This singular and very beautiful Fern is, we believe, entirely confmed to New Zealand, where it 

 climbs over the trunks of trees. We have received it from Mr. Menzies ; but our finest specimens 

 were recently sent to us by Mr. Fraser, the colonial botanist in New South Wales. 



The substance of the frond is rather thick, and it is pellucid, and of that nature which would lead 

 to the suspicion of its having, in a frcsh state, been succulent. In drying, therefore, the specimens 

 may have shrunk considerably, especially at the margins ; and to this circumstance^ perhaps, may 

 be attributed the exserted state of the capsules.
