No other genus of the grass family offers such a numberof species in the Eastern States. Abundant by waysides, in oldfields, and on river banks, Panic-grasses are equally common onsandy soils near the coast. Diverse in form, low species, oftenless than a foot in height, are like miniature bushes; slender onesare lost amid the surrounding taller growth; broad-leaved Panic-grasses, shoulder-high, form dense green thickets by our roadsides;stout species, burned by a hot sun to purple and copper colour,grow in clumps on the beaches, and with long rootstocks bind thewind-blown sands; and a more delicate Panic-grass bearing greatflowering-heads of long, hair-like branches is a common tumble-weed in many states.

It is a comparatively easy matter to refereach Panic-grass to the genus Panicum; thespikelets with their shining, porcelain-likeflowering scales are so characteristic of thegenus that they form an easily distinguishedfeature, but even with the microscope it isoften difficult to determine those of theseveral species that closely resemble oneanother. Cockspur Grass, formerly included inthis genus, which it closely resembles, savein its awn-pointed scales, is common incultivated lands, where its coarse, erectpanicles blossom soon after plant varies greatly, sometimes cloth-ing the flowering-heads in long awns, and again ap-pearing practically awnless. In rich soil the plants are often sixfeet
