figure 82

vessel element, probably birch, in half bleached, pre WWII sulphite pulp (100x) (sample 156) sample rotated 90° clockwise from original image. The vessel has scalariform elements at the left ending (1) and near the right end (1', 1"). The intervessel pitting consists of small, horizontal rows of crowded alternate pits with confluent inner apertures which make the pits look like lines (2). The vertical fibre between 1 and 2 is a typical hardwood libriform (nearly featureless) fibre [micrographs and z-stack BvV].
