Sori linear, running along the veins, in + 2 — 3 longitudinal rows on 

 each side of the costa, approximate or contiguous, united by transversal bars, 

 at length not rarely confluent, sometimes acrostichoid. Paraphyses? No in- 

 dusium. 



Rhizome oblique or erect. Fronds dimorphous, not articulate to the 

 rhizome, simple or irregularly incised or divided. Barren fronds sessile or 

 stalked, clustered, if sessile or subsessile then not rarely in a dense rosette; 

 venation as in Aspidium; main veins distinct; areolae irregular, with free 

 veinlets. Fertile fronds long-stalked, contracted. (*)

Rhizome erect or oblique, the scales dense, brown, often crisped, lanceo- 

 late or subulate, entire or variously fringed. Fronds dimorphous, simple or 

 irregularly divided. Barren fronds sessile or stalked, clustered or placed in a 



(') Diflers from Syngramma and Hemionitis by the aspidioid venation, the distinct 

 main veins and the areolae provided with included free veinlets. Its natural place is near 

 Lieptochilus, from which genus it is hardly distinguishable in the forms with confluent sori. 

 The sporangia are densely intermixed with paraphysiform corpuscles, probably the persistent 

 stalks of fallen sporangia.
