In many cases it is most difficult to determine tlie species of this genus, and errors often occur : this 
agrees with a specimen of .4. infesta in Sir "W. J. Hooker's Herbarium.

The present specimens arc nearly destitute of fructification, and with the broad laciniiB present a dif- 
ferent appearance from my original specimens of ^. elongata; nevertheless I beheve that I am right in 
referring them to this species.

In a note respecting this species in my ' Genera of Perns' I have made the foUowing observation : " This 
species differs in habit from the rest of the genus, having more the appearance of a large roli/poJium^ but 
' the sori being furnished with articulated hairs, and the receptacle slightly elevated, induce me to retain 
it here." Sir W. J. Hooker, in the 'Species Pilicum,' remarks that "in habit and appearance this is ex- 
tremely distinct from any other AJso2)Jnla, and the receptacles are very slightly elevated, so that it must be 
considered but a doubtfiJ species of the genus." Presl notices it as differing from the rest of the genus in 
not being arborescent ; but this can only be while in a young state, for in the ' Species Pilicum' it is de- 
scribed as attaining the height of 8 feet, and, judging by the gro\\-th of livmg specimms in the Koyal 
Gardens at Kew, I have no doubt that in time, and under favourable eircumstauces, it may attam that 
hel-rht ; but while increasing in height it also produces numerous offsets from the side of the stem, which
