The only kind, a slender little plant, from six inches to a foot tall, usually with smooth leaves, with small stipules. The tiny flowers are white, pink, or greenish-yellow, with a bristly calyx, and the corolla usually has four petals, but sometimes five or three; the stigmas two. The fruit is covered with hooked bristles. This grows in mountain woods, as far east as Wyoming. There are many kinds of Galium, widely distributed; sometimes shrubs; stems square; leaves in whorls, without stipules; flowers small, usually perfect, in clusters; calyx usually with no border; corolla wheel-shaped, four-lobed; stamens four, short; ovary two-lobed; styles two, short, with round-top stigmas; fruit dry or fleshy, consisting of two similar, rounded parts, each with one seed. The common name, Bed-straw, comes from a tradition that the manger of the Infant Christ was filled with these plants. Other names are Goose-grass and Cleavers.
