ON THE PLACENTA OF PJUMI'LACE.dE. 



By G. S. Boulger, F.L.S. 



In reading Dr. Masters' interesting paper on the Morphology of 

 the Primulacecc (Linn. Trans., series IL, vol. i., part 5), I was 

 much struck with the following passage on Pr'unula (p. 288) : — 

 *' Within the rudimentary pistil .... the receptacle changes its 

 former fiat or dej)ressed condition for a convex or dome-shaped 

 appearance ; the middle portion of this dome becomes covered with 

 ovules from above duicmcards ; the upper portion elongates into a 

 naked cone ; and the lower portion forms a stipes, which is 

 apparently quite free from the walls of the pistil."
