CROZET FLORA. 



From some specimens preserved by officers of the Mouongahela, when 

 that ship visited Possession Island, the largest of the Crozets, on its 

 way to Kerguelen, I have been enabled to identify the following-named 

 plants as common to both islands: — 



1. Pringlea antiscorbutica. — Growing much less luxuriantly than 

 on Kerguelen Island. 



2. ac^na affinis. 



3. azorella selago. 



4. Galium antarcticum. 



5. Leptinella plumosa. 

 (). lomaria alpina. 



7. A moss believed to be Andre^a marginata. 



8. Also "a small vine, with blue flowers, growing among seorise." 

 No specimens preserved.
