E. tetrodohta F.v.M. Floral disc more or less prominent, forming a dark carnose covering over the 

 top of the conical ovary, almost up to the base of the style, and projecting in the thickish ridges over the 

 centre of the embryonic valves of the ovary, and thus forming three or more distinct ovarian nectaries. 

 Capsular disc forming a small dark carnose ridge over the centre of the valves as in the floral disc, and 

 considerably lower than the staminal ring, which remains conspicuous on the ripe capsule. (No figure 

 given of disc of E. tetrodonta at this place.)

E. Watsoniana F.v.M. 

 5a. (a) Calyx-tube. 



(b) Thin jagged membrane or inner lining of the operculum, which becomes detached from the lower 

 inner edge, as the operculum falls off. (Same as 1b (c), in E. pyriformis var. Kingsmilli.) 



5b. Operculum from the inside. Note the thick texture.

E. Oldfieldi F.v.M. Floral disc forming a short tubular raised disc above the base of the ovary 

 and top of the calyx and about 2 to 3 mm. from the staminal ring. Staminal ring slightly raised above 

 the top of the calyx, so that a shallow trough-like nectary is formed. The deeper hollow cavity around 

 the top of the ovary would also serve as a reservoir for nectar. Capsular disc thick, semiconical 

 (resembling the lower half of a cone), truncate, exceeding the calyx-rim by 4-5 mm. The morphosis of 

 the disc from the flowering to the fruiting stage in this species is similar to that of E. pyriformis and the 

 variety Kingsmilli. 



6a. Flower with stamens removed. 



(a) Calyx-rim. 



(b) Staminal ring.
