"With the exception of the present species, and Onychium 

 angustifolium Kze. (our Pellaa decomposita, v. 2. p. 171) all 

 the true Onychia are natives of the Old World. Here how- 

 ever it may be observed that the sori are less decidedly in 

 exactly opposite pairs than is consistent with the character 

 of the Genus. It borders too closely on Cheilanthes, as that 

 does again on Adianlum.
