660. Phyllospadix, Hook., Fl. II., 171. (False Eel-Grass)

(2454.) P. Scouleri, Hook., Fl. II., 171.

Abundant on steep rocks below half tide, from the lighthouse, near Victoria, around the coast to Esquimault Harbor; very common in the same situations on all the islands in the outer part of Barclay Sound, on the west coast of Vancouver Island. (Macoun.)

Although much like Z. marina in general appearance, its place of growth differs so materially that the two species need never be confounded, as this always grows on steep rocks or on boulders, while the other delights in pools with a bottom of shell mud. Fine fruiting specimens were obtained in July and August, 1887. It is very likely quite common on the Pacific coast, but usually confounded with Z. marina.
