' Dr Boswell in E. B. ed. 3, vol. xii, described many varieties of ferns, and these 
are enumerated in Land. Cat. ed. 9. We have not, however, thought it desirable 
to include most of them, as they were no doubt known to Prof. Babington, and 
rejected by him as unimportant. The vegetative organs of ferns are so liable to 
trivial variations that there is no limit to the number of forms which might Iw 
described.— H. & J. 0.
