however so much m the technical character of the sori, that, as shown by its synonyms, it has been placed 
by the respective authors under different genera ; sori agreeing mth the technical character of each of the 
three genera being found on the same frond, or on different fronds of the same plant. This and many 
other examples of son characteristic of these genera being often produced on the same plant, shows that 
the binate sori of Diplazium, and the opposite coalescing sori of Scolopendrium, are scarcely tenable as 
generic distinctions ; :md there being no natural character to assist in defining ScoUpendrium and Dijplazium 
as distinct from As^lenium, It appears to me that the whole may with propriety be viewed as forming but 
one extensive natural genus, consisting of groups of species, more readily distinguished by their different 
phases than by any characters derived from the sori.

If we restrict Asplcmum fonfanum to its European type, then the present specimens may have some 
right to be considered a distinct species ; but intermediate forms being found in the Himalayan and other 
regions, renders it Impossible to view the whole otherwise than as one species.

This plant belongs to a grade consisting ot Aspidium cicufaruim, Sw-, from the "West Indies, A. sinu- 
atiim^ Gaud., of the islands of the Pacific, and A. coadunatum, "SVall-, from India. These being described 
by their respective authors as dititinct species^ and coming from different countries, may be viewed as 
good evidence that they are truly distinct species, and which is further confirmed by the different appear- 
ance of cultivated plants originally received from the three localities above mentioned, but on collating the 
numerous specimens in the Hookerian and my own herbarium, it becomes difficult to separate them as 
distinct species,
