lata; but when pure it never has purpHsh or purple-dotted 

 capsules. The green-capsuled plants seem to be seedlings 

 with the recessive character in color of capsule. The black 

 seeds are nearly those of ['. cucullata, black being dominant 

 over buff— the color of the seeds of V. amnis. . (In my cul- 

 tures of this hybrid the recessive buff re-appears in some of 

 the offspring. See Science 25:940-944. June 14, 1907.) 



In No. 305 (but not in 306) the short auricles of V. affinis 

 appear with the green capsules of V. citciillata)."~Ezra
