with white stripes or veining. In other, and rarer, cases 

 it is apparently a white flower veined with blue. Seeds 

 of this type were collected and have since been grown 

 under the name of striped white. This first season it 

 was not realized that the two lighter forms were distinct. 

 Fortunately the seeds of each individual plant were saved 

 and gro^\^l separately, so that the distinction became evi- 

 dent in 1917, the first year in which successful cultures 

 were grown. 



Pink apricus were also fairly common that year and 

 have been occasionally noted since. Seeds were saved 

 and have since been grown. 



Two white forms were observed that year. One ap- 

 peared to be plain white. This type has been frequently 

 observed since in this and other species. A single plant 

 was also observed in which the color was a cream or 

 yellowish white. Seeds of both sorts of plants were saved 

 but have so far failed to grow. 



A few scattering observations were made on nanus 

 from year to year, but it was not until 1917 that a field 

 was found in which variations were numerous and con- 

 spicuous. Pinks, light blues, striped whites, and whites 

 were all abundant in a field near the town, of Woodside. 

 Specimens of all. these types were staked out for seed but 

 unfortunately attracted the attention of the small boy 

 and no seeds were secured. In 1919 3 fields were found 

 some 3 miles west of the university in which numerous 

 variations were in full bloom. A careful study was made 

 and an attempt made to discover and describe every 

 variation. Twenty-seven plants were labeled and de- 

 scribed for seed collection. They represented 12 separate 

 and distinct variations or combinations. All the varia- 

 tions but two are concerned with flower color. In the 

 description of nanus it will be noted that the normal 

 plant has a blue and white corolla having a reflexed 

 banner with a white front down the middle of which there 

 is a groove marked with a number of small dark spots. 

 In the variants the normal dark blue of the banner and
