twice or more during the season in order to secure plants 
of the spring and autumnal floras, as well as to obtain flower- 
ing and fruiting specimens of the same species. Upwards 
of 10,000 herbarium specimens were collected during the sea- 
son, which will be of the utmost value in elaborating the 
proposed “Flora of the Southwest.” 
Use of Herbarium by Outside Botanists—Several special- 
ists from different parts of the country have visited the her-

in technical genera and especially to consult type material. 
Numerous loans have been made to specialists engaged in the 
monographiec study of particular groups of plants.
