The Natural Orders of Jussieu are 100. They are as yet, ob- 
scure and undefined in many particulars. 
The plants which have but one cotyledon, are divided into 
three classes ; they include the grasses , the palms , liliaceous 
plants, &c. 
The plants with two cotyledons are divided into 1 1 classes ; 
these include all remaining plants, except some genera which 
appear so ambiguous in their character, as to render it doubtful 
where to give them a place in the Natural Orders. 
In the three methods of classification which we have now 
examined, the most important characters of the plant have been 
presented, under circumstances, calculated to give you more 
clear ideas of them than could have been obtained from a on- 
sideration of any one method alone. 
Tournefort makes you acquainted with the different appear- 
ances of the corolla. 
Linnaeus, of the stamens and pistils. 
Jussieu, of the cotyledons and insertions. 
The method of Tournefort cannot be relied on because the 
forms of corollas vary into each other ; that of Jussieu, consider- 
The three methods of classification considered, present the most important 
characters of the plants under different points of view — Comparison of these 
methods —
