Description of the species. In a well grown individual the 

 stem is a stout cylindrical trunk arising from tlie top of a hemi- 

 spherical or compressed conical root, which measures 2-ocm. in 

 diameter. The average length of a frond measures o.;j-4 feet 

 but frequently as much as 8 feet. The stem, in most cases, 

 sends out numerous branches at a distance of a few centimeters 

 from the base. These branches divide repeatedly, resulting finally 

 in a number of subordinate branches. 



The stems of the youngest principal branches are cylindrical 

 and smooth on the lower portions but above become gradually 

 compressed. Coarse spinous processes are usually present on the 

 margins of the complanated portions of the stems. The leaves 

 on these stems are thick, coreaceous, dark-brown, oblongo-ovate 

 or spathulate, slightly elevated at the costal region, and irregu- 

 larly and roughly serrated on the margins.'' As in the preceding 

 species, the subordinate branch grows out from the upper surface
