100 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 26 



Type locality: Pacific Grove, California. 



Mexican distribution: Pacific Baja Calif. — Cooper 530a, 

 3/5/47, Playa Rosarita; D. 286, 4307, vicinity of Punta Descanso; D. 

 1138, 1301, 8878, Punta Baja; D. 1444, Punta Santa Rosalia. 



This northern species appears to be confined in Mexico to the 

 coldest upwelling areas of northwestern Baja California.

 Gardner 1927, p. 241; Dawson 1960, p. 51. 



Thalli 8-12 cm. tall or more, apparently usually saxicolous, mem- 

 branous, consisting of irregularly subdichotomous to subpalmate 

 branched or divided blades, the segments 7-12 mm. wide, 1.2 cm. long, 

 without a midrib, but with microscopic longitudinal veins, monostro- 

 matic in upper parts except at the veins ; tips rounded, sometimes broad- 

 er just back of tips than a little lower down; margins entire or beset 

 with small, elliptical, pedicellate, flat bladelets; tetrasporangia in small, 

 rounded, solitary sori in marginal bladelets; sexual plants not seen.

Type locality: San Pedro, California. 



Mexican distribution: Pacific Baja Calif. — D. 13231, Islas 

 Todos Santos, 38 m. 



Only a few other collections of this sublittoral species are known. 

 Gardner recognized a collection from off Santa Barbara, and we have a 

 recent tetrasporangial one from Goleta Pass, Calif., at a depth of 16.5 

 m. (D. 16020) that corresponds very closely with Gardner's specimens. 



Cryptopleura crispa Kylin 



PI. 49, fig. 2 

 Kylin 1924, p. 90, fig. 77; Dawson 1945, p. 67; Dawson 1950b, p. 68; Dawson 

 1951, p. 53; Dawson, Neushul & Wildman, 1950, p. 56. 



Thalli epiphytic, consisting of a prostrate membranous system at- 

 tached by rhizoids (this often several cm. in extent) giving rise to 

 branched, ligulate free blades 3-8 cm. long or more and 3-4 mm. wide or 

 more; blades at first prominently marginally undulate, then the undula- 

 tions becoming congested, and crisped, at maturity showing a strong 

 basal midrib (the blade margins often partly eroded away) and pro- 

 gressively fainter veins above; tetrasporangial and spermatangial sori 

 borne in the crisped marginal processes; cystocarps irregularly scattered 

 over the thallus surface.

 ium, Lund, Sweden.
