brief keys to include the species growing in our Garden at the 

 present time, including also plants we think might make desirable 

 additions. A number of species of D'lanthus were placed in the 

 nru'sery. It is desirable to expand the trial of special groups of 

 herbaceous plants in the nursery to avoid so much changing in 

 the beds. 



Iris 



Dr. George M. Reed reports that twenty-three varieties were 

 received by exchange ; of Japanese Iris, one from Cedar Hill 

 Nursery, Brookville, New York and twenty from l^lowerfield Bulb 

 Farm, Flowerfield, New York ; of southern sjiecies, tw-o from 

 Mr. Percy Viosca, Jr., New Orleans, La. 



Labels 



We continue to have trouble from removal of labels, especially 

 in the rock garden. After more than twenty years' exposure 

 various troubles are coming to our label holders in the beds. For 

 some time I have been in correspondence w'ith a western firm 

 regarding label holders, and some experimental models have been 

 made. 



Conservatories 



Four transparencies rejiresenting the tapping of rubber trees, 

 a banyan tree with aerial roots, coconut rafts floating down a 

 tropical river, and chocolate trees in fruit were completed by Mr. 

 Louis Buhle and colored watli mineral paints resistant to sunlight 

 by Miss Elizabeth Bonta. These will be hung in the conservatories 

 early next year. 



During the winter I have had consultations with members of the 

 staff regarding possible improvement of the conservatories. It is 

 becoming yearly more difficult to find adequate greenhouse space 

 for experimental work, study collections, propagating, potting, 

 bringing exhibition material to perfection, and other needs besides 

 that of maintaining exhibits open to the public.
