blunt, simple, terminal segments. Narrow forms may usually be dis- 

 tinguished from broad forms of C. violacea by the tips, which are not 

 incised into acute, small segments as in the latter species. 



Our material has been compared with the type in Herb. Agardh 

 which consists of two cystocarpic specimens. The larger one of the two 

 is about 25 cm. high with segments about 0.8-1.4 cm. broad. The smaller 

 example was well figured by J. Agardh in 1879 (see fig. 82). Tran- 

 sections of these specimens show the thickness to range mostly between 

 250 /x and 380 /*.

Setchell 1923, p. 399. 



Type: Holotype is a cystocarpic specimen, probably collected by 

 C. L. Anderson, on sheet 367783 in the Herbarium of the University of 

 California, Berkeley. 



Type locality: Santa Cruz, California. 



As pointed out above, this should probably be reduced under Cal- 

 lophyllis marginifructaj for the aggregation of the cystocarps mostly "on 

 tips of lateral lobes" appears to be more accidental than genetical.

Type : Holotype is M. Doty 2594 on sheet 306925 in the Dudley
