POLYPODIACE-ffi. 31 



Hab. Chili : growing on trees, about six miles south of Valparaiso. 



Plant variable in the size, outline, and division of its fronds, as also 

 in the form of the sori, which we find either ovate or oblong ; the 

 latter form prevailing. 



This species, so far as we are aware, is the only one which properly 

 belongs to the genus Synammia as here characterized; although Presl 

 has removed to it the Qrammitis elmigata of Swartz; which Mr. J. 

 Smith places in the genus Phlebodium of R. Brown. In Synammia, 

 the sori may be said to be those of Grammitis, with a venation similar 

 to that of some species of Qoniophlebium of J. Smith. 



12. GONIOPHLEBIUM, Presl, J. Sm. 

 (Polypodii Spec, Auct. Marginaria, Presl.) 



The species of this genus varying very much in habit, Mr. J. 

 Smith has very judiciously divided them into four sections. 



§ 1. LOPHOLEPIS, J. Sm. 

 1. GONIOPHLEBIUM AURISETUM. 

 Polypodium aurisetum, Kaddi, Plant. Brasil. p. 12, t. 23, f. 1. 



Hab. Organ Mountains, Brazil : on trees. 



Raddi's figure of this slender creeping species, though faint in out- 

 line, represents very correctly the habit of the plant, and the form of 

 its diminutive fronds. 



2. GONIOPHLEBIUM VACCINIIFOLIUM. 



Polypodium vacciniifolium, Langsd. & Fisch. Ic. Fil. p. 8, t. 7; Willd. Spec. PL 5, 

 p. 145; Kaulf. Enum. Fil. p. 88; Raddi, Plant. Brasil. p. 13, t. 13, f. 2?
