The longer cells, occurring in groupswithin the cleft, are straight and narrow, resembling bast fibers, whilethe medium and shorter cells, occurring both on the surface and in thecleft, are broader and more irregular in outline, vermiform and club-shaped forms predominating, although triangular and various fantasticshapes are not uncommon. Great variations in the thickness of thewalls and the size and number of the pores are also noticeable. 2. Parenchyma Cells (Fig. T)T,t„ Q; Fig. 337, p), more or less obliter-ated, form the re
