known been included. Prof. C. E. Bessey, Mr. P. A. Rydberg and 
Mr. T. A. Williams, have collected extensively since the issue of the 
Catalogue and have kindly furnished me annotated lists of the species 
they have discovered which were not before reported. I cannot 
thank them too much for their tedious, painstaking labor. 
Prof. G. D. Swezey, of Doane College, Crete, Nebraska, has issued 
a list of ‘‘ Nebraska Localities for Flowering Plants in the Herbarium 
of Doane College,’’ which includes a number of species not reported 
in my Catalogue. Prof. Swezey kindly sent me specimens of most 
of the additions for examination. My notes (where desirable) on 
those examined will be found in the text of this appendix. I have 
to thank Prof. Swezey for this and several other favors rendered. 
Ir. R. N. Pound, Mr. A. F. Woods and several others reporting 
interesting discoveries, have been duly credited in the text. 
For sid in the identification of species reported on my authority 
in this appendix, thanks are due to Drs. N. L. Britton, C. F. Mills- 
paugh, Geo. Rex, Wm. Trelease and Sereno Watson; Professor L. 
H. Bailey, Mrs. Elizabeth Britton, Mr. Henry Willey, Mr. M. 5%. 
Bebb, Mr. F. V. Coville and Mr. A. 8. Hitchcock. 
Lastly Iam pleased to acknowledge the general ail and support 
of Dr. Wm. Trelease and Dr. C. E. Bessey throughout the prepa- 
ration of the paper. 
This appendix contains 432 species not before reported; of which 
9 are Protophytes, 20 Zygophytes, 7 Oophytes, 117 Carpophytes, 13 
Bryophytes, 2 Pteridophytes, and 264 Anthophytes. 
The Catalogue contained 1890 species and varieties, of which 39 
were Protophytes, 95 Zygophytes, 20 Oophytes, 691 Carpophytes, 47 
Bryophytes, 17 Pteridophytes, and 981 Anthophytes. 
Thus the Nebraska Flora as at present known contains 2322 
species and varieties, of which 48 are Protophytes, 115 Zygophytes, 
27 Oophytes, 808 Carpophytes, 60 Bryophytes, 19 Pteridophytes, 
and 1245 Anthophytes. 
In conclusion I wish again to thank those who have so kindly 
aided me, and to express my gratification that the people of the State 
of Nebraska are showing increased interest in their not uninterest- 
ing flora.
