Abstract

ABSTRACT -An analysis of internode lengths in the Hippuris stem is represented by a four phase growth curve, The two parameters which infl~ence this pattern of internode lengths are the number of cells per internode and the length of the individual cells within the internode. In the ontogeny of the Hippuris stem cell length and cell number influence internode length in the distal portion of the stem while in the basal portion of the stem cell number is the major factor affecting internode length. The pattern of stem growth in Hippuris differs from that of Elodea in that the cell number in Elodea reaches a maximum before cell length, and the major factor influencing internode length is cell length.
