430 THE AMERICAN NATURALIST [Vol. LV 



In 1914 apricus and pipersmithii were very numerous 

 in a field near the university and much study was devoted 

 to them. Besides the pink forms already mentioned a 

 considerable number of other color variants were noted 

 and seed collected of some of them. Seeds were collected 

 of both the pink and blue forms of pipersmithii and have 

 since been cultivated. Smith (10) had earlier collected 

 seeds of these varieties, but had not been successful in 

 cultivating them. Jepson (7) makes note of the variabil- 



ity of nanus and Smith mentions variations of size of 

 plant and flower in apricus. 



The normal color of apricus is dark blue and white. 

 After some study it became very obvious that, mixed with 

 the usual types, there were occasional plants with a de- 

 cidedly lighter blue. One variation consists in a mere 

 lightening of the blue. This type was called light blue
