Hab. North of India, frequent ; Nepal, Wallich ; Sikkim, Khasya, Assam, and 

 Bhotan, Griffith, Hook. fil. and Thomson. — Mettenius remarks, " Species fortasse 

 ad PherjopteriiUm aniandanda ;" but unmistakable involucres are seen on our 

 specimens. The S. American specimens noticed l)y Mr. Moore, in my herbarium, 

 from Ecuador {Jameson), I am satisfied, possess no involucre ; nevertheless they 

 have the partially anastomosing venation of our present plant, and the fronds 

 equally vary from pinnate to bipinnate, the latter form approaches some states 

 of Aspid. pla/)/phi/lhcm, \Yi\ld., Pheffopieris, Metten. All have a true polystichoid 

 habit. 



49. A. (Cyrtomium) falcatum, Sw. ; caudex short stout 

 erect, stipites tufted a span to a foot long very paleaceous 

 with large ovate setoso-acuminate membranaceous glossy

 oblongo-lanceolate pinnated, pinnpc ovate acuminate more or 

 less falcate petiolate repand at the margins which are some- 

 times serrated, inferior base cuneate superior produced 

 rounded subtruncate, veins variously and irregularly anasto- 

 mosing, costal areoles the largest generally including one free 

 vein (those nearer the margin with two or three veinlets) 

 clubbed at the apex and bearing a sorus on the back, involucres 

 orljicular peltate membranaceous firm with a central brown
