and extensive suites from other localities are wanted to determine positively 

 how far the three varieties are permanently distinct forms from one another 

 and from D. lasiophylla, Wahlenbergii, and incana. D. Armena has much 

 smaller, shorter pods, and stout pedicels. Thomson remarks that the 

 flowers are hoth white and yellow. Mr. Winterbottom's specimens (var. y) 

 clearly resemble Boissier's D. Persica.
