From these tables it will be seen that of 104 species of 



plants, 51 contained albumen stored up, in one part or another, 

 active while 53 did not contain it at all. 



The plants examined belonged to 52 families. 



The active albumen was found in 29 families. 



It is of physiological interest to see how the active albumen 

 often accumulates in the flowers and that in such cases it may 

 be absent in the green leaves or decrease in those parts that 

 are nearest to the flower (compare the above observations with 

 Punka Gvanatum, Nandina domcstica, Evonymus japonica and 

 Fagopyrum escidentum). In Gramineae I found active albumen 

 thus far only in the epidermis of seeds and only in a certain 

 period of development.
