 underground, stipites subfasciculate a span to 1^ foot long 

 black-purple, fronds subcoriaceo-menibranaceous simple G-lO 

 inches long H-2 inches wide in the middle broad-lanceolate 

 or subelliptico-aeuminated entire narrow cuneato-attenuate 

 at the base, veins numerous approximate simple or forked 

 anastomosing only at the margin into 1-2 rarely more series 

 of oblong hexagonal areoles, sori narrow-linear on all the 

 straight veins but scarcely extending to the anastomosing 

 ones. (Tab. CCCII.) 



llab. Singapore, Wallich. Borneo, Sarawak and Labuan, Wallace, Thos. Lobb, 

 Motley. — Tbis is reacbly distinguished from G. aliamasfoUa by its longer and truly 

 lanceolate fronds with a tapering narrow cuneate base, and all my specimens are 

 very uniform in this respect. 



§ 6. Selliguea. — Primary veins often pinnated from a central costa, the rest 

 (or all) uniformly but often irregularly anastomosing, with or without free 

 veins. Fronds mostly simple and entire, rarely pinnatifid. — Tliis is among 

 Grammitidece, in regard to venation, what Phymatodes is among Polypodiete. —
