Hab. Kina Ballu, Borneo, Hugh Low^junr, Esq, 
As far as I can judge from Fee’s figure and description of 
bis 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 Kov. 
Act. Acad. Kat. 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.
