Inasmuch as most of the published information is distributed in a large number of European botanical works, it has seemed well to assemble those data to accompany the American data in this report. The specific conditions mentioned for the occurrence of P. bulbosa in the literature reviewed by Halperin (2, 3) include dry soils, sand or sandy soils, roadsides, glaciers, infertile, rocky, and lime soils; open sunlight and forests; elevations from sea-level to 7,000 feet; and cultivated fields. Rouy (8), Vilmorin (10), and Knoche (5) also report P. bulbosa in several of the above-mentioned environmental conditions. Vilmorin (10) and Knoche (5) state that this grass is found in shade.
