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

 Indmsivm. reniform, affixed at the sinus. Veim (of pinnse) pin- 

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

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

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

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

 next anastomosed angle. 



Pronds simple pinnatiSd pinnate or pinnato-pinnatifid, herba- 

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

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

 the analogue of Goniopteris among the FoT/tjpodiea. 



§ TectaHa. — Anastomosed angles few, the lowest or lower venules only 

 being connivently united.
