VOL. 1.] Plants of Santa Catalina Island. 113 
CASTILLEIA FOLIOLosA H. & A. Plants as tall, as woody and 
as white as C. hololeuca Greene of Santa Cruz, the pubescence that 
of the form common on the mainland which on the bluffs about 
Del Mar in San Diego county grows equally tall and stout. 
The following list contains only such species as were not noted 
by Mr. Lyon. The writer is under many obligations to the resi- 
dent botanist of the island, Mrs. S. A. P. Wheeler, who, previous 
to his arrival, had collected many of the species mentioned below; 
and to Mr. Harry Polley, not only for information concerning plants 
and the topography of the island, but also for his unwearied assist- 
ance in the field:
