After a few additional days the ill-defined zone of cells becomes distinct, and although it does not extend across the whole width of the petiole, and although the cells are of a green colour from contain- ing chlorophyll, yet they certainly constitute a pulvinus, which, as we shall presently see, acts as one. These small cells were arranged in longitudinal rows, and varied from 4= to 7 in number; and the cells themselves varied in length in different [arts of the.
