Seeds straw-color, 1/10 inch long (Fig. 17.) Abundant in gardens, lawns and cultivated grounds. June-Oct. Af- ter midsummer in wet seasons one of the worst of lawn weeds often crowding out the blue-grass. When cut or pulled and thrown aside its stems quickly take root from the joints and are soon as luxuriant as before. Dry sandy fields in which melons and other early crops are cultivated are often over-run in late autumn with this foreign grass. The small crab-grass (8: linearis Krock.), differing in having the spikelets shorter, 1/12 inch long, the second scale about as long, the leaves and stems shorter, is also quite com- mon in similar places. Remedies: for lawns, pulling and burning; clean grass seed; for gardens and fields, late hoeing and thorough cul- tivation; burning over in autumn. 3. Panicum cbus-galli L. Barnyard Grass.
