wings may be replaced by the light blue or striped white 

 described for apricus or the whole corolla may be white 

 or pink and white. 



All the dark blue, light blue and striped white plants 

 had a white front on the banner with blue, blue-green, 

 or no spots in the groove. White corollas had either 

 white or lemon-yellow fronts with or without the dark 

 spots. Normal dark blue plants have the color uniform 

 on banner and wings or else with a deeper spot at the 

 angle where the refiexed banner joins the wings. In light 

 blues this spot may be dark blue, light blue, greenish blue 

 or absent altogether. Whites have this spot faintly blue, 

 bright orange, or absent. The orange spots may occur 

 with either white or lemon-yellow fronts. 



A reddish-purple corolla was found on a number of 

 plants which were distinguished by unusually large and 

 fine flower clusters. In some of them the flowers had 

 fallen and pods formed on some earlier branches. The 

 pods in every case were of a very peculiar type. Instead 

 of the elongated, nearly straight and somewhat flattened 

 and constricted type commonly found these plants had 

 pods long, tapering, nearly round, and frequently much 

 coiled. This was at first supposed to be due to attacks 

 of insects or fungi. Diligent search failed, however, to 

 show any such infection or infestation. And when it 

 was later discovered that the plants which would pro- 

 duce these curly pods could be identified in the early 

 flowering stage it was realized that this whole group of 

 characters constituted an interesting variation. A num- 

 ber of plants were labelled and some bagged for seed. 

 Although many seed capsules were examined, no good 

 seed were secured. It appears highly probable that this 

 form is completely sterile, though there is a chance that 

 the failure to set seed may have been due to un- 

 favorable weather. In 1920 neither this nor any of the 

 other variations were to be found in that same field. 

 Diligent search, in fact, has failed to discover it any- 

 where. It is much to be regretted that good seed of this
