 cm. high, dark pink in colour, arising from an encrusting basal layer attached securely to the substrate. The erect portion is a branched system of jointed segments. The segments below are cylindrical, about 0.75 mm. diameter; above slightly 
compressed and about 1 mm. broad. The axes are clothed with narrower short lateral branchlets that shorten to the apex. Branching pattern gives the plant a clumpy appearance.
Habitat: On rocks in the lower intertidal and upper subtidal zones and in tide-pools.
Pacific Coast Distribution: Alaska to Mexico.

 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 |
