Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . ig. 126-128, G22 - C24). — J5r. Agrostis, Phleum, Poa,Festuca, which are the principal meadow and pasture grasses: Ory-za (Rice), Zea (Maize), Avena (the Oat), Triticum (Wheat), Secale(Rye), Hordeum (Barley), are the chief cereal plants, cultivated fortheir farinaceous seeds. This universally diffused order is one ofthe largest of the vegetable kingdom, and doubtless the most impor-tant ; the floury albumen of the seeds and the nutritious herbageconstituting the chief support of man and the herbivorous unwholesome properties are known in the family except in thegrain of Darnel, which is deleterious. Ergot, or Spurred Rye, isno exception, being a morbid growth, caused by a parasitic stems of grasses frequently contain sugar in considerable quan-tity (especially when they are solid); as in Maize, the sweet varietyof Sorghum vulgare, or Broom-Corn, and in Sugar-Cane (Saccharumofncinarum), which affords the principal supply of this article. 1271 1275 1278 1277 1278.
