exposure, also in very dry sunny spots, but then much reduced 
in size. (38.)

Pellea 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 1. var. enteromorpha Tuck. Exclusively 
on dead branches of cypresses. (48.) 
Usnea barbata I, Growing on the living trunks of the 
palms, only on side facing the sea. (49.) 
Ramalina homalea Ach. On rocks facing the sea among the 
palm grove, on the western side. (50.)

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