appearance of being truly wild. In Europe it is reported from 

 the Scandinavian peninsula, excluding Norwegian Lapland; also 

 from Russia (south and middle) ; Italy, from Home to the Alps; 

 north of Germany, Holland, Belgium, south of France, Austria, 

 Hungary, etc. De Candolle regards this plant as an introduction 

 from Java, the Moluccas and Malabar. Query, — Has it been 

 observed anywhere between Malabar, its most western native lo- 

 cality, and Hungary, its nearest adopted home in Europe ? Is it 

 a denizen of Asia Minor, or of Greece, or Turkey ? Is the Flora 

 of the Euphrates and its tributaries well known ? Have the stream- 

 lets and valleys of Armenia been well explored ? What may be 

 the botanical productions of the countries whence the human 

 race after the Flood departed to colonize the earth after its sub- 

 mersion in the waters of the great deluge. 



Mr. Moore claims Narcissus biflorus as truly indigenous in 

 Ireland. This is one of the doubtful species which Professor De 

 Candolle conjectures to have been introduced between the Roman 

 dominion in Britain and the discovery of America, or in round 

 numbers, 1,500 years : a sufficient period for the naturalization of 

 such a plant as Nar'cissus, which is very hardy and very durable. 

 Professor De Candolle states that it is indigenous in Italy and in 

 the south of France. Mr. Moore considers it to be a plant of 

 western Europe, and he is probably right. It does not appear 

 in Europe further east than the Tyrol and Italy. 



Senebiera didyma is one of the ten species which Britain, ac- 

 cording to De Candolle's theory, has received from America. 

 This plant is far more plentiful in the south-west than in the 

 south-east of England. This is also a plant of Spain and the 

 south of France. Probably Gothland, in the Baltic, is its most 

 eastern range in Europe. 



Again, Mr. Moore considers Mercurialis annuus and Geranium 

 pyrenaicum as both truly wild in Ireland. In the '' Geographic 

 Botaniqne ' they are in the list of thirty-seven European species 

 supposed to be naturalized in Great Britain. The annual Mercury 

 is very plentiful in the vale of the Thames, and if it be a native 

 of Ireland, where it is said to be very local, it may surely be 

 admitted to be a native of Britain. Its European range is, from 

 north to south, from Norway to Spain ; and from east to west, 

 from Turkey to Portugal. Geranium pyrenaicum is not restricted 

 to the vale of the Thames ; it is found near the top of Arthur's
