PREFACE. 



The following Catalogue is intended to be an almost complete list of the Phaenogamous 

 and higher Cryptogamous Plants of Illinois, with the more common introduced plants. The 

 latter are printed in italics. 



My own botanical explorations in the State having been confined to Henderson county, 

 the Catalogue is made up mostly from lists and notes furnished by the following well known 

 Illinois botanists : 



M. S. Bebb, Fountaindale, Winnebago Co.; 

 Dr. Geo. Vasey, U. S. Botanist ; 

 .Miss Mary E. Holmes, Rockford ; 

 Miss M. E. B. Norton, Rockford ; 

 Prof. H. H. Babcock, Chicago : 

 Henry F. Munroe, Esq., Chicago ; 

 Rev. E. J. Hill, Englewood, Cook Co. ; 

 And by Dr. Geo. Engelmann of St. Louis, 



Dr. Frederick Brendel, Peoria ; 

 Prof. John Wolf, Canton, Fulton Co. ; 

 Prof. S. A. Forbes, Normal, McLean Co. ; 

 Dr. S. B. Mead, Augusta, Hancock Co. ; 

 Elihu Hall, Esq., Athens, Menard Co ; 

 Dr. J. Schneck, Mt. Carmel, Wabash Co. ; 

 Prof. G. H. French, Irvington, Washington Co. 

 and the late Dr. I. A. Lapham of Milwaukee. 



The following 14 species are given on the authority of Gray's Manual : Draba cunei- 

 folia, Nutt. ; Chrysogonum Virginianum, L. ; Bidens Beckii, Torr. 5 Verbesina Virginica, L. : 

 Bumelia lanuginosa, Pers. ; Utricularia biflora, Lam. ; Stachys hyssopifolia, Mx. ; Chaunelir- 

 ium Iuteum, Cray ; Heteranthera limosa, Vahl. ; Carex dccomposita, Muhl. ; Trisetum palustre, 

 Torr. ; Erianthus alopecuroides, Ell. ; Houstonia minima, Beck. 



Plants confined to the Northern part of the State are marked N. ; Central C, and Southern 

 S. In many cases the information at hand was not sufficient to indicate the frequency of the 

 plant, but where it seemed to be rare I have usually named all the counties wherein it has 

 been found by the botanists named above. 



When unacquainted with the habitat of the plant I have usually copied from Gray's 

 M v\ i rAL ; the arrangement of species in the same excellent work has also been followed closely.
