Mrs. Lemrnon's Nos. 6 and 7 are perhaps forms of P. Orni- 

 thopus while Mr. Burnham's No. 5 is probably C. myrio- 

 phylla. Miss Hutching's adds Cryptogramme acrostichoides, 

 Cheilanthes Cooperae and Gymnogramme triangularis. 

 The last is represented in two forms, No. 20, the common 

 one known as " Gold Back," and No. 21 which is called " Sil- 

 ver Back." This last certainly deserves a botanical name 

 as well as its distinct common name. Cheilanthes Cooperae 

 did not come from the valley itself but from the hills lower 

 down. 



Mr. Congdon in Zoe, iii, 325 gives the following from 

 Yosemite Cliff: Cheilanthes Californica; Pellaea Breweri; 

 P. densa; P. Bridgesii; and Cryptogramme acrostichoides. 

 He also adds Aspidium Nevadense without giving exact local- 

 ity. This is probably an error since it seems to be limited 

 to the northern Sierras.
