Alliance 2. Liliales. Hexapetaloideous plants, with an em- 

 bryo in the axis of the albumen. 



Petals rolled inwards after

 tinct. 



Flowers irregular, with ap-

Alliance 3. Commelynales. Tripetaloideous plants, with the

Alliance 4. Alismales. Tripetaloideous plants, with the car- 

 pels more or less distinct. 



Placentae spread over the 249. Butomacese . Acrid, 

 dissepiments. 



Placentas occupying the 250. Alismaceae . Acrid, 

 margin only of the dis-

Alliance 5. Juncales. Flowers somewhat glumaceous.

two-leaved calyx. 



Here we have a marked transition to Exogens on the part of Alisma, which is hardly 

 distinguishable from Ranunculaceae, except by its embryo. Liliaceae connect the group 

 with GynandrosEe through Apostasiaccne, Juncaceae with Glumosae through Restiaceae.
