ASPLENIUM TRICHOMANES. 



that I detect are the more distant three pairs of basal pinnae, 

 the more equal sized and shaped pinnae, and the minutely- 

 crenate margin. A pretty form, of some four inches in length. 

 I am indebted to Mr. Willison, of Whitby, for fronds. 



Majus, Hort. — A large-growing form found in Devonshire, 

 and in County Clare, and other places. It is of the normal 

 form, with fronds from twelve to eighteen inches in length. 

 I am indebted to the Eev. C. Padley, of Beaconfield, near 

 Plymouth, for a number of Devon fronds, and to Mr. Foot, 

 of the Geological Survey of Ireland, for others from County 

 Clare. An illustration is unnecessary. 



CuNEATUM, Lowe. — Raised from spores at Highfield House. 

 Length of frond three inches. The pinnae are elongate- 

 triangular, broad and flat at the apex, and cuneate at the 

 base. The margin serrated. The ultimate pinna three times 

 the size of the others. 



There are yet seven varieties that I have been unable to 

 get a sight of, namely: — Abruptum, Moore; bifurcum-ramosum, 

 Moore; crenuto-ramosum, Moore; dichotomum, Moore; inciso- 

 lohatam, Sim; lobatum-ramosum, Moore; and rariatis, Moore.
