. The power of movement in plants. Plants; Botany. 220 CIECUMNUTATION OF STOLONS. IV of damp moss had emitted 2 stolons, 22 and 20 inches in length One of these was supported, so that a length of 4J inches pro- iected in a straight and horizontal line, and the movement of tte apex was traced. The first dot was made at Fig. 89. fU'tS''l". f,G'iO''^ \^ (k 5°30''^ 'lO'3^^ Cotyledon umbilicus: circumnntation of stolon, traced ftom Aug. 25th to 11 27th. Plant illuminated from above. Th' terminal internode was "25 inch in length, the penultimate 2'25,ana the third 3"0 inches in length. Apex of stolon stood at a distance of 5*75 inches from the vertical glass ; but it was not possible to ascertain how much the tracing was magnified, as it was not known how great a length of the internode circumnutated. the terminal portion soon began to bend downwards and con- tinued to do so until noon. Therefore a straight line, very nearly as long as the whole figure here given (Fig. 89), was first traced on the glass; but the upper part of this line has not been copied in the diagram. The curvature occurred in the middle.
