Text Appearing Before Image: to a depth of 3 feet, at whichdepth many of the roots terminate in rather well-branched tips, while otherspenetrate to a depth of 4 feet or slightly beyond. A maximum depth of 4 feet3 inches was recorded for several of these tiny, hairlike termini. Branching isespecially well developed in joints between the lumps of hard soil. The olderroots are ashy-gray in color, and are provided with a rather papery cortex,which upon removal reveals the tough, light-yellow stele. The deeper rootsare threadlike and are very fragile and usually well branched, although theysometimes run for several inches without giving off any laterals (fig. 9).Fissures occur in the soil, extending to a depth of 2 or 3 feet. These have THE PLAINS ASSOCIATION. 47 e\ddently been open cracks and the soil on the sides of them is much darkerin color, having been washed down from the smface. It is in these crevices,where the moisture-content is somewhat higher, that grasses and other plantsbranch and rebranch so profusely. Text Appearing After Image: Fig. 9.—Aristida purpurea. Fig. 10.—Artemisia frigida. MuWenbergia gracilliina.—This grass is also a dominant of the short-grassplains; it is less widely spread and less abundant than Bouteloua gracilis,though in some places it ranks close to the latter. Superficially, it appears likeBulbilis dadyloides, because of its mat-like growth in small areas and the short,curled leaves. Frequently the center of the mat is dead and only theperipheral portions produce flowers. A trench over 4 feet long was dug with, one face cutting through a purestand of this grass to a depth of about 5 feet. Great clusters of roots, onlyabout 0.5 mm. or less in diameter, ran off in all directions from the very sur- 48 THE ECOLOGICAL RELATIONS OF BOOTS.
