ANATOMY OF COTYLEDONS. 
Last year the writer published a short article’ describing some 
observations on the anatomy of cotyledons with a comparison of 
cotyledons and foliage leaves in the Papilionaceae. In that paper it 
was stated that the study would be continued to other plant families. 
This has been done in the case of representative species of the Cruci- 
ferae and Ranunculaceae by two graduate students, Miss Neata Clark 
and Miss Martha Phelps. A further investigation will be made in 
these same families and with other families. 
In the Ranunculaceae and Cruciferae studied there is not as great 
a difference in structure between cotyledons and leaves as was seen in 
the Papilionaceae. Thus the form of the epidermal cells is frequently 
the same in the two structures. There are, however, some differences 
in the arrangement and number of stomata, these being sometimes 
absent from one surface of the leaf, but present on both surfaces of 
the cotyledon. The trichome structures are frequently absent from 
the cotyledon when present on the leaf, and sometimes when present 
on the cotyledon they are of special form.
