EARLY IOWA LOCALITY RECORDS 
113 
Platte, on the Iowa side, the following statement is made: “On 
the precipitous and almost naked argillaceous hills, which here 
bound the Missouri valley, we found the Oxytropis lamberti 
and the great flowering pentstemon; two plants of singular 
beauty. Here also w^e saw, for the first time, the leafless prenan- 
thes, the yellow euchromia, and many other plants.” The 
“pentstemon” is evidently Pentstemon grandiflorus ; the “leaf- 
less prenanthes” is Lygodesmia juncea; and the “yellow eu- 
chromia” is Castilleja (Euckroma) sessilifior a. 
Other less definite notes also occur, but they probably do not 
refer to Iowa. 
The Nicollet report also contains some references to plants 
which may have been observed in Iowa (see p. 29), and in addi- 
tion to this includes, on pp. 143 to 165, as Appendix B, a “Cata- 
logue of plants collected by Mr. Charles Geyer, under the direc- 
tion of Mr. I. N. Nicollet, during his exploration of the region 
between the Mississippi and Missouri rivers: By Professor 
John Torrey, M. D.” This contains specific references to plants 
collected at or near “Council Bluff”, here undoubtedly the 
Council Bluff of Lewis and Clark on the Nebraska side of the 
river. On pages 144 to 168 of this catalogue forty-eight species 
of plants are specifically reported as occurring at or near Coun- 
cil Bluff, and these of course belong to the flora of Nebraska. 
Several other species are less definitely reported from the same 
general region, but it is impossible to determine on which side 
of the Missouri they were found. 
This catalogue also contains certain Iowa species which were 
collected in other parts of the state. The Nicollet expedition 
visited the Spirit lake region, and the following specific refer- 
ence to plants from that region are made : 
Euonymus atropurpureus. Woods, Spirit Lake; common; p. 147. 
Dalea alopecuroides (Willd.). Banks of Spirit Lake, etc; p. 148. 
Darlingtonia (i.e., Desmanthus) hracTiylo'ba var. glandulosa (Torr. & 
Gray). Gravelly banks of Spirit Lake; p. 148. 
Aster Novae-Belgii (Linn.), and var. minor (Torr. & Gray). Borders 
of Spirit Lake; p. 151. 
Xanthiwm ecMnatum (Torr. & Gray). Banks of Spirit Lake and 
headwaters of Little Sioux river; p. 152. 
Artemisia biennis (Nutt.). Arid banks of Spirit Lake, etc.; p. 153. 
Solanum nigrum (Lmn.). Sandy banks of Spirit Lake; p. 156. 
Physalis viscosa (L.). Sandy banks of Spirit Lake; p. 156.
