bordered pits in two (1, 2) tracheids (sample 152, 1942 imitation kraft at 100x enlargement). Note colour mirroring in the two angles (original 45° and 135°). Lenticular, touching pit openings. Ray cell (3), these are rather rare. Checked reaction wood fibre (a). Note the sharp, mechanically untouched fibre endings, this is probably because the fibres are hardly beaten to keep long fibres in this imitation kraft. Sample image rotated 45°, right bottom corner fell outside the original image in rotation and therefore background colour added to the right of the fibre outline [micrographs and z-stack BvV].
