The ZIG-ZAG CLOVER, COW or MARL-GRASS (T. Medium), a native of Europe and Asia, now naturalized in the eastern half of the United States and Canada, may scarcely be told from the common red clover, except by its crooked, angular stems - often provokingly straight - by its unspotted leaves, and the short peduncle in which its heads are elevated above the calyx. Farmers here are beginning to learn the value of the beautiful CRIMSON, CARNATION or ITALIAN CLOVER or NAPOLEONS (T. incarnatum), and happily there are many fields and waste places in the East already harboring the brilliant runaways. The narrow heads may be two and a half inches long. A meadow of this fodder plant makes one envious of the very cattle that may spend the summer day wading through acres of its deep bright bloom. GOAT'S RUE; CAT-GUT; HOARY PEA or WILD SWEET PEA (Cracca Virginiana; Tephrosia Virginiana of Gray) Pea family Flowers - In terminal cluster, each 1/2 in. long or over, butterfly-shaped, consisting of greenish, cream-yellow standard, purplish-rose wings, and curved keel of greenish yellow tinged with rose; petals clawed; 10 stamens (9 and 1); calyx 5-toothed. Stem: Hoary, with white, silky hairs, rather woody, 1 to 2 feet high. Leaves: Compounded of 7 to 25 oblong leaflets. Root: Long, fibrous, tough. Fruit: A hoary, narrow pod, to 2 in. long. Preferred Habitat - Dry, sandy soil, edges of pine woods. Flowering Season - June-July. Distribution - Southern New England, westward to Minnesota, south to Florida, Louisiana, and Mexico. Flowers far less showy and attractive than this denizen of sandy wastelands, a cousin of the wisteria vine and the locust tree, have been introduced to American gardens. Striking its long fibrous root deep into the dry soil, the plant spreads in thrifty clumps through heat and drought - and so tough are its fibers they might almost be used for violin strings. As in the case of the lupine, the partridge pea and certain others akin to it, the leaves of the hoary pea "go to sleep" at night, but after a manner of their own, i.e., by lying along the stem and turning on their own bases. In similar situations from New York south and southwestward, the MILK PEA (Galactia regularis; G. glabella of Gray) lies prostrate along the ground, the matted, usually branched stems sending up at regular intervals a raceme of rose-purple flowers in July and August from the axil of the trefoliate leaf.
