A Study of the Forage Plants of South Dakota with Their Fungous and Insect Enemies

<p>The main object of this study being a better acquaintance with fungous parasites, the work on the host plants has been considerably abridged in order that the discussion might be shortened. It was the plan at first to include in this paper a carefully written description of each of the principal forage plants of the state. The futility of such a plan, however, soon became apparent, and it was accordingly decided to omit the description and include simply Distribution,</p> <p>Habitat, Value as Forage, and the Fungous Parasites of each host. There are, therefore, several of our best forage plants omitted from this paper because they were not found diseased. With the exception of five or six species, all of the material here described was collected during the summer of 1892. The greater part of the collecting was done by myself, but many contributions were made by T. A. Williams, E. N. Wilcox, and J. J. Thornber. While at the University of Nebraska, last winter, P.A.Rhydburg kindly allowed me to examine his collection of grasses from the Black Hills of South Dakota. From this source I obtained two very valuable things, a Puccinia and an Erysiphe. All but four of the species described here were collected on the east side of the Missouri river, within the borders of South Dakota. The other four were collected in the Black Hills of this state. Nearly all of the determinations were made at the State University of Nebraska during the winter of 1892-93. While there access was gained to a valuable herbarium, literature, and apparatus, which could not have been obtained otherwise.</p>
