themselves for a considerable distance from the main stem ; some of these roots 

 were about the size of an ordinary walking-stick. Cases of remarkable roots 

 are fauiiliar to oljscrvers. 



An I'ltisfia bicolor happened to have its leaves injured l)y an accident, wliich 

 cut the niidril) and a jiortion of leaf on Ijoth sides of it; after a certain time, 

 the wound healed, the part next the base of the loaf remainint,^ the 

 same thickness as before the injury, while the edge of the outer portion 

 gradually thickened, and developed a small bud close to the midrib, 

 Fig. 2, from which a number of minute fibrous roots issued, and 

 eventually a stem and leaves, as represented in the sketch. As the 

 plant increased, the old leaf gradually became exhausted, and perished 

 altogether as soon as the young leaves gained the ascendency and de- 

 prived it of the scanty means that had previously supported it. Simi- 

 lar instances are familiar, not the least 

 interesting of which is that of a broken 

 celery-leaf, which sent out roots from 

 the lowermost of its wounded edges. 



In general, roots have no buds, and 

 are, therefore, incapable of multiplying 

 the plant to which they belong. But 

 it constantly occurs. In some species, 

 that they have the power of forming 

 what are called adventitious buds; and, 

 in such cases, they may be employed 

 for purposes of propagation. Tliere is 

 no rule by which the power of a plant 

 to generate such buds can be judged 

 of; experiment is, therefore, nccessarj', 

 in all cases to determine the point. 

 Exceptions are found in the Moutan peony, in the plum-tree, or the Pyrus 

 (Cydonia) japonica, which may be increased with great facility by small bits of 

 the roots being inserted in a shady border, and covered with a hand-glass ; but in 

 none of them does the power reside in the same degree as in the Japan Ane- 

 mone. If a root be taken after flowering, it will be found to resemble brown 

 cord, divided into a great number of ramifications, as represented in the cut. 

 Upon its surface will be perceived a multitude of white conical projections, some- 

 times growing singly, sometimes in clusters, and occasionally producing scales 

 upon their sides. A magnified view of these bodies is shown in Fig. 3, a. 

 They are young buds, every one of which, if cut from the parent, will grow and 

 form a young plant in a few weeks, every fragment of the plant being pro- 

 ductive. 



It is certain that vitality is stronger in the roots than in any other part of 

 Live roots have been found in land many years after the trunks to
