An Improved Evening Primrose 



Mr. Burbank has worked extensively with the evening 



primrose. This one is a species from South America, which 



attains altogether unusual dimensions, some specimens suggesting a 



small handkerchief spread out on the foliage. Mr. Burbank's 



experiments with the evening primrose have convinced 



him that Professor DeVries' celebrated mutants of 



this tribe are in reality hybrid forms.
