The relation of the capsules to the indusium requires fur- 

 ther examination. Do the capsules arise form an equilateral 

 thickening of the vein, or from a more or less lateral one. If 

 this is the case they would be Aspleniaceous, with a partial 

 indusium. 



In Mr. Edgeworth's herbary other instructive forms occur, 

 such as Nephrodis Aspidioids, having the lower sori those of 

 a Nephrodium, the upper, those of a Aspidium. 



There is in the same collection another species apparently of 

 Stenochlamys. 



Meniscuim. — Frondibus bipedalibus 1 pinnatis, stipilibus 

 supra sulcatis, velutinis pinnis suboppositis subsessilibus, li- 

 neari-oblongis acuminatis fere caudatis, crenatis, vena primaria 

 utrinque pubescente, venatio unita ; venae secondaries obliquae 

 intra marginem, arcuatim connectuntur, arcu venulas ultimas 

 brevissimas clavatas, intra marginem desinentes, emittit. Ter- 

 tiariee cum secondaria angulum sectum formant et medio in- 

 terstitu mutuo anastomosant. 



Harum par infimum arcuatur externe et vero Menisciforme, 

 reliquse fere sectae sunt. H33 tertiariae soriferae sunt, angulo 

 junctionis parum soriferarum, venula ultima oritur quae inter 

 spatium, et ejus medium circiter clavatim desinet. At hae 

 ultimae peripheram versus magis evolutae sunt, ita ut venula 

 infima Menisciformi omnino desit. Sori oblongis venulis trans- 

 versis tertiariis insidentes verno compositi, aspectu similes 

 omnino nudi.

The above description of the veins refers alone to the sori- 

 ferous frond, and this only when held up to the light, the 

 ultimate veins originating from the angles, are when the frond 

 is viewed as an opaque object, at least those towards the 

 margin evidently coalesce into the composite vein. In the 

 sterile frond the composite vein is complete from the greater
