EPIGYNEiE. 



In this group or series, the perianth is in whorls ; 

 and, except in the Dioscoraceae, it is coloured. The 

 ovary is inferior, syncarpous, and three-celled. The 

 seeds are large and contain endosperm. 



Included in this group are the Iris group, the 

 Snowdrop group, and the Black Bryony Group. 



In the first two the flowers are complete ; in the 

 Black Bryony group unisexual. The perianth is six- 

 partite, and petaloid in the Iris and Snowdrop groups. 

 In the Iris group there are three stamens, which open 

 outwards ; in the Snowdrop group and Black Bryony 

 group there are six stamens, which open inwards. 

 The ovary is three-celled. In the Iris and Snowdrop 

 groups the fruit is a three-valved capsule ; in the 

 Black Bryony it is a berry. 



All are herbaceous plants, the Black Bryony being 

 a climbing plant. The veins in the latter are net- 

 veined. 



The Yellow Flag was described in the Introductory 

 Volume.
