1. LlTOBROCHIA GRANDIFOLIA, J. Sftl. 



LitobrocMa grandifolia, J. Sni. in Hook. Jour. Bot. 4, p. 163. 



Pteris grandifolia, Linn, ex Willd. Spec. PI. 5, p. 369 ; Agardh. G-en. Pterid. p. 7. 



Hab. Vicinity of Kio Janeiro and the Organ Mountains, Brazil. 



Whole plant usually from 3 to 5 feet high. Fronds smooth, erect, 

 oblong, and simply pinnate ; the pinna© subpetiolate, elongated lan- 

 ceolate and oblique at the base, with a perfect reticulated venation. 

 Stipes smooth, sulcate, and of a dull chestnut-brown colour. 



Presl appears to have committed an error in representing the Pteris 

 grandifolia of Linnaeus, in his Tentamen PteridographiaB, t. 5, f. 16, 

 as having a simply forked venation. 



2. LlTOBROCHIA DENTICULATA, Presl. 



LitobrocMa denticulata, Presl, Tent. Pterid. p. 149, t. b, f. 20. 

 Pteris dentictdata, Sw. Syn. Fil. p. 97; Willd. Spec. PI. 5, p. 372; Kaulf. Enum. 

 Fil. p. 187 ; Hook. & Grev. Ic. Fil. t. 28 ; Agardh. Gen. Pterid. p. 56. 



Hab. Organ Mountains and vicinity of Rio Janeiro, Brazil. 



This is a very variable plant, the most common form of which is 

 represented in Hooker and Greville's Icones Filicum ; and we are 

 inclined to think, that the Pteris serrata of the Flora Fluminensis, t. 

 82, and Pteris palrnata, t. 87, of the same work, are nothing more 

 than varieties of it.
