20 
less than 30 feet. Of these the British Flora included nearly 40 
species, but several were only doubtful natives; but the intro- 
duced species were so frequent that he should be obliged to 
make some reference to them. He, therefore, shewed photo- 
graphs of the Lime tree, which many authorities asserted was 
introduced into Britain during the Roman occupation, but which 
was now so common an object in our parks, promenades, and 
plantations. He referred to it as being the name of the great 
botanist, Charles Lind, better known in its latinised form as 
Linneus, and said how excellent a tree it was for planting in 
towns ; the odour so well known was curious from the fact that 
it waS more pronounced at a little distance from the tree, when 
one got closer it was less agreeable and less powerful. Specimens 
of the Limes by the Thames, at Windsor, and at Dorchester were 
shewn. In passing, the Lecturer remarked that two species of 
Lime, the small and the large-leaved Lime, were supposed to be 
native trees. 
The Oriental Plane was next described, and some botanists 
believed it was also introduced by the Romans, others that it was 
not brought to Britain until the 15th or 16th Century. This tree 
is also well adapted for planting in towns, since it bears the 
smoke better than most species. It is a native of the East, and 
was introduced into Sicily about 600 years before Christ, and was 
a favourite tree of both the Greeks and Romans. The photo- 
graph exhibited was from the large tree at Rycote, in Oxford- 
shire, where Elizabeth was kept for two years in practical 
imprisonment. The peculiar undulating growth of the branches 
was explained. 
The Sycamore was then described as probably an introduced 
tree, but the date of its introduction was lost in remote antiquity. 
The tree was frequently planted about castles and farmhouses to 
give shelter, and in Scotland they received the name of doul, or 
grief tree, from the custom which once obtained of hanging a 
refractory vassal or captured foe upon them. Fine photographs 
of some trees at Inverary and Inverlochy Castles were shewn, as 
also one at Burford, in Oxfordshire. 
Brief allusion was made to the native dcery—or Maple— 
which is such a plentiful shrub in the hedgerows in limestone 
districts, and which has the same character as its American 
relations, that is in showing such gorgeous colours in autumn. It 
was mentioned that there were trees 40 feet high in Oxfordshire. 
The wood was greatly prized, and the celebrated Maser bowls 
were made of it which now fetched such extremely high prices. 
The Horse Chestnut was next mentioned. This tree was 
probably introduced in the time of Queen Elizabeth, as Gerard in 
1597 alluded to it as a rare foreign tree. The flower and the 
manner of fertilization was described, and photographs of the 
avenue at Bushey Park, and of a tree at Dorchester, were shewn.
