 By Thomas Moore, Esq., F.L.S. &c. 



These notes are the result of an examination of the Ferns of the 

 Wallichian herbarium, with the view in the first instance of deter- 

 mining the genus Prionopteris of Wallich, cited by both Presl and Fee, 

 but evidently without any knowledge on the part of either of those 

 botanists of the plant on which it was founded. Prionopteris Far- 

 quhariana. Wall. Cat. No. 184, was thus ascertained to be Matonia 

 pectinata, R. Br. in Wall. PL Asiat. i. p. 16. t. 16, a name adopted 

 by Dr. Wallich in his Catalogue at the bottom of page 23, where he 

 directs it to be substituted for Prionopteris. In the course of this 

 examination, Mr. Moore further determined Sphceropteris Hooker iana, 

 Wall. Cat. No. 775, in corrig. p. 248, to be the same with Diacalpe 

 aspidioides, Blume ; a genus distinguished from Sphceropteris by its 

 sessile, not stipitate, sori, and which Mr. Moore refers to a section 

 (Woodsieae) of PolypodiecB, which connects that group with the Cya- 

 thece. Dr. Wallich compares it with Davallia stipellata. Wall. Cat. 

 No. 260, which it resembles in general appearance, but the fructi- 

 fication is altogether different. Davallia stipellata was identified 

 with Acrophorus nodosus, Presl, and doubtfully with Monachosorum
