E. alpina Lindl. 



Floral disc not raised, but forming a broad dark, carnose, pitted band or ring around the ovary. 

 This, no doubt, is referable to the term " discal space " of Mueller, and therefore it is interesting to trace 

 its development from a coloured band or ring to a broad domed disc on the capsule. 



Capsular disc thick, domed, completely absorbing the staminal ring, exceeding the calyx-rim by 

 3-5 mm. 



The following figure is magnified about twice natural size.

7?. robusla Sm. 

 Floral disc forming a dark carnose lining to the calyx-tube flush with the rim of the staminal ring, 

 and slightly extending over the outer edge of the ovary. 



Staminal ring slightly raised above the edge of the calyx-rim. 



Capsular disc, a little thicker than the floral disc, convex on the inner face, the edge flush with the 

 staminal ring, which still retains its elevated position over the calyx-rim on the ripe capsule, and referred 

 to by Mueller as the " Annual margin of the disc." It is common on species with this class of capsule, 

 and also on the capsule of species whose valves are enclosed. 



The following figures are magnified about three times. 

 10a. 



Flower enlarged with nearly all the stamens removed. Seen from the top. The three dark 

 shaded portions surrounding the style are the nectaries.
