NOTES ON THE EMBRYOLOGY OF THE CARYOPHYLLACEAE 



Mel. T. Cook. 



Some years ago the writer undertook a comparative study of 

 the morphology of several species belonging to the family 

 Caryophyllaceae and related families for the purpose of dem- 

 onstrating the constancy or variability of these internal char- 

 acters and thus reaching some conclusions as to their value in 

 phylogenetic studies. In connection with this work two brief 

 papers were pubHshed* at that time. A change of location and 

 lines of work necessitated the discontinuance of this line of study 

 and the writer has not had an opportunity to take it up again. 

 However, it has been thought desirable to offer these accumu- 

 lated notes. 



The Vaccaria vaccaria (L.) Britton was collected by Mr. H. H. 

 York near Greencastle, Indiana, in 1903. It is an European 

 species which has become rather widely distributed throughout 

 the country. 



The Siiene conoidea L.j was collected on the Agricultural 

 Experiment Station farm at Newark, Delaware. Only two 

 specimens were found and the seed of these were supposed to 

 have been introduced in Alfalfa from some of the Rocky Moun- 

 tain States. However, it proved to be a south European species 

 and it may have been introduced through an entirely different 

 source. It was collected primarily for class study, since the 

 embryos of members of this family are especially good for 

 class work.
