copies of old records, as in the writer’s papers on loess, etc., 
apply to Council Bluffs, Iowa, and not to the Nebraska locality! 
The older reports on Iowa plants and animals follow : 
PLANTS. 
The earlier records of plants, namely those in the Lewis and 
Clark and the Lon^ reports, are for the most part very unsatis- 
factory both as to identification (general and common names 
being used in part), and as to exact localities. Clark’s Journal 
contains references to plants, mostly trees, which were observed 
as the party ascended the Missouri along the present boundary 
of Iowa, but it is usually impossible to determine on which side 
of the river they were observed, as they were mostly bottomland 
species. The only definite Iowa reference is that to the black 
walnut, which was observed on the return trip near Floyd’s 
grave, near the present site of Sioux City.^'^ 
Concerning the plants collected by the Lewis and Clark ex- 
pedition Pursh reports as follows d® 
' a small but highly interesting collection of dried plants 
was put into my hands by this gentleman (i.e., Meriwether 
Lewis, then governor of Upper Louisiana;) in order to describe 
and figure those I thought new. The collection of plants just 
spoken of was made during the rapid return of the expedition 
•from the Pacific Ocean towards the United States. A much 
more extensive one made on their slow ascent towards the Rocky 
mountains and the chains of the Northern Andes, had unfortun- 
ately been lost, by being deposited among other things at the 
foot of those mountains.” The latter collection probably con- 
tained some Iowa material. The small collection submitted to 
Pursh probably contained none, as all locality references to it 
in the text suggest localities west of the Missouri river. 
In the account of the Long Expedition comparatively little 
is said of the flora, but in the description of the return of Major 
Long from St. Louis to Council Bluff a footnote, evidently re- 
ferring to Iowa, states^^ that a Caenothus (smaller than C. 
americana), Amorplia canescens, and Symphoria (i.e., Symphori- 
oarpos) racemosa ‘^are almost the only shrubs seen on the prai- 
rie.” Again, on the following page, in both editions, in connec-
