 Slrachey and Winterbottom ; Lachen and Sikkim, Hook. fil. and Thomson. 

 Bhotan, Griffith. — This has, I think, sufficiently marked characters to merit 

 rank as a species, and my specimens exhibit few variations. 



16. A. (Polystichum) triangidum, Svv. ; caudex short stout 

 erect or oblique clothed above with large intensely black 

 glossy brown-margined scales, stipites tufted from an inch 

 to a span long fusco-paleaceous, rachis straight or flexuose, 

 fronds coriaceous lanceolate gradually acuminate pinnated, 

 pinn£e often distant rhombeo-ovate subfalcate lower ones 

 triangular, the apex and distinct auricle generally on each 

 side at the base spinose, the margins thickened sinuato-den- 

 tate, sori in 2 rows and more or less extending to the auri- 

 cles.— -Si^. Syn. Fil. p. 14 [excl. syn. Schk.). Willd. Sp. PL v.

 de Cuba, Linden, n. 2193 {Fe'e), C. Wright, PL Cub. n. 829.— I must refer to my 

 figure of this species, in ' Filices Exotica;,' and to ray description and remarks, for 

 my reasons for uniting Fee's Polyst. cyjjhochlamys and his P. ilicifolium with it. I 

 have seen no authentic specimen of the true traj)e::ioides, Sw., but suspect it to 

 be the same as this. 



17. A. (Polystichum) viviparum, Fee; ''fronds below 

 bipinnate, above pinnate virgate radicanti-viviparous, rachis 

 stout channelled rufescent, scales lanceolate acuminate black
