No. 2. Notes on the Ferns of the Channel Islands. 9 



anomalous floral peculiarities of the archipelago, and 

 more particularly to the Island of Santa Cruz. 



During a recent short stay upon the Islands the 

 writer made a discovery which adds another to the 

 many curious facts in relation to the flora of these 

 Islands which have already been recorded, having 

 found Polypodium Scouleri, H. & G„ growing luxur- 

 iantly among the projecting fragments of volcanic 

 rock at the mouth of one of the most interesting caves 

 on the island. This fern has not so far as I know, 

 been reported south of the neighborhood of the Bay 

 of San Francisco, nearly 300 miles north from this 

 island, except in one instance, where Dr. Palmer re- 

 ported it from Guadalupe Island, off the coast of Mex- 

 ico, several hundred miles south. 



In May, 1887, I published the occurrence of Cheil- 

 anthes myriophylla, Desv., on Santa Cruz Island; the 

 specimen was collected by Prof. H. C. Ford. This 

 seems to be the northern limit of this tropical species, 

 thus furnishing another illustration of the peculiar over- 

 lapping of species noted in my article on ferns in 

 "Santa Barbara As It Is." 



In the spring of 1887 Prot. Ford made some collec- 

 tions on Santa Cruz Island, of which some of the 

 ferns were given to me for determination, and I be- 

 lieve the first published notice of the ferns of these 

 Islands was that of Cheilanthes above referred to. 



Later in the same year Prof. Greene published the 

 results of his collections. In 1888 Mr. T. S. Bran- 

 degee, in an article published in "Proceedings of the 

 California Academy of Science," 1889, added three 

 more species to. Prof. Greene's list. 



In August of the present year, during a stay of a 

 few hours upon Santa Cruz Island, Prof. H. C. Ford 

 and myself collected or noted all the species noted by 

 former collectors, excepting four species, and found 

 one additional species (Polypodium Scouleri) ; we 

 found fronds of Cheilanthes myriophylla growing to a 

 height of over 20 inches.
