30 Schively — Recent Observations on 



particularly good, I did not attach much importance to 

 this fact. 



During the summer of 1S98, I raised in the University 

 greenhouses, plants from seeds of undoubted A. vionoica (pur- 

 ple flower), from A. Pitcheri which had been sent me from 

 Iowa, and also plants of the white-flowered type. These were 

 grown in the same kind of soil, and under precisely the same 

 conditions of temperature, moisture, etc. Unfortunately, the 

 plants did not flower as abundantly as I should have liked, 

 but the same results in regard to number of seeds in the vari- 

 ous legumes were again noticed. 



The subterranean legumes of A. monoica and A. Pitcheri 

 were large, thick, deep purple-pink in color, and varied from a 

 half to three-quarters of an inch or sometimes an inch in 

 length. No difference could be distinguished in the appear- 

 ance of these legumes. 



Those produced by the Strafford variety were small, more 

 spherical, none exceeded a half inch in length, and they were 

 strikingly colorless. Here and there, a legume showed a 

 pinkish hue ; but as a whole, the fruits presented a pure white 

 appearance as the underground parts of the plants were 

 exposed. 



It may be that we have here a new variety. I have noticed 

 the following differences — but doubtless there are others. 

 The Strafford form exhibits a want of dark purple hue in the 

 stem, as well as in the flowers and legumes ; the aerial seeds 

 too are much smaller than those produced from the purple 

 flowers. The plant is less hairy, and possesses fewer axillary 

 runners than the ordinary type. 



My intention is to plant the seeds, both subterranean and 

 aerial, and ascertain whether these peculiarities persist. In 

 the coming summer, the plants of the purple-flowered and the 

 white forms will be carefully compared.
