Leaves narrowly linear, apparently in a circle around the joints of the stem but really in two oppo- site sets of 6 to 8 together, with"scale-likc, mod- ified leaves between them. Flowers white, the fruit hanging abruptly downward. The seed is dull black, lens-shaped or round and compressed, ..ith the margin extended into a narrow pale wing. The surface is more or less roughened with sinall, pale-coloured, elongated protuber- ances, like gland-tipped hairs. Hotli the pro- tuberances and the wing are sometimes absent when the seeds occur among comnKT- cial seeds. They are a com- mon impurity in grain grown in the Maritime Provinces Quebec and are occasionally found in timothy and alsike seed. Common Chickweed {Skllaria media (L.) Cvrill.) is an introduced annual occurring in all parts of Canada where the soil is moist and rich; Steins branching, curving upward with a tendency to lie down. Hoots hair-like and exceedingly tough. Leaves ovate. Stems bearing a con- spicuous stripe of articulated hairs down one side. Flowers J inch in diameter, numerous, solitary from the axils of the leaves, in old plants in ter- minal leafy cymes; corolla white.
