Chrosperma rnusGcetoxicv/m^ commonly known as " stagger grass," " fly poison," " crow poison," or " fall poison," shown in figures 1 and 2, belongs to the lily family. It grows from a coated bulb, and reaches a height of from 1| to 4 feet. The leaves are narrow and grasslike, those of the stem being few and short. The stem is much longer than the leaves and bears a dense raceme of flowers, which turn greenish with age. The fruit is red. The plant is found in sandy woods from Long Island to Florida and west as far as Arkansas. It is said to grow at an altitude of 4,000 feet in Virginia. The plant was first brought to the attention of this department by Mr. F. L. Huggins, of Wilmington, N. C, in March, 1911. He sent specimens of the plant and reported that the people of that neigh- borhood Imew it as "stagger grass," and said that it was fatal to sheep in 24 hours. He said also that many cattle had been sick and that some had died from its effects. The matter was deemed of suffi- cient importance to make an investigation of the locality where the losses had occurred. The locality is a typical plains region of eastern 60420°—18.
