sistance and advice in the preparation of this catalogue. His ad- 

 vice in arrangement, classification, and nomenclature has been con- 

 stantly sought by us and freely given by him ; yet, seldom has his 

 advice been closely followed. Nevertheless, his counsel has neces- 

 sarily been of great service. 



The foundation for this catalogue is Smyth's Checklist of the 

 Plants of Kansas, 'published in 1892 (which was Smyth's third 

 list, previous ones having been published in the transactions of the 

 Graywood Botany Club and the Bulletin of the Washburn Labora- 

 tory of Natural History), since which time much has been learned 

 of the botany of the state ; yet the classification of that modest 

 work has been departed from mainly in reversing the general ar- 

 rangement in keeping with present-day methods and the introduc- 

 tion of some harmonic terms in classification and in description. 

 A fourth catalogue, on a difPerent plan, entitled "Plants and 

 Flowers of Kansas," by the senior author, was published in 1900, 

 by Crane & Co., of Topeka, in their "Twentieth Century Classics," 

 thus making the present catalogue Smyth's fifth list of the plants 

 of Kansas. 



Quasi-new terms ( acicles and laminodia ) are here introduced 

 for the leaves of some gymnosperms and monocotyls, which difiPer 

 fundamentally and intrinsically from the ordinary leaves of dicotyls 

 as much as do bracts, scales, sepals, phyllodia, and other forms 

 of leaves to which are applied special terms. It is expected that 

 these terms will commend themselves to botanists in general, and 

 will, if worthy, meet their approval. 



In the following pages herbaria in which specimens of the 

 plants are contained are indicated by initials as far as known. (A) 

 represents the herbarium of the Kansas Agricultural College, 

 which is very full as to representatives of the Kansas flora, and 

 which has been frequently consulted ; ( S ) is the State Herbarium, 

 in charge of the principal author and made in toto by him ; it also 

 stands for the private herbaria of the authors, as well as the herba- 

 rium of Professor Schafl:'ner, which is richly supplied with Kansas 

 plants, and is a part of the foundation of this catalogue; (U) is 

 the herbarium of the Kansas State University, which the principal 

 author has consulted, and of which the authors have a partial list 

 of the plants. A few names are included on the authority of Mr. 

 F. V. Coville, botanist of the Department of Agriculture at Wash- 

 ington. 



That there should be errors in the present catalogue is unavoid- 

 able and rather to be expected. All such discovered in season will
