GENERAL DIVISIONS OF JUSSIEU. 
The first section, Apetalous (wanting petals) is divided into 
three classes. 
1st, Comprehends all dicotyledonous plants destitute of a corol- 
la, which have the stamens epigynous ; as wild ginger.

which have the stamens perigynous ; as dock, &c. 
3d, Comprehends all dicotyledonous plants, destitute of corolla, 
which have the stamens hypogynous ; as plantain, &c. 
The second section monopetalous is divided into four classes. 
1st, Comprehends all dicotyledonous, monopetalous plants, 
which have the stamens hypogynous ; as milkweed, &c. 
2d, Differs from the first only in having the stamens perigynous ; 
as, the wintergreen, &c. 
3d, Differs from the two preceding, in having stamens epigynous , 
and anthers united ; as, lettuce, &c. 
4th, Differs from the third only in having the anthers separate ; 
as, the elder, &c. 
The third section, Pohypetalous , is divided into three classes. 
1st, Stamens epigynous: as, umbellate flowers. 
2d,' Stamens hypogynous ; as cruciform flowers. 
3d, Stamens perigynous ; as, the rose, &c. 
The fourth section anamalous , contains the 15th and last class 
of the method of Jussieu. 
This class contains the melon, hop, oak, &c. It corresponds to 
the classes Monoecia and Dioecia of Linnaeus. 
These fifteen classes are divided into 100 families or orders as 
they are sometimes termed ; but the word order , being appro- 
priated to the artificial system, that of family seems more prop- 
erly applied in this case.
