67006. Iris setosa Pall. Arctic iris. 



According to Dykes (Irises, p. 64), this 

 was originally described as an Asiatic plant, 

 but forms that can not be separated from it 

 are found in North America. At least half 

 a dozen forms come true from seed. The 

 peculiarity of this iris is that the standards 

 have dwindled until they are only small 

 points about half an inch long, but their 

 disappearance is usually counterbalanced by 

 the increased size of the falls. The color is 

 usuahV blue, but some shades are so light as 

 to be almost gray.
