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 
Carvophvllaceae 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 published* at that time. A change of location and 
lines of work necessitated the discontinuance of this line of studv 
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 Silene conoidea L.f 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 Rockv 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.
