Grammitis (Calymmodon) clavifer, Hook. 



Caudice crassiusculo repente, frondibus vix stipitatis digitali- 

 bus firmis rigidis dense caespitosis lineari-lanceolatis pin- 

 natis, pinnis remotis patentibus apice piliferis, sterilibus 

 angustissime linearibus, fertilibus spathulatis acutis margine 

 superiore reflexo, vena (seu costa) solitaria infra apicem 

 terniinante clavata sorifera, soris solitariis oblongis apicem 

 dilatatum pinnae occupantibus, rachi angusta lineari-suba- 

 lata patentim villosa. 



Hab. Kina Ballu, Borneo, Hugh Low,junr. Esq. 



As far as I can judge from Fee's figure and description of 

 his Plectopteris gracilis, it is identical with the Calymmodon 

 cucullata of Presl, and the Grammitis cucullata of Blume, and 

 of J. Smith ; and no less so with Grammitis denticulata of 

 Blume, ( Polypodium cucullatum of Nees and Blume in Nov. 

 Act. Acad. IS! at. Cur., and P. denticulatum of Bl. Syn. Fil. 

 Jav.) If this be correct, this genus (or section of Polypodium 

 or Grammitis, according to the views of Botanists,) is reduced 

 to a solitary species ; but to this I have added the very 

 elegant Fern now before us, which I prefer retaining in 

 Grammitis. It is readily distinguished by the more slender 

 habit, and deeply and narrowly divided frond, rather pinnate 

 (with the rachis narrow-winged) than pinnatifid ; the sterile 

 pinnae are narrow linear almost acicular, while the fertile ones 

 are truly spathulate or claviform, and mostly confined to the 

 middle or upper part of the frond. 



I may observe that the Grammitis cucullata, of an un- 

 usually large size, is also found on Kina Ballu, by Mr. Hugh 

 Low, junr.
