meadows, hayfields, farms, gardens, and well-wooded glens of Oak 
and other mixed foliage. The altitudes above the sea range from 
1200 to 2704 feet. The term highland applies to it, but, as many 
plants seem to grow in peculiar situations even in this area, special 
localities are in some cases also recorded. 
In these zones very different conditions are to be found suitable 
to the growth of plants, according to the exposed or sheltered 
state of the locality ; many exotic plants now growing in the 
Island have sought out the spot most suited to them, and flourish 
there, while they refuse to grow at some place perhaps only a few 
yards removed. Where no reference letter is used, it will be under- 
stood that the plant grows on the same interior central land as 
those denoted by the sign H. L. or high land. 
In denoting the altitude above the sea at which a plant grows in 
the Island, a number or decimal part of a number is employed, which 
it will be necessary in each case to multiply by 500, the result giving 
the altitude in feet ; this plan has been adopted for the purpose of 
lessening the number of figures that would otherwise have to be 
printed in denoting high altitudes. 
Wherever a local name could be found it has been added, and in. 
its absence some brief description of the plant given, by which in 
a general way it could be readily locally identified. 
There are some plants mentioned by Dr. Roxburgh, as seen in 
the Island in the year 1813, which have not been met with recently. 
It seems probable that they were at that time new introductions, 
and have not succeeded, but since died out ; they are, however, 
repeated in the present catalogue, because single specimens of them 
may possibly still lurk hidden in the wooded parts, and even if they 
do not it will continue a record of the effort made for their intro- 
duction. 
The following is an explanation of the signs and abbreviations 
which have been adopted in the catalogue : — 
Alt denotes altitude or elevation above the sea 
level. 
JJt „ height which a species attains. 
C „ near the sea coast. 
M „ midway between the coast and 
mountain.
