168 KANSAS ACADEMY OF SCIENCE. 
THE KANSAS UREDINEAE. 
BY ELAM BARTHOLOMEW, STOCKTON, KAN, 
Read (by title) before the Academy December 30, 1898. 
In preparing a state monograph on this interesting and widely distributed 
group of fungi—the rusts—the author has sought to bring together, in a small 
compass, all species known to occur in Kansas, and to indicate in popular lan- 
guage, as nearly as may be possible, their geographical distribution, frequency 
of occurrence, and destructive qualities to their several host plants, a list of which 
will be found at the end of the catalogue. 
Since the publication of the list of seventy-five species compiled by Doctor 
Kellerman and Mr. Carleton in Trans. Kan. Acapb. Sct., Vol. X, pp. 88-99, 1886, 
no effort has been made to catalogue the Uredineae of this state. During the 
twelve years that have elapsed since the publication of that list, by the assiduous 
labors of our collectors at various locations, the number of known species has 
more than doubled, and there are doubtless many yet to be added. 
Of the 154 species and varieties here recorded Kansas is given as the type 
locality of twenty-six. In each case where the word ‘‘type’’ follows the date of 
collection it will be understood to indicate the date and locality of discovery. 
All collections made in Rooks and Phillips counties, as indicated in the body 
of the catalogue, have been made by the author, unless otherwise specified. 
Where collections have been made by him in other counties, to prevent confu- 
sion, the abbreviation ‘‘ Barth.”’ will follow the locality and date of collection. In 
all other cases the collectors’ names are given in full. All species here enumer- 
ated, with the exception of one or two, are represented in the author’s herbarium 
and that of the State Agricultural College, at Manhattan. 
At this time of critical readjustment and revised nomenclature, many ob- 
stacles must be met and overcome if one expects to make a very near approach 
to accuracy. Yet, after all his painstaking efforts, he is almost sure to awake to 
the somewhat annoying realization of the fact that what was an accepted scien- 
tific truth yesterday may be, in more ways than one, an error to-morrow! Some 
revision has been made in host nomenclature where cellectors were obviously in 
error, but generally the revision in phanerogamic nomenclature, of the latest pat- 
tern, has not been followed. 
The use of technical terms has been avoided as much as possible, with a view 
to making the catalogue of practical utility in a popular sense, yet scientific names 
have been adhered to strictly, that its scientific value might not be impaired. 
Some stress has been put on the matter of citation of original publication, 
that the age in nomenclature may be readily seen and referred to by.collectors 
and students generally, without necessity of referring to the many publications 
in which the original descriptions are found. Along this line it will be noted 
that not only the months are given in which the several species occur in the 
greatest abundance, but the years of collection are also given for the benefit of 
those who may follow this work in the future. 
The various reasons should be obvious to all. The very near approach to 
each other, at least in gross form as well as more minutely, of Puccinia helian- 
thi, Schw., Puccinia tanaceti, DC., and Puccinia variolans, Hark., has 
seemed to make it necessary, for the purposes of this catalogue, to separate these 
forms more along the line of host plants than on any well marked characters of 
the fungi themselves. Hence, all forms on Helianthus have been referred to P. 
helianthi; those on Artemisia and Actinella to P. tanaceti; those on Aplo- 
pappus to P. variolans.
