Our figure of the venation of the present East Indian F ern, 
in leones Filicum, is inaccurate, and it is a plant that deserves 
to be better illustrated ; the more so as our next plate will 
represent a Fern with very similar habit, and exactly similar 
venation, from the West Indies. Of the two Mr. J. Smith pro- 
poses to constitute a genus u Asplenidictyon .” Trusting, pro- 
babably, to the figure in the leones Filicum, Presl has placed 
Aspl. Finlay sonium in his group of Asplenium , “Venis venu- 
lis.que apice liberis.” In the “venulae apice arcu transverso 
conjunct9e,”our plant approaches Presl’s Thamnopteris section of 
Asplenium ; but, more than this, the veins anastomose, more or 
less, below the apices, as in Oxygonium , where however the 
involucres are diplazoid. It borders too upon Hemidictyon ; 
differing in wanting the marginal vein which unites the lateral 
veins in Asplenium (Hemidictyon) marginatum. Allantodia Bru- 
nonis , Wall., again, has the venation anastomosing, like our 
species under consideration, but the ultimate veinlets are all 
free and clavate within the margin. Such a structure in the 
venation affords beautiful sectional characters, but does not 
necessarily afford sound generic distinctions.
