twinflower (Linnaea), bunchberry (Cornus canadensis), and the 
creeping snowberry (Chiogenes), has been most gratifying. The 
sand barren plants, such as Corema, sandwort (Arenaria squar- 
rosa), bearberry (Arctostaphylos), and others have been satis- 
factory. These plants have become thoroughly established, and 
their culture is no longer a problem. 
HERBARIUM 
The herbarium was enriched by the collections made by me in 
Ecuador and Peru, while working under funds from the John 
Simon Guggenheim Memorial Foundation. Much of the dried 
material which was obtained is now ready for distribution to 
other botanical gardens. The specimens, which have been de- 
rived through exchange with other institutions, will be found in 
the adjoining lists. A large amount of material, especially Cy- 
peraceae, is Coming in from various sources for determination.
