ON SOME ODD BERRIES 



varieties from different regions, and have pro- 

 duced some interesting anomalies. One of these 

 was the result of hybridizing a native red species 

 known as Ribes sang nine um. By selection and 

 cultivation, varieties of this plant have been pro- 

 duced on my ground that bore flowers of brilliant 

 colors and the largest fruit, perhaps, ever seen on 

 a currant bush. 



Most of the crosses of this species were made 

 between a form collected on Vancouver Island, 

 British Columbia, and the forms native to the 

 regions about San Francisco. The Vancouver 

 forms had long racemes of light crimson flowers 

 and small bluish fruits. The coast form has 

 larger fruits with a more resinous odor, the ber- 

 ries varying in color from bluish to black. My 

 efforts with these species were mostly directed 

 toward increasing the size of the fruit. As just 

 stated, the results are quite noteworthy. 



Bui the experiments are still under way and 

 the ultimate possibilities of development are yet 

 to be revealed. 



My experiments in hybridizing the currant 

 have extended to all the species and varieties that 

 I could obtain. At times I have had five thousand 

 currant seedlings under observation. 



In addition to the European and American 

 species, I have worked extensively on varieties
