is often lacking as to whether the varieties were originally intro- 

 duced from Japan or grown from seedlings. 



The usual diseases and pests were in evidence. Several plants 

 were lost through the decay of the hhrous roots. More serious 

 trouhle seemed to he associated with the maggot or larva of a 

 fly which has l)een identified as Cliacfopsis fidvifroiis. A great 

 many ])lants died during and after the l)looming season and, in 

 most cases, it was possil)le to find the larvae in the dying leaves. 



Miss Louise B. Mansfield made for us several additional water- 

 colors of the Japanese varieties, as well as some of the other species. 

 These are valuable additions to our collection of colored illus- 

 trations. 



Siberian and uiisccllaiicoiis beardless Iris 



Since most of the plants of this group were transplanted in 

 the fall of 1928, they were not thoroughly established and did 

 not give abundant bloom during the past year. The plants, how- 

 ever, grew quite well and in another year should bloom vigorously. 



Several of our own seedlings bloomed for the first time and 

 among them there were several that were particularly interesting, 

 especially those grown from Dorothea Iv. A\ illiamson. This 

 variety is a hybrid between Iris fuha and /. foliosa and is well 

 known as a valuable garden plant. The flower was selfed in 

 1925 and the seed collected. A few seedlings were secured, some 

 of which bloomed for the first time in 1928 and still others during 

 the past season. The new plants are unusual in the combination 

 of color, and extremely interesting in view of their parentage.
