Aspleniua Trlchomans s. Linn., @ delicatulum. - Fronds narrower, pinnae much smaller, 
thinner and wider apart than in the normal form. This is a sub-variety, passing 
by intermeddiate states into the typical plant, which\ is the coamon r ol’*‘northern 
Europe. The variety is the prevalent fora in Canada, but also occurs*further south 
in the United States, for I have specimens from Catskill( A.O.Brodie), and is not 
confined to the American continent, for Professor Caruel, the acute author of "Flora 
Italiana" sends specimens of a similar form from Florence. There is an A$p . Trich. 
var. me jus in Cuba(according to Mr. Eaton’s Enumeration of Wright's Cuban Ferns), A. 
,ancepj~j is a Madeiran fora, not distinguishable, so far as I can see, from common 
European states of Trlchomanes. .
