 the average plant of English origin. 



The Oregon Male Hops. 



A comparison of the characters of the four hills of male hops obtained 

 from Oregon leads to the conclusion that they are all of the same 

 variety, and that tliis variety differs from the English male hops in 

 certain well-marked features. The differences drawn u]( in tabular 

 form will serve to emphasize this point. 



The leaf-glands of the Oregon 3 hop are generally more numerous 

 than in the English males, though among the latter occasionally a 

 plant is met with possessing leaves as glandular as in the former. 



The differences, particularly those concerned with the stipules 

 and the shape of the leaf, are so marked that it appears advisable to 

 consider the Oregon form to possess specific rank distinct from 

 H. lupulus L. ; this point will be found discussed elsewhere^. 



Type Characters. 



The observations recorded in the foregoing pages show tliat although 

 in the English male hops there are certain characters which, within 

 fairly narrow Umits, are constant for the individual plant, there is
