APPENDIX TO THE 
CATALOGUE OF THE FLORA OF NEBRASKA. 
BY H. J, WEBBER. 
(Presented October 18th, 1891.) 
Considerable material and information having accumulated since 
_ the publication of my Catalogue of the Flora of Nebraska, in the 
Annual Report of the Nebraska State Board of Agriculture for 1889, 
it is thought best to bring this together as an appendix to the Cata- 
logue. 
In the printing of the ‘‘ separates’’ of the Catalogue, for some 
unaccountable reason, the type of the first eighty pages was reset 
without proof-reading, thus leading to many typographical errors 
in the “separates ’’ that do not occur in the original as printed in 
the body of the Report. I have thought best to add a list of such 
~igichenn soi as I have noted, reference et in every case to the ° 
** separates.”’ 
In the main Catalogue some species not seen by me or by collect- 
ors aiding in the preparation of the Catalogue, were reported on the 
authority of Gray’s and Coulter’s Manuals, etc. Many of these 
having since been collected, a list is given with a few distribution 
notes, under the heading, — Notes on species before reported. — 
I have also included in this list a few corrections that it has been 
found necessary to make in the identification of species before 
reported. 
In the appendix proper the plan of arrangement followed in the 
Catalogue has been carried out. The names of those reporting 
Species follow in every case the name of the species reported as 
it occurs in the appendix. The collector whose name follows the 
Species, it must be understood, is to be taken as the authority for 
: its occurrence, as in many cases I have not had the opportunity to as 
ce at te 
v species 0} or in the Herbarium of the University of Nebraska. <
