214 SEA MOSSES. 



Ahnfeltia gigartinoides, Ag. 



This plant is found only on the California coast. 

 It is reported not common at Santa Cruz and quite 

 rare at Santa Barbara. It is a more robust and, by 

 far, less profusely or irregularly branching plant, than 

 the last. 



The specimens in my herbarium are six inches 

 high, some of them rising for three inches in a 

 single cylindrical stem, and then forking regularly and 

 evenly in one plane six times, giving sixty-four ter- 

 minal j)oints to the plant. Others fork fewer times, 

 and less widely, and nearer the bottom of the stem, 

 and then stretch out in long segments two or three 

 inches, before they divide for the second and third 

 time. Like the other, it does not adhere to paper, 

 and its substance is hard and homy when dry. 

 Color, a dark red.

The purple Cystodonium is a very common, some- 

 times a provokingly common, coarse, bushy, and 



• Cystoclonium = Bladdery branches.
