lyichens are not abundant, Peltialii being found on old walls, 

 and two species of Cenomyre on decaying vegetables. As a 

 matter of fact mosses and lichens are but little known or 

 examined and the study of them might elucidate facts unknown 

 here at present. 



Class IV: Cryptoyamia. 



Natural Order Filices. 



The ferns and fern life of these islands are so fully and ably 

 described in a bulletin of the Torrey Botanical Club, by Mr. 

 B. D. Gilbert, that to give another description here would be 

 only invidious. Consequent!}' the naines and habitat are 

 simply given, with any special remarks called for. The princi- 

 pal fern localities are the marshes and the caves, and damp 

 walls or rocks. 



Adiantum Capillus Veneris — Walsingham district. Planted 

 out by Governor Lefroy. It is not a native or indigenous, but 

 may from its spread be now counted as a naturalized species. 



Adiantum bellum — A common fern, growing everywhere on 

 rock surfaces by the roadside and on garden walls. 



Adiantum bellum walsingense — A variety of the above but 

 much larger. Abundant near Walsingham. 



Pteris Longifolia — ^Jam. Uncertain whether it is a native or 

 naturalized. Crevices of walls and rocks round Hamilton. 



Pteris heterophylla — Open caves and cliffs of Walsingham. 

 It is known as the " parsley fern." Scarce. 



Pteris aquilina, var. caudata — Devonshire marsh. Very 

 luxuriant, growing from ten to twelve feet high. 



Woodwardia virginica — Pembroke marsh, and north side of 

 Devonshire marsh, plentiful in latter locality. 



Asplenium dentatum — Frequent on rocks at Walsingham. 



Asplenium Trichomanes — Common everywhere. 



Asplenium Myriophyllum— Rare, and liable to extinction.
