Var. Senticulosa (Harv.) nov. comb. Setchell & Gardner, 
1903, p. 327, as P. senticulosa. Esquimalt, Harvey; Orcas, 
Quail cum, Victoria, Macoun. Extreme forms of the variety 
seem quite distinct from typical P. urceolata f but they pass into 
each other so frequently that P. senticulosa cannot be main- 
tained as a species. 
^-T'he genera Schizoneura , Erythroglossum , Apoglossum and Pteridium are segre- 
gates of the old genus Delesseria , and their values as well as the names they should 
bear, are still uncertain.
