JANUAEY 1 TO MARCH 31, 1924 3 



A Mexican relative of the iris {Tigridia pavonia, No. 58573) presented by 

 Mrs. Zelia Nuttall, of Coyoacan, should appeal to those who care for delicate 

 flowers; although the latter are somewhat short lived, in mass planting the 

 effect of successive flowering is very striking. 



Special attention should be directed to Populus maximowiczii (No. 58483), 

 a hardy and stately tree from Manchuria, which is proving of great value in 

 the colder and drier areas of the United States where poplars are particularly 

 desirable. The distinctive rugose character of its foliage, which appears more 

 than a week before that of other trees, makes it unique among poplars. Bud- 

 wood has been presented by A. D. Woeikoff, director of the experiment farm 

 at Echo, Manchuria. 



The botanical determinations of introductions have been made and the nomen- 

 clature determined by H. C. Skeels, and the descriptive matter has been pre- 

 pared under the direction of Paul Russell, who has had general supervision of 

 this inventory.
