PoLYPODIUM SUBFALCATUM. (BL) Caudex small, obliquely erect crinite rather than paleaceous, stipites short 3-8 3 
lines long patenti-pilose, fronds firm-membranaceous hairy on both sides, or sometimes sub-glabrous beneath, 6-8 inches long 1-1} inch 3 
broad, oblong-lanceolate subacuminate attenuated below deeply almost to the rachis pinnatifid, segments horizontally patent from a A 
rather broad and decurrent base, linear lanceolate acute strongly serrated or pinnatifido-serrate, or slightly sinuate only, (sub-entire), 
lower ones remote distinct smaller than the rest, costule slender flexuose, veins evident distant simple oblique soriferous at the apex, 
sori small globose. Hook. Sp. Fil. iv. p. 193; Bl. Fil. Jav. p. 186 ; P. filipendulifolium ;—Fée. Gen. Fil. p. 240 ;—Variety B سر‎ 
glabrum, fronds glabrous beneath except on the costa, segments slightly sinuate or sub-entire. 
The two varieties here figured have just been forwarded to me from Ceylon by Mr. Thwaites who refers them I think correctly 3 
to P. subfalcatum (Blume), the more hairy variety has already been figured in “the Ferns of Southern India,” Plate No. CLXVI, but - 1 
incorrectly named P. parvulum (which species has a creeping caudex). The fern figured at Plate LXXVI of this work as P. subfalcatum, 3 
has the veins soriferous in the middle, and is probably an undescribed species although the a accompanying the Plate refers 1 
to P. subfalcatum. | |
