In securing information, collecting material, and organizing and preparing the manuscript, the writer received invaluable aid from Mr. H. B. Parks of the Texas Experiment Station, who identified much of the native material; from Mr. J. E. Pittman of the Texas Highway Department, who supplied a number of plants and gave us the benefit of his many years of experience in growing and caring for ornamental plants; from Mr. Harry Foehner, roving reporter of the Herald-Star-Monitor, who assisted with the photographic work; and from many of our local nurserymen and landscape architects, who have a practical knowledge of the merits and weaknesses of most of our plant material.
