The flower has six perianth leaves (II., IV.), slightly 

 coherent at the base with the six stamens adherent to 

 them ; the ovary is, as usual, three- celled (III.), while 

 the fruit is a berry (V.) ; and the seed (VI.) with much 

 endosperm around the embryo (VII.). If the diagram 

 (IV.) be compared with that of Hypox'is, it will be

 feature between the orders Amaryllidece and Liliacece, 

 is the inferior ovary of the former and the superior one 

 of the latter.
