A careful study of C. niucronafinn will probably show a very 

 decided variation in the size and occurrence of the mucrouate tip 

 of the utricle. In the plants included under the preceding form, 

 all studied l)y ns have the typical tip of the f. Californicum. In 

 the plant quoted under the present form, the mucrouate tij) to 

 the utricle is to 1)e found only in the very young i)ortions of the 

 frond. Below, in the older portions, the utricles are more or less 

 swollen at the tip, as in C. Muelleri Kuetzing, and while some of 

 them show a very slight a])iculus, the majority of them do not. 

 The ])lant certaiidy differs from the more usiuil foi-m on the 

 Pacific Coast of North America.
