two leaves and the normal three were to be seen on the same 

 branch. (2). 



Polypodhun Calif ornicum Kaulf. Rather scarce, always in 

 shady or sheltered localities. (36.) 



Gymnogramme triangularis Kaulf. The most widely spread 

 fern, growing luxuriantly in the crevices of rocks with northern 

 exposure, also in very dry sunny spots, but then much reduced 

 in size. (38.) 



NotholcBua Newberry i Eaton. Nearly as common as the 

 preceding and always in places fully exposed to the sun. A 

 form is occasionally found associated with the first, but of a 

 more slender habit and much more finely dissected leaves. (39.) 



Pellcea ornithopus Hook. The more scarce fern on the island, 

 seen only at the eastern side on basaltic rocks fully exposed to 

 the sun. (37.) 



Parmelia physodes L. var. enteromorpha Tuck. Exclusively 

 on dead branches of cypresses. (48.) 



Usnea barbata L,. Growing on the living trunks of the 

 palms, only on side facing the sea. (49.) 



Ramalijta homalea Ach. On rocks facing the sea among the 

 palm grove, on the western side. (50.) 



Physcia sp. ? Shady places in various parts of the island. (52.) 



For the identification of the above mentioned species I am 

 indebted to Mrs. Katharine Brandegee; for the lichens to Prof.
