The studied material is represented by 13 samples of silicified wood collected from the Holbav locality, on Maiului brook. All the studied samples are fragments of trunk or thick-branch fragments, with centimetric to decimetric size, dark color and, by hand lens or even naked eye, the regular fibrous structure without vessels is visible, evidence of a conifer wood. The specimens, with the following field numbers: 1071, 1072, 1073, 1075, 1076, 1080, 1081, 1101, 1103, 1108, 1110, 1112, 1113b belong to “Grădinaru Collection” and are stored at the

The late-wood is represented by 2-3 rows of thick-walled and radially flattened cells (radial diameter of 5-10 μm). Intercellular spaces are present. The interradial bundles have 1-10 radial regular rows of tracheids. Density is of 992- 1518 tracheids per mm

The pits have round to hexagonal borders, diameters of 18-22 μm, and are variably flattened when contiguous (d/D=0.65-0.88), bearing round or tilted elliptic apertures of 7.5-10 / 2-3 μm. Sometimes crassulae or helical thickenings can appear.

– in cross-section appear usually uniseriate and linear. In tangential section, the rays show 1-20(-25) cells in height (i.e. 30-570(-650) μm). The taller uniseriate rays have biseriations, which give sometimes a fusiform aspect. The ray-cells have polygonal rounded to oval section, marginal spaces and sometimes have dark content. The ray density is of 5-11 rays per horizontal millimeter. The rays appear homogeneous, with cells all procumbent, of 20-30 μm tall, relatively thick walled, of 4-5(7) μm the double wall. Within the marginal rows, but not only, the ray cells are taller, of 30-40 μm, and have slightly corrugated outer walls. The cross-fields are of araucarioid
