Herbs, rarely woody or arborescent, with (mostly) hollow, jointed culms; with leaves alternate, distychous. on tubular sheaths split down to the nodes, and a licfula (stipules) of membranous texture where the leaf joins the sheath. Flowers in little .spikelets of 1 or several, with glumes distychously arranged, and collected into spikes,, racemes or panicles. Glumes, the lower pair of scales in the spikelet, alter- nate, enclosing the fls. Pales (pake) the outer pair of scales of each particular flower, unequal. Scales (perianth) usually 2 or 3, minute, hypogynous, distinct or united. Stamens 1â6, commonly 3, anthers versatile, of 2 distinct cells. Ovary simple witii 1 ascending ovule, 2 styles and 2 feathery stigmas. Fruit a caryopsis. Em- bryo lateral, at the base of the farinaceous albumen. Genera 300, species about 8S00, universally diffused throughout the world, having no ether limits than those that bound vegetation in general. But the species and their characters are widely different in different climes. In temperate zones the grasses clothe a large portion of the earth's surface with a compact, soft, green, carpet-like turf; but in tropical regions this beautiful grassy turf disappears and the grasses become larger, more isolated like other plants, fewer in the number of individuals, with broader leaves and more showy flowers. Properties.âThis family doubtless contributes more to the sustenance of man and beast than nil others combined. Its sweet and nutritious properties reside both in the farinaceous albumen "â f the seed and in the herbage. No poisonous or even suspicious herb is found among them, with the single exception of Lolium temulentum. The poisonous and medicinal Ergot or Spurred Rye is only a parasitic fungus, and
