With the exception of the present species, and Onychium 
angustifolium Kze. (our Pellcea 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 Adiantum.
