Excerpt from A Plant-Disease Survey in the Vicinity of San Antonio, Texas

During the summer and fall of 1909 and the winter and spring of 1910 a plant-disease survey was made of a portion of Texas in the vicinity of San Antonio. The Object of this work was to determine the diseases which were prevalent with a view to a later and more detailed investigation of those which are either new or imperfectly known.

The emphasis has been placed upon the diseases of plants due to bacteria, fungi, or other parasites, but environmental factors have not been overlooked. The field is an exceedingly fruitful one, since but little has been published concerning the parasitic fungi or plant diseases of this part of the country. Besides the report of Jennings issued some years ago, and a short list by Cooke but few scattered records of Texas fungi exist. It will not be surprising, then, if a detailed examination of a restricted area should show many new and interesting forms.

The work outlined in this report was carried out by the writers, with headquarters at the University of Texas. Acknowledgment is here made of the helpful suggestions of Mr. W. A. Orton. Mrs. F. W. Patterson, and Miss E. C. Field, of the Department, have very kindly assisted in working over the doubtful specimens and in the determination of most species which appeared to be new, with the exception of the Uredinales, which were submitted to Mr. F. D. Kern, Lafayette, Ind. Several specimens were also referred to Prof. C. H. Peck, Albany, N. Y. In addition, the senior writer visited the herbaria at Washington and the New York Botanical Garden in order to compare our material with their collections which are rich in type specimens.

Specimens have been deposited in the herbarium of the University of Texas, at Austin, while duplicates, including type specimens.
