Forma typica: Pinnae broadly ovate or triangular-ovate; macrospores 

 brownish, albo-verruculose ; microspores more or less prickly. Nicobares 

 to the Moluccas, Formosa and South China. 



Forma punctata: Pinnae elongate-oblong or lanceolate. Cuming's 

 No. 1995 has the macrospores pale-brown, finely verruculose, the micro- 

 spores yellowish, with densely crowded clavate or stipitate-capitate pro- 

 jections. - - Jagor's No. 905 (var. angustiramosa, Hieron., MS.), which 

 would be better treated as forma angustiramosa, has the macrospores 

 pale-yellow, finely verruculose, the projections punctiform or shortly rugi- 

 form, the microspores yellowish-white, with the projections tuberculiform 

 or clavate. Mindoro.
