Of the above specimens, which were all introduced by seeds, the 
three marked with a * did not vegetate. Some species of Rdsa 
and Cratee‘gus, not included in the above list, have vegetated, 
but are not enumerated, as they have not yet flowered; and 
consequently have not yet been named or identified. 
To enable our readers to take a general view of the various 
details respecting introductions given in the preceding pages, we 
shall next endeavour to generalise them ; first, numerically; and, 
secondly, geographically. For the first object, we have had 
from our Hortus Britannicus an enumeration made of the num- 
ber of species introduced in each decade, from the beginning of 
the 16th century to the end of the year 1830. We do not give 
this enumeration as perfectly accurate; because many of the 
species in our catalogue, as in every other, are doubtful; but it 
is not of much consequence whether it be perfectly accurate or 
not; it is sufficiently so to show the ratio of the increase of the 
introductions, from the earliest periods of which we have any 
record of them, up to the present time.
