The distribution, seasonal growth and reproduction of in situ populations of Phaeostrophion irreguläre were studied at Glacier Point, British Columbia in relation to a variety of environmenta] factors. The plant is restricted to sandy areas where large fluctuations of sand occur annuaÜy. Typically P. irreguläre is buried four to six months per year, and its growth and reproduction are limited to periods of sand subsidence. Competition with other plants probably accounts for the restriction ofP. irreguläre to sandy areas, äs it will grow in rocky areas if other algae are eliminated. The period of maximum growth (Febr. to April) is associated with a corresponding increase in light intensity and water temperature. After April, growth in non-tide pool populations decreases much more rapidly than growth of tide pool populations, because of increased desiccation during daylight hours. The morphology of laminate plants of Phaeostrophion irreguläre is extremely variable and the ränge of variability at Glacier Point overlaps with that described for^. australe from California. The latter plant is considered to be a growth form and a taxonomic synonym of P. irreguläre. Distributional evidence also Supports this conclusion, äs there is no marked geographical discontinuity between the t wo plants. Phaeostrophion
