TAYLOR: RAUNKIAER'S GROWTH-FORMS 487 
like a comprehensive view of the flora and vegetation of the island is 
excellent. 
Within the last few months it has been possible to separate the 
distribution maps of the species into two groups. The one which 
interests us just now is the smaller, consisting of the 400 commonest 
species. These make up the great bulk of the vegetation of the island, 
the other group of about 719 species being scattered and nothing like 
so common. 
When these four hundred species are sorted into the different 
growth-form categories of Raunkiaer and their percentages reckoned, 
we find them grouped as follows:!

The amount of deviation from the normal spectrum of Raunkiaer 
or from the growth-form percentages of the total flora of Long Island, 
or from the percentages of the local flora area? should show an inter- 
esting relation. The figures are as follows:

It will be seen from this table that the percentage of large and 
medium-sized trees, the herbs that root near the surface, and the 
annuals are somewhere near what the normal spectrum would lead 
one to expect. In fact the growth-form percentages of these 400 
commonest Long Island species are in remarkable agreement with the 
percentages of the total Long Island flora and of that whole region
