Lower California. Its altitudinal range is below 3,000 feet, and 

 its habitat the bases of sheltering rocks. It is named in honor 

 of Daniel Cleveland, the earliest resident botanist of southern 

 California. 



Cheilanthes Fendleri Hook. A species of wide distribution. In 

 the Sierra Nevada it extends from Mt. Stanford to San Jacinto 

 Mt., and in the Coast Range from Lake county to Santa Cruz, and 

 it has been collected on the island of the same name. It occurs 

 also in the mountains of the Colorado and Mojave deserts, ex- 

 tending thence into Lower California and Arizona. Its altitudi- 

 nal range is from 3,000 to 9,000 feet, and it grows in the crevices 

 of rocks. 



Cheilanthes myriophylla Desv. is usually credited to 



California, but I have seen no specimens that are not better re- 

 ferred to the preceding species. 



Cryptogramme acrostichoides R. Br. A species of high altitudes 

 in the Sierra Nevada. It reaches us from the far north, and is 

 most frequent in the northern part of the State, but it has been 

 collected in the extreme south, at 9,000 feet alt. in the San Ber- 

 nardino Mts., by Mr. W. G. Wright. This is the southern limit of 

 the species. It also is a rock fern. 



Pellaea Breweri Eaton. On exposed rocks, at high altitudes in 

 the Sierra Nevada, from the Yosemite northward into Oregon. 



Pellaea andromedaefolia Fee. Common from Santa Cruz and 

 Amador counties south to San Diego. The variety rubens Eaton 

 is found in the southern part of the State. It has fronds which 

 when young are somewhat yellowish, and later become bronzy 

 purple or red, a coloration which has been thought to be the re- 

 sult of growth in exposed situations. Both species and variety 

 grow in stony soil in the lower mountains below 3,000 feet alt. 



Pellaea brachyptera Baker. A rock-loving fern growing at 

 high altitudes in the Sierra Nevada. Its reported range is from 

 Plumas county northward into Oregon. 



Pellaea ornithopus Hook. Common on hills or mountain 

 slopes, below 5,000 feet alt., from Mendoceno to San Diego coun- 

 ty, and thence to San Pedro Martir, in Lower California. It 

 commonly grows in clay soil, in the protection of shrubs or 

 stones. 



Pellaea Wrightiana Hook. The form of this fern known as 

 var. compacta Davenp. is frequent in the San Bernardino and
