Ill 
Because of the special nature and value of intact exsiccati 
collections, the three found in the Cheever Herbarium have been kept 
intact, and together treated as a separate section. The species therefore 
were not included in the index which follows, but will be found in a 
separate "Index to the Exsiccati of the Cheever Herbarium." 
Addendum Boxes B-36 to B-41 
The addendum at the end of this index contains a fair number of slides 
belonging to both Group I and Group II. These slides were discovered after 
the collection had been organized and could not be included in the index
