2. The larger number of pairs of hydrothecae to each inter- 

 node. This feature will be quite apparent from the table. In 

 the other species the number is only two or three. 



3. The rather stouter and shorter nodal portion of the stem. 

 Nutting's figures show these much more slender and long. 



4. The tendency in certain stems to form divergent branches 

 from the sides of the internodes, as shown in Fig. 15.

5. The very common and rather distinctive occurrence of ter- 

 minal and lateral stolons on the stems, from which at irregular 

 intervals secondary stems arise. 



It is much to be regretted that no gonangia were present on 

 any of the specimens, as this would have afforded almost certain 

 proof as to the affinities of the species. It may be found that 

 when specimens are obtained from other localities and in larger 

 numbers, though the numbers in the present case were large, the 

 present species will have only a varietal importance. Still, I am
