Park service, a project which deserves the strongest support of 
all who are interested in the plants and animals of the southern 
Appalachians. 
The material collected during the summer was sent from time 
to time to the Brooklyn Botanic Garden, and will be distributed 
through the seed exchange and through departmental exchanges 
of herbarium material. 
Tne HerRBARIUM 
Statistics of the herbarium collections will be found at the 
end of this report. The phanerogamic herbarium now contains 
upwards of 100,000 specimens of flowering plants and ferns, 
represented chiefly by material from the United States. Its com- 
pactness and the close incorporation of reference books greatly 
facilitates the identification of collections, and has undoubtedly 
led to the greatly increased use of the herbarium by visitors. By 
the removal of one of the storage cases, some additional working 
space was obtained and the appearance of the herbarium has been 
ereatly improved, but we are still limited in table space for visit- 
ting botanists. The greatest need at the present time is a well- 
trained student who can help with the organization of the collec- 
tions and participate in publications based on the material in the 
herbarium. As in previous years, we are greatly indebted to the 
government relief workers who have been engaged in mounting 
plants, in stenographic work, and in sorting material. 
Locat FLora SECTION 
This area continues under my care. The work of clearing out 
exotic material such as lilac and privet bushes, 4ilanthus, willow 
trees, hawthorns, and other ornamentals planted long ago, pro- 
ceeds slowly from year to year at a rate conformable to the growth 
of the more recently planted native trees and shrubs. As a gift 
from Dr. James N. Currie, we received an unusually large clump 
of showy ladies’ slipper (Cypripedium hirsutum), to me the most 
spectacular of all our native plants. The soil has been carefully 
prepared for growing this unusual orchid, and next spring it 
should be a brilliant addition to the Local Flora Section. Of in- 
terest during the past vear were the excellent growth of Trillium 
undulatuim and Dodecatheon Afeadia, the thriving colonies of Viola
