P. subfalcatum — sub-fal-ca'-tum (somewhat sickle -shaped), Blame. 



This distinct, greenhouse species, of small dimensions, is a native of 

 Northern India, occurring at various elevations up to 8000ft. Its erect and 

 somewhat hairy fronds, 6in. to Din. long and fin. to lin. broad, are borne 

 on stalks less than lin. long, thinly clothed with soft, spreading hairs. 

 The close, spreading, sharply-toothed leaflets are of a soft, papery texture, 

 and slightly hairy on both sides. The small, 

 round spore masses are disposed in rows, one 

 to each tooth, half-way between the midrib and 

 the maroin. Fio\ 63 is reduced from Col.

P. (Niphobolus) subfurfuraceum — Mph- 



ob'-ol-us ; sub-fur-fur-a'-ce-um (somewhat 



scurfy), Hooker. 

 A strong-growing species, producing from a 

 short- creeping rhizome its entire fronds ljft. to 

 2ft. long, 4in. to 5in. broad, sharp-pointed at 

 their summit, gradually narrowed at their lower 

 part, of a leathery texture, naked on their upper 



surface, but somewhat rough with a woolly substance underneath. The spore 

 masses are disposed in one or two irregular rows of six to ten each. —
