The lilac collection, about 250 plants adjacent to the Rose 
Garden on the west, has of necessity received little attention for 
a number of years. It was found that various preliminary maps, 
made before the Rose Garden was constructed, far from represent 
the present arrangement of the plants. Many shrubs have been 
moved and many service labels attached to branches have been 
lost due to borers and other causes. To facilitate accurate map- 
ping of the collection, numbers have been painted on the twenty- 
eight Rose Garden posts, and a few small boulders have been put 
in various places to serve as points of reference. New maps have 
been made by Mr. Joseph Pollio, a CWA draughtsman. Informa- 
tion about plants and specimens has been correlated so far as pos- 
sible under three groups: White Forms, Colored Single lorms, 
and Colored Double Forms. We hope to get the greater part of 
the collection labeled in the spring of 1934. 
VIBURNUMS 
A geographical arrangement adopted last fall for this important 
horticultural genus much simplifies the study of the group, and 
enhances its educational value as an exhibit. We have at present 
12 American, 3 European and 22 Asiatic species. These figures 
reflect, in general, the relative number of species of Viburnum in 
each of the three continents. The Cornus and Spiraea groups 
especially need similar rearrangement. 
Maps or TREES AND SHRUBS 
We have adopted a smaller form for our maps with many small 
squares. These maps are more easily carried about the Garden
