Sori non-indusiate, consisting of few sporadic superficial 

 spore-cases occurring here and there on tlie veins in narrow 

 linear or small short groups ; the receptacles partially, though 

 Tery slightly, reticulated. Veins uniformly Tetieulated &om a 

 costa, forming elongated auh-hexagonal areoles. 



Fronds membranaceous, simple, articulated. Khizome creep- 

 ing.-r— Distinguished by its sporadic fructifications. It forms a 

 connecting link between Antrophyum and the Acrostiehea.

Sori non-indusiate, usually immersed, sometimes superficial, 

 narrow-linear, occupying the anastomosed reins which form the 

 sides of the areoles, mostly united; the receptacles therefore 

 partially, though generally, reticulated. Vein& uniformly reticu • 

 lated, from a costa or ecostate, forming elongated sub-hexagonal 

 areoles. 



Fronds simple, coriaceous or membranaceous. Sori continu- 

 ously or interruptedly reticulated. Ehizome tufted erect. — 

 Distinguished technically from Hemionitis only by the partial 

 though frequent reticulation of the sori. The habit and aspect 

 are, however, quite dissimilar.
