Trees are woody plants rising by a trunk to a greater height than shrubs. 67. Herbs are divided, according to their character and duration, into Aiitiudliif ^itnnil((l-<, and I'^Tinnials. 68. Annuals grow from the seed, blossom, and die all in the same season. In this climate they generally spi'ing from the seed in spring, and «lie in the autmnn, (pr sooner if they have done blossoming and have ripened their seed. Oats, liarley, Mustard, and the common Morning-Ulory (Fig. 4) are familiar annuals, l^lants of this kind hnvenf'fiinft roots, /'.<'., composed of long and slender threads or liljres. Either the whole i-oot is a cluster of such libres, as in Indian Corn (Fig. 48), Jiarley (Fig. 56), and all such plants ; or when there is a main or tap root, as in Mustard, the Morning-Glory, See, this branches off into slen- der fibres. It is these fibres, and the slender root-hairs which are Ifound on them, that mainly absorb moisture and other things from I the soil; and the more nunu^rous they are, the more the plant can I absorb by its roots. As fast as nourishment is received and pre- i| pared by the roots and leaves, it is expended in new growth, par- Ifticularly in new stems or branches and new leaves, and finally in f flowers, fruit, and seed. The latter require a great
