 be conveniently reached. A study of the material, however, 

 has brought to light a gratifying number of novelties and 

 leads to the conclusion that if such superficial collecting yields 

 new species, a careful exploration would yield many more. 

 President Aven Nelson of the University of Wyoming, whose 

 work on the botany of the Rocky Mountain region is so well 

 known, has kindly supplied the names for the plants collected

 species that appear to be new. A more general account of our
