 Papilionaceae. (University of Colorado Studies. Vol. I. 

 No. 3. April 1903. p. 239—243.) 



The writer notes the difference in shape and internal struc- 

 ture between the Cotyledons and foliage leaves of of a number 

 of Papilionaceae. The cotyledons are ^labrous, even when the 

 foliage leaves are hairy, and are amphistomatous where the 

 foliage leaves are hypostomatous. The flexuous margins so 

 often characteristic of the epidermal cells of the foliage leaves 

 are absent in the case of the cotyledons. The spongy paren- 

 chyma of the cotyledons is less cavernous than in the ordinary 

 vegetative leaCes, and glandulär cells, which are often present 

 in the latter do not occur in the former. E. C. Jeffrey.
