P. Griffithii— Grif-fith'-i-i (Griffith's), Eooler. 



A small-growing, stove species, native of Northern India, with broadly 

 spear-shaped fronds 6in. to Sin. long, borne on slender, erect stalks of the 

 same length and of a wiry nature. The upper lateral leaflets are simple and 

 not more than Jin. apart ; the lower ones are 2in. to Sin. apart and are 



divided to the midrib, their lowest leafits being fre- 

 quently divided again ; all are of a somewhat leathery 

 texture, naked on both surfaces, and the involucre 

 which covers the spore masses is narrow and of a 

 parchment-like texture. Fig. 76 is reduced from Col. 

 Beddome's " Ferns of British India," by the kind 

 permission of the author. — Hooker., Species Filicum,

P. (Litobrochia) Hsenkeana — Li-tob-roch'-i-a ; 

 Hsenk-e-a'-na (Ha3nke's), Presl. 

 A stove species, native of Guatemala, New Granada, 

 and Peru, with -fronds only once divided to the midrib, 

 of a leathery texture, and naked on both surfaces. The 

 spore masses do not reach quite to the extremity of the 

 leaflets. This species is of little decorative value. —

P. heterophylla — het-er-oph-yl'-la (having variable fronds), Linnceus. 



This stove species, native of Brazil and the West Indies, is of medium 

 size only. Its broadly-triangular fronds, 6in. to 12in. long, 3in. to 6in. broad, 

 and three times divided to the midrib, are borne on wiry, slender, naked stalks 

 of a peculiar straw-colour. With the exception of two or three of the 

 uppermost leaflets, all are compound, with leafits again deeply cleft, their 

 ultimate segments being egg-shaped, sharply and deeply toothed, wedge-shaped 

 and entire at the base, of a thin, papery texture, bright green and naked on
