knowledge is from Amador county. Its usual place of growth is 

 in rock crevices, but rarely it is found in soil. 



Polypodium Scouleri Hook, and Grew In the redwood belt of 

 the coast, from Santa Cruz county north to Vancouver. It has 

 also been collected on the islands of Santa Cruz and Santa Rosa 

 and on the Mexican island of Guadalupe. Usually it grows on 

 the trunks of trees, but sometimes among rocks. 



Gymnogramme triangularis Kaulf. Common at low altitudes, 

 from Cape San Lucas, Lower California, to British Columbia. 

 The more robust form, having fronds coated with yellow powder, 

 is the commoner. This is commonly known as the golden fern. 

 The form coated with white powder is called the silver fern. This 

 form even reaches the borders of the Colorado desert, at Palm 

 Springs. The variety viscosa Eaton, characterized by its more 

 contracted and less divided fronds, which are viscid., and either 

 yellow or white powdered, is confined to the coast mountains of 

 San Diego County. It has been proposed recently to raise 

 it to specific rank. These ferns grow in loose, stony soil, on 

 shaded hill sides. The gold and the silver forms usually do not 

 grow together. 



Notholaena Newberryi Eaton. Cottony ffrn. Abundant in 

 crevices of rocks, and about their bases, in the hills of the coast 

 mountains, up to 1,000 feet alt. First collected by Professor New- 

 berry, whose name it bears, in San Diego. Apparently it does not 

 extend north of Los Angeles. San Bernardino is its inland limit, 

 except for a recent collection by Brandegee, at Providence Mts., 

 in the desert region. In Lower California it has been found on 

 Guadalupe Island, and may be expected on the peninsula. 



Notholaena Parryi Eaton. A species of the desert region of 

 Southern California, thence extending to Maricopa in Arizona, 

 and to southern Utah, where the type was collected in 1874, at 

 St. George, by Dr. C. C. Parry. It is found as high as 3,000 feet 

 alt., but is more abundant at lower altitudes, as at Palm Springs, 

 500 feet alt. It grows at the base of rocks or in their crevices. 



Notholaena cretacca Leibm. Rare and local in Southern Cali- 

 fornia. The only stations known to me are the vicinity of San 

 Diego, Palm Springs in the Colorado Desert, and Slover Mt., near 

 San Bernardino — the latter being the northern and western limit 

 of the species. It also extends well down the peninsula of Lower 

 California. Its habitat is the crevices of rocks, or the soil at their
