Genus Laurinoxylon FELIX, 1883

Genus Laurinoxylon was emended by Dupéron, Dupéron- Laudoueneix, Sakala and De Franceschi (2009)

14) Laurinoxylon daberi GREGUSS, 1969 Pl. 1, Figs 7–9

M a t e r i a l. Holotype HNHM-PBO 2008.158 .4. (= 4 slides: tr + tg + 2*rd).

D e s c r i p t i o n. See Greguss (1969: 34, pl. XVII, figs

1–11, legend p. 134).

N o t e s. As Greguss (1969) noticed, there is a large amount of diffuse axial parenchyma, seen in cross-section as white dots within a brown matrix substance (Pl. 1, Fig. 7), idioblasts are both in rays (Pl. 1, Fig. 9, arrows) and axial parenchyma (Pl. 1, Fig. 8., upper arrow) with the former not as pronounced. Following the new classification by Mantzouka et al. (2016), this species belongs to Laurinoxylon Type 2a. There are also numerous crystals, mainly associated with axial parenchyma (Pl. 1, Fig. 8, lower arrow).

15) Laurinoxylon sussi GREGUSS, 1969 Pl. 1, Fig. 10

M a t e r i a l. Holotype HNHM-PBO 2008.243 .3. (= 3 slides: tr + tg + rd).

D e s c r i p t i o n. See Greguss (1969: 35, pl. XVIII, figs

1–7, legend p. 135).

N o t e s. The wood is diffuse-porous with vessels solitary, in radial multiples or clusters with vasicentric parenchyma and 2–3-seriate heterocellular rays with conspicuous marginal oil/mucilage cells. These idioblasts are very prominent and seem to be located in the margins of rays only (Pl. 1, Fig. 10), therefore this is a Laurinoxylon Type 1 sensu Mantzouka et al. (2016) .
