192 CHARACTERS OF TRIBES AND GENERA. 
Filicum," they are very widely spread in the tropics ani 
extratropical regions of both hemispheres, extending to 
New Zealand in the south and Japan in the north.

(Bedd. F. Brit. Ind., pl. 220); G. urophylla, Wall.; G. 
sub-pectinata, Wall. (G. crenato-dentata, Fée); G. lineata,

. Oss.—It is difficult to reconcile the humble G. reptans 
and its allies as belonging to the same genus with the 
splendid G. Sandvicense and G. costata, the first being a 
native of the Sandwich Islands, having an erect arborescent 
cordex, 1} feet high, bearing a crown of long stipate fronds 
5 feet in length, which, with G. costata of India and G. 
. pennigera of New Zealand, which also has an arborescent 
caudex, seems to have some claim to rank as a distinct 
genus. 
In Beddome’s “Ferns of British India," G. costata and 
G. lineata are said to be indusiate, and consequently belong 
to Nephrodium.
