. Plant life [microform]. Botany; Botanique. Hi i i ;i ' 192 TBB 8T0BT OF TBS PLAMTB. material, interposed between the corky dead cells of the integument and the woody dead cells of the interior. This living Uyer extends over stem, twigs, and branches: it forms the binding and connecting portion of the entire plant community ; it links together in one united whole the living material of the leaves and shoots with the living material of the roots and rootlets. It is thus the stem, above all, that gives to the complex plant colony of foliago and flowers whatever organic unity and individuality it ever possesses. All situations, however, are not alike. Just as here this sort of leaf succeeds, and there that, so in stems and branches, here this form does best, and there again the other. The shape of the stem and branches, in fact, is the shape of the entire plant colony; and it is arranged to suit, on the average of instances, the convenience of all its componenii members. Much depends on the shape of the leaves; much on the condi- tions of wind or calm, shade or sunshine. Some plants are annuals. These require no large and permanent stem; they spring from the seed each year, like peas, or wheat, or poppies; they make a stem and leaves; they produce their flowers; they set, and ripen, and scatter their seed; and then they wither away and are done with for ever. Hundreds of sucn plants occur in our fields and gardens. Even these annuals, however, differ greatly in the amount of their stem and branches. Some are quite low, humble, and succulent, like.
