A very distinct and well-marked species ; its nearest ally probably is 



A. gigantea, Wall. — Caudex 4-8 feet high. Fronds 8-9 feet long. 



Stipes and main rachises dark-purple, glossy, rough with small raised 



points, not muricated. Pinnules large, from 4-5 inches long, 5 lines 

 broad, tapering much at the point, and there serrated, the margins ob- 

 scurely sinuato-dentate, the base truncated, not at all contracted. The 

 lateral veins are in fascicles, pinnated, the veinlets usually free, but 

 sometimes the lowest pair or more, meet the veinlets of the adjacent 

 fascicle. Sori rather small, globose, scattered. — It would probably be 

 a Gymnosphcera of Blume, and may possibly be his G. glabra, " fronde 

 pinnata, pinnulis lanceolatis apice argute serratis basi truncatis leviter 

 pinnatifidis glabris, laciniis rotundato-obtusis crenulatis," Ik. Fil. Jav.
