480 BOTANICAL INFORMATION. 
in the finest preservation; and the localities, with other 
particulars, have been carefully recorded by Mr. Geyer. 
They were chiefly gathered during the autumn, and latter: 
part of summer: the earlier, and perhaps most interesting 
collections were unfortunately lost’ A Catalogue of this 
Herbarium was published by our excellent friend Dr. Torrey, 
in the Appendix to M. Nicollet’s ** Report intended to illus- 
trate a Map of the Hydrographical basin of the Upper 
Mississippi River." 
This collection is peculiarly interesting, as illustrating the 
Botany of a region lying considerably to the south* of those 
Fremont up the Desmoines river, Lower Iowa territory, being chiefly, how- 
ever, occupied in surveying. In the botanical collection then formed, which 
suffered much by the filling of a canoe, he had several new plants, which are 
~ placed in the Herbarium of Dr. Engelman at St. Louis, and they cannot 
well be in better hands, for that gentleman has himself successfully explored 
the botanical riches of a great part of the state of Arkansas, and is fami- 
liar with the Flora of St. Louis. During the year 1842, Mr. Geyer 
"directed his attention to the Botany of the Upper Illinois country; where, 
especially about Sougamon river, he formed the Herbarium which was 
first offered for sale. In 1843, he commenced the intrepid journey, the 
botanic results of which are now about to be detailed. : 
* Other plants were collected by the officer, Lieut. J. C. Fremont, as 
detailed in that gentleman's “ Report on an Exploration of the country 
lying between the Missouri river and the Rocky Mountains, on the line 
of the Kanzas and Great Platte rivers." These are also described by 
Dr. Torrey in an Appendix published in 1843. Our attention has been 
directed to the Genus “ Fremontia” published in this Appendix, which, no 
doubt, from the limited circulation of the “ Report," has not attracted the 
attention it deserves ; and hence Botanists have been led to notice the plant | : 
under another name. It is the Sarcobatus Mawimiliani of Nees, described by — 
Dr. Seubert in the ‘ Botanische Zeitung," for Nov. 1, 1844; but was pre- — 
viously noticed under the same name, in a work as little likely to fall into 
‘the hands of Botanists as the “ Report" above mentioned, namely, 
“ Prince Maximilian v. Wied Reise ins innere Nordamerika," I. p. 510, — — 
and IL. p. 447. It is there doubtfully referred to Urticeæ, and said to be — 
the “ pulpy Thora” of Lewis and Charles Young. Some observations OD — 
this Genus will be found at p. 1, of the present volume of our “Journal,” 
3 from the pen of Dr. Lindley, who was, "however, unacquainted with the 
character of Fremontia, and we shall only render justice to Dr. Torrey —— 
| by occupying a portion of these pages with a transcript from it. —
