Conical in the centre and tapering into the style — E. goniocalyx. 



More or less conical in the centre, tapering into the style — E. dealbata.

Not much shorter than the calyx, conical in the centre — E. resinifera. 



Conical in the centre, with as many raised lines as cells — E. platypus. 



Convex or conical in the centre — E. siderophloia. 



Conical or convex in the centre — E. concolor. 



Very convex, or conical at the top — E. occidentalis.

Nearly as long as the calyx-tube and convex or corneal in the centre — E. tereti- 



cornis.

Placenta. 



" Ovary . . . . with numerous ovules in each cell, in 2 to 4 rows, on an 

 adnate or oblong and peltate axile placenta." (B.F1. hi, 185.) I can find no references 

 to the Placenta under species. 



'" . . . . with a thick central somewhat columnar or rarely pyramidal axis." 

 (Mueller in " Eucalyptographia".) 



When we come to individual species we find that Mueller speaks of the 

 Placental Column in six cases and Placental Axis in the remaining ten. In a few 

 instances he describes the shape of the axis, but, as a rule, he contents himself with a 

 statement as to their relative length and breadth, thus — 



Pyramidal-semiovate — E. piriformis. 



At last semiovate pyramidal, the cavity of the cells penetrating beneath the 



placentas — E. macrocarpa. 

 Wide — E. megacarpa. 



Conical or oval-cylindrical, almost twice as long as broad — E. Preissiana. 

 Comparatively short — E. sepulcralis. 

 Nearly as broad as long — E. pachyphylla. 

 Not twice as long as broad — E. alba. 

 About twice as long as broad — E. cordata, E. erythroeorys. E. hcemastoma, 



E. Raveretiana. 

 Hardly twice as long as broad — E. melliodora. 

 At least twice as long as broad — E. odorata, E. resinifera. 

 More than twice as long as broad — E. microcorys. 

 About three times as long as wide — E. cladocalyx (corynocalyx).
