Xylotype Nechranice 1

Pl. 5, Fig. 6–9

M a t e r i a l: Nechranice: 112/06.

D e s c r i p t i o n. Wood is diffuse-porous; growth rings are poorly observed.

Vessels: Rarely solitary (24%), more frequently in radial multiples of 2–7 and in clusters; solitary pores circular to angular in outline. Tangential diameter 42–96–149 µm, radial diameter 84–149 µm; pore density 27 per square mm.

Rays: Homocellular, 1–2 cells (14–56 µm) wide, 3–28 cells (21–196 µm) high, composed of procumbent cells; density 4–7 rays per tg mm. Biseriate rays have short uniseriate extremities, some have uniseriate portions among two biseriate bodies.

Axial parenchyma: Scanty paratracheal.

Fibres: Not observed.

D i s c u s s i o n. Extremely poor preservation of the material does not allow any closer systematical attribution. However, we can say that this taxon is different from all the previously described ones and we propose to designate it as “ Xylotype Nechranice 1”.
