After having derived from the corolla the distinctions of clas- 
ses, Tournefort subdivided them into orders, or as he called 
them, sections. These orders were founded upon the observa- 
tion of the pistil, calyx, fruit, &c. 
The first step in this classification was wrong. The distinc- 
tion between a small tree and shrub, cannot be accurately de- 
fined ; there are many plants which we should doubt whether 
to class among large shrubs or small trees. Two circumstances 
were relied on as a foundation for this distinction ; viz, that 
shrubs do not form buds for the future year ; and secondly, 
the size of the plant. With respect to the formation of buds, 
the distinction is not found to be invariable, as some shrubs do 
form buds, and some trees do not. With respect to size, the 
variation, even in the same species, is such, in different soils 
and situations, that it cannot be admitted as a mark of distinc- 
tion.
