SOME COMMON WEEDS Paul J. White WEED has been defined as a plant for which we have not yet found a use. Perhaps it would be more correct to define a weed as a plant which is growing out of its proper place. Timothy is a useful plant but you do not want it intruding into your flower garden. We are fond of dande- lion greens and often grow the plant for that purpose, but if we have to spend hours and even days pulling them out of the lawn we are in- clined to call them weeds. In this leaflet we want to study a few of the most common weeds found near our homes. Let us begin with the wild mustard. It may be recognized by its bright yellow flowers which begin to appear when the plant is but a few inches in height. It has rather large, juicy leaves with large veins on the under side. The stem is rough with short, stiff bristles. At the base of the leaf and where the branches come out, yovL will find a reddish spot. The plant is often found in gardens and is common in cultivated crops. It is especially troublesome in oat fields. Foxtail resembles millet. It grows in newly seeded lawns, in fields and in the garden. The lower part of the stem is reddish brown. This color is also found on the under side of the leaves and on the soft bristles of the head. Look for a few soft hairs about one-fourth of an inch long near the base of the leaves. (See Fig. 17). Crab-grass has long finger-like branches on which the seeds are borne. (Fig. 20.) It appears in July and is a troublesome weed until late in summer. A single seed will send up several stems which root at the joints. The leaves are wa\y margined on one edge and are covered with soft downy hairs both on the upper and lower Fig 12.—Common daisy.
