Milkweed. — The common milkweed may be known by its stout, unbranched stem (2 to 3 feet high) ; its thick, oblong, opposite leaves (4 to 8 inches long) ; and its milky juice. The dull purple flowers have a rich odor and grow in umbels from the axils of the leaves. Their structure is very complicated, and the stigma can be reached and pollinated by insects only with great diffi- culty, so that from the many flowers only an occasional pod is formed. For the seeds in this pod nature has provided a generous supply of long silk

For the seeds in this pod nature has provided a generous supply of long silken hairs, able to carry them long distances on the wings of the wind. 36. Wild Flax. — A plant 12 inches or more in height, with blue flowers and narrow leaves, looking much like the culti- vated flax. This wild flax, however, is per- ennial. It is ornamental and is often found in the flower garden. 37. Yellow Flax. — Similar to the preced- ing, but a smaller plant, and with yellow flowers; easily recognized as a flax. 38. Prairie Rose. — This is a beautiful rose growing on a homely shrub, the stems being crooked and very prickly and only a foot or two high. The root is killed with great difficulty, and the plant is therefore Wild Flax.
