GONIOPTEEIS. 



This is a well-defined genus, 

 formed out of Polypodium by 

 Presl. The name alludes to 

 the lesser veins running in 

 angles (gonia), and pteris, a 

 Fern ; or, in simple English, 

 the Angular Fern. The species 

 of this genus are not numerous, 

 and grow only to a medium 

 size, never exceeding 3 feet, and 

 generally not more than 1 foot 

 in height. The most interesting 

 are 



GONIOPTERIS CRENATA (Scol- 



loped-edged), Fig. 28. A native 

 of the West Indies, and very 

 handsome. Fronds rather under 

 2 feet high, pinnate ; pinnso 

 crenate, downy, pale green. 

 Sori medial that is, between 

 the veins. 



Under the name of G. Ghies- 

 brechtii M. Linden introduced 

 a Fern which appears to be a 

 variety of that above mentioned; 

 it is more downy, and has but 

 little to recommend it. It was 

 named in honour of the botani- 

 cal collector who discovered it.
