Apart from additions to the systematic collections, the fol- 

 lowing plantings were made: Ii6 trees in the wild flower section, 

 100 Ginkgo trees on the Museum embankment, numerous 

 plants of the Prairie Rose, Rosa setigera, back of the Azaleas 

 near the Malbone Street entrance, and loo Red Bud, Greets 

 canadensis, on the border mound west of the Walnut family. 

 About 50 roses (Paul's Scarlet Climber) were planted on the 

 trellis on the east side of the children's garden to replace un- 

 satisfactory seedling forms, and 147 feet of stepping stone walk 

 was constructed in the children's formal garden. 



International Seed Exchange 



During 1924 seeds of nearly 1,000 species and varieties of 

 plants were collected in the Garden. With the addition of 

 seeds collected elsewhere by Dr. Gundersen and others, this 

 admitted of the inclusion in the Exchange Seed List of 890 names 

 of plants of which seeds were available for distribution. The 

 collection, cleaning, filing, and distribution of seeds in this 

 connection consumes a great deal of time. Its value to the 

 Garden, however, for many reasons, apart from the opportunities 

 it offers of adding rare plants to our collections through exchange 

 with other Botanic Gardens, is such that it should be considered 

 an indispensable part of our activities. The distribution of 

 seeds the past year to various countries is shown below:
