Moist banks in Jersey, frequently in company with Marchantia, 

 discovered there by a lady, according to Mr. Newman. In March, 

 1854, we received specimens from Mr. Piquet, of St. Helier's, who 

 has detected several stations in the same island, — We should be 

 disposed to consider it one of the most widely diffused Ferns over 

 the globe, were it not that there is no notice of it in Ledebour's Flora 

 of the vast Empire of Russia, and none in Koch's Flora Germanica. 

 1 It is wanting also in the United States, though we have received it 



^P^(^i' j from Mexico; and common as it is about what may be termed the 



basin of the Mediterranean, it is much more universally diffused in 



the southern hemisphere. In the Channel Islands it has probably 



.) I reached its northern limits. Even in France, Britanny and Provence 



are the only localities recorded in Wood's Tourist's Flora, the 

 former of which countries brings it very near to us. Our Herbarium 

 ' ™ ^ possesses snecimens from the extreme north and extreme south of 



"^"^^ Africa, Abyssinia; from the East Indies, Himalaya and the Niel- 



]eitkr j gherries ; from Australia, Eastern, Southern and Western ; from 



New Zealand and Van Diemen's Land. Mr. Piquet remarks that 



the plant is truly annual, the root and fronds dying away entirely In 

 May, and springing again from seed in the Autumn. Height of the 

 plant from 2 to 4, or rarely 6 inches.
