Placenta. 



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

 adnate or oblong and peltate axile placenta." (B.F1. iii, 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. pyriformis. 



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. Preissia,na. 

 Comparatively shorts — 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. erythrocorys, 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 (corynoealyx).
