92 CHARACTERS OF TRIBES AND GENERA.

G. fraxinifolium ( Jacq.), (vv.), G. distans (JRadd.\ (vv.), 

 G. menisciifolium (Lang et Fisch."), (v v.), G.dissimile (Z/mn.),

 ineequale (/. Sm.), (v v.), (Phlebodium, Moore}, G. neriifolium 

 (SM.), (vv.), G. cordata (Kze.). 



The whole of the above are natives of West Indies and 

 America, extending to California and Chili ; the greater 

 number being found in the tropics. 



No representative of the genus is recorded from Africa 

 except the aberrant species, G. ensiforme (Polypodium 

 ensiforme, Thunb.), a native of South Africa, which, although 

 agreeing in venation, nevertheless differs essentially in the 

 texture of the frond, which is thick and coriaceous, with 

 immersed obscure veins, and large uniserial sori. In these 

 respects it has the appearance of a Pleopeltis or Phymatodes, 

 but is entirely destitute of scales. 



The genus Synamia of Presl is founded on P. trilola of 

 Cavanilles, and with it is associated Gratnmitis elongata of 

 Swartz. The first is recorded above, and differs only from 

 true Gonioplilebium in having oblong sori ; the other, which 

 has also oblong sori, but differs essentially in habit, as also 

 in venation, I place under Pleopeltis. 



In G. incequale the costal areoles are void that is, desti- 

 tute of a free venule, in that respect agreeing with the 

 allied genus Phlebodium.
