CLASSIFICATION: | 147 
class are included all those plants whose filaments ' 
are fewer in number than the segments or petals of 
the corolla. To the twelfth belong all the cruci- 
form plants; to the thirteenth, all the papiliona- 
ceous; and to the fourteenth, the ringent or la- 
biated flowers with four stamina. The last class 
contains all the compound flowers. The orders in 
this system are taken from all parts of the flower 
and of the fruit. 
Roven and WacHENDoRF have constructed si- 
milar systems, the first of which deserves the pre- 
ference. But all these systems are attended with 
difficulty, on account of the various parts of plants 
which we must have constantly in view, and the 
great number of subdivisions which thev neces- 
sarily require. :

Linnaeus, in his System, has fixed upon the 
stamina as the foundation of his divisions.
