Den nøjere Undersøgelse af Ghromosom-Forholdene er ikke 

 foretaget, men det forekommer mig, at de fremdragne Forhold er 

 af Interesse derved, at de viser, at man hos en phylogenetisk set 

 saa ung Plante som Senecio finder Omstændigheder, der synes at 

 have Slægtskab med Polyspori. 



Summary. 



It is found that in Senecio vulgaris L. and in S. v. var. radiatus 

 four megaspores are formed, the three of which degenerate, the fourth 

 (the embryo-sac) developing in normal way, obtaining eight nuclei and 

 producing an embryo, as usually, after fertilization. The nucleus in the 

 three other megaspores always divide in two, so that the degenera- 

 ting megaspores are found to be bi- nucleate during a long time. 



It seems peculiar to find something having resemblance to polyspory 

 in such young genus as Senecio.
