Sori indusiate, globose ; the receptacles medial on the venules. 

 Indusium reniform, affixed at the sinus. Veins (of pinnae) pin- 

 nate from a central costa, prominent ; venules simple, the lower 

 pair or more, sometimes all, angularly connivent-anastomosing, 

 producing from the angle an excurrent veinlet, which (in deeply 

 pinnatifid pinnse) is free, or (in less divided pinnae) joins the 

 next anastomosed angle. 



Fronds simple pinnatifid pinnate or pinnato-pinnatifid, herba- 

 ceous or sub-coriaceous. Spore-cases sometimes echinate. Ehi- 

 zome short, erectish, or slowly creeping. An extensive genus, 

 the analogue of Goniopteris among the Polypodiece. 



Tectaria. Anastomosed angles few, the lowest or lower venules onlr 



being connivently united.

X. molle, K. Br. N. venustum, Heward. 



N. caudiculatum, Pretl. \ N. unitum, Sory. 



Abacopterig. Anastomosed angles numerous, all or most of the venules 



being connivently united. 



Ex. : N. simplicifolium, J. Sm. \ N. acrostichoides, J. Sm.
