and the Liliaceze occupy the head of an alliance of which Junca- 
cee may be considered the center. This alliance will include 
Amaryllidez and Iridez, and connect through Flagellariee with 
the Palme, which itself stands at the head of the Aroidal alli- 
ance, with Lemnacez in the lowest rank. On the other hand, 
Gramineæ and the other glumaceous plants are indirectly con- 
nected with Juncacez, and are at the head of the glumaceous
