56 ADIANTUMS. 



truncate, glabrous, pinnules gradually smaller as the apex of the 

 frond is approached. Sterile fronds coarsely serrato-dentate. 



Rachis fusco-pubescent. Stipes dull black, minutely muricato- 

 scabrous. 



Sori semi-oval, generally confined to the superior margin; 

 when the sori extends round the point the apex becomes very 

 obtuse. 



Introduced into the Royal Gardens, Kew, by Mr. N. Wilson, 

 in the year 1844. 



It is in the Fern Catalogues of Yeitch, Jun., of Chelsea; 

 Parker, of Holloway; and A. Henderson, of Pine-apple Place. 



I am indebted to Mr. Pass, gardener to T. Brocklehurst, 

 Esq., of The Fence, near Macclesfield, for a plant and fronds 

 of this species. 



The illustration is from a frond forwarded by Mr. Pass. 



In concluding the Adiantums it will be necessary to offer 

 a few words regarding two or three species that have not 

 been figured, and in doing so it seems desirable to give a 

 list of the Adiantums described by Sir W. J. Hooker, in his 

 "Species Filicum," although many of them have never been 

 brought to England in a living state. These Ferns are here- 

 with given with the numbers they bear in Sir W. J. Hooker's 

 work. Those marked thus * are figured in the present volume, 

 and consequently cultivated in this country.
