EXOTIC PLANTS ABOUT LONDON IN 1865. 149 
An advantage attending the unchecked growth of these plants is 
found in the easier determination of their names. In the stunted 
specimens alone obtainable at Wandsworth this was often difficult, and 
I have a suspicion that some names in Mr. Irvine’s list may refer to 
allied species given in mine. 
I have here recorded no plants of whose nomenclature I am not 
satisfied. I do not doubt that four times the number were seen, 
but a few certain facts are preferable to a number of doubtful ob- 
servations. Had I thought at the time of publishing a list, I would 
have collected more and better specimens ; but, if the coming summer 
be favourable, no doubt a plentiful crop of novelties will be produced. 
The species are mostly Mediterranean; there are several from Cen- 
tral Europe, from Istria aud the country round Trieste, and a few spe- 
cies are Egyptian or Syrian. There are also two or three cereals of 
Europe. Some are likely enough to become cornfield weeds in this 
country, of the class represented by Agrostemma, Silene anglica,the Papa- 
vers, and Chrysanthemum segetum, and some have long been known as 
naturalized plants. Those marked W. are included in the Wandsworth 
published lists.
