648 University of California Publications in Botany [Vol.8 



5-8 m. long, 2.5-3.5 cm. broad, densely covered on both sides with short 

 blunt tubercles, and along each margin with outgrowths bearing the 

 ellipsoidal bladders and smooth ovate or spatulate sporophylls among 

 the sterile leaflike structures; blade in the young specimens coarsely 

 rugose, conspicuous, but soon lost. 



Growing in the upper sublittoral and lower littoral belts. From 

 the southern end of Vancouver Island to Point Conception, California.

This plant is often very long, with several branches arising mostly 

 near the base as outgrowths which, unlike those of the sporophyll type, 

 have lateral blades, transition places, and lateral outgrowths in turn, 

 developing like the main stipe and rhachis. The bladders are frequent 

 but develop in no exact order. 



Egregia laevigata Setchell 



Holdfast and stipe much as in E. Menziesii, but the true stipe and 

 the rhachis smooth on both sides, the marginal outgrowths very 

 variable in different individuals and at different ages of the same 

 individual, some profusely dissected and filiform, even capillary, others 

 large, linear and entire, up to 15 em. long; the bladders varying in 

 shape from spherical to very narrowly ellipsoidal. 



Growing on rocks in the lower littoral and upper sublittoral belts. 

 Extending from the vicinity of Point Conception, California, to some 

 unknown locality on the west coast of Lower California, at least as 

 far down as Ensenada.
