rich in protoplasmic contents, and this led Jeffrey to sus- 

 pect that a reinvestigation of Funkia with the aid of modern 

 technique would reveal a similar condition. The examination, 

 however, confirmed Strasburger's account, so that while the 

 general appearance of sections is much the same in the two 

 cases (cf. Figs. 99 and 100), it is established that in Funkia 

 the embryos come from the nucellus, while in Erythronium they 

 come from the fertilized egg. In Erythronium albidum Schaff-

pensor, but it was associated with only one embryo. In Tulipa 



Gesneriana Ernst 69 also observed the phenomenon of a massive 



suspensor associated with one to six embryos, only one of which 



usually persists. In these cases the Lilium type of embryogeny 



is obscured by the early and rapid growth of the suspensor 



region of the proembryo. the embryonal cell appearing hardly 



more than one of the cells of its free surface. In these cases
