Barnyard Grass. This is a stout, coai-se plant, common in manured soil, it is from one to four feet in lieight, and branches from tlie base. The s|iikelets form dense spikes, and these are crowiled in ii dense iianiclo which is rough with stiff liairs. The structure of the siiikelets is much the same as in Old-Witch Grass, but the jialet of the neutral flower is pointe<I with a rough awn or bristle. 8. Foxtail. In the common Foxtail the inflorescence is apparently a dense, bristly, cylindrical sjiike. In reality, however, it is a spiked panicle, the spikelets bsing much the same as in Barnyard Orass, but their jtrdicels are prolonged Ijcyond thein into awn-like bristles. In this plant the bristles are in clusters end are barbed , TItc spikrn arc fairiii/-;/(l/oir in colour. THE PLANT-BODY GENERALLY, And the Functions of its Parts. The higher iilaius, such as phanerogams, are found to bo made up of four distinct kinds of memljcrs, as follows ; A.—Ruor: embracing the ordinary subterranean forms as previously described, and certain aerial forms, togetlier with those of parasitic plants which feed upon other living organisms. The root differs from the stem in several important respects: (a) It is ripped with a mass of hardened cells consti- tutiug the roof-rnp (Fig. 24:j, ,/
