Sori indusiate, oblong-cjlindrieal ; the receptacles sub-lateral 

 anterior on the basal part of tlie veins. Indusium membranace- 

 ous, fornicate, at first involTiug the sorus, at length reflexed. 

 Veins simple, parallel at the base and there soriferous, becoming 

 forked and reticulated in elongated areoles towards the margin ; 

 the ultimate veinlets free, clavate, terminating within the margin. 

 Fronds pinnate, tender, herbaceous. Ehizome decumbent ? 

 The origiaal species of Allantodia are not distinct from the short 

 tumid-fruited species of Aspleniwm. In the present plant, also 

 referred to Allantodia by the author of the genus, (whose name 

 Dr. Wallich has happily associated with it), the veins are re- 

 ticulated, and the peculiar character of the sori^cyUndrical and 

 sausage-shaped — is much more manifest.

Sori linear oblong, obsoletely indusiate ; the receptacles lateral, 

 usually anterior i.e. in reference to the segment, (posterior in 

 the basal sori). Indusium "linear narrow plane, sometimes 

 obsolete,'' (SoolcJ: "thin, narrow," (Fee). Veins obscure, 

 forked from a central costa, parallel and soriferous below, anas- 

 tomosing irregularly near the margin, the basal anterior venule 

 (i.e., anterior in reference to the frond,) soriferous on its ante- 

 rior side. 



Fronds pinnatifid coriaceous, densely clothed beneath with 

 membranous imbricated scales. Ehizome short erect. — This 

 genus is anomalous. Its affinity is with the Aspleniece on account 

 of its lateral sori ; but the sori in the common species seem to
