Genus Liquidambaroxylon FELIX, 1884

32) Liquidambaroxylon weylandi GREGUSS, 1969 Pl. 2, Fig. 3

M a t e r i a l. Holotype HNHM-PBO 2008.241 .4. (= 4 slides: 2*tr + tg + rd).

D e s c r i p t i o n. See Greguss (1969: 42, pl. XXIV, figs

1–9, legend p. 136).

N o t e s. There are opposite vessel-ray pits, 20–30 bars in scalariform perforation plates (Pl. 2, Fig. 3, left), and numerous bubble-like inclusions (granules) in rays, seen in radial section (Pl. 2, Fig. 3, arrows).

33) Liquidambaroxylon kraeuselii GREGUSS, 1969 Pl. 2, Fig. 4

M a t e r i a l. Holotype HNHM-PBO 2008.202 .3. (= 3 slides: tr + tg + rd).

D e s c r i p t i o n. See Greguss (1969: 44, pl. XXVI, figs

1–9, legend p. 136).

N o t e s. Similarly to Greguss (1969), we observed the scalariform perforation plates with only about 10 bars (which is a rather low number for Liquidambar ; for comparison see Sakala and Privé-Gill 2004), and heterocellular rays with long uniseriate extremities. Moreover, there are rich crystalliferous contents in chambered axial parenchyma (Pl. 2, Fig. 4, arrow) and possibly also disjunctive ray parenchyma cell walls.

34) Liquidambaroxylon maegdefraui GREGUSS, 1969 Pl. 2, Figs 5, 6

M a t e r i a l. Holotype HNHM-PBO 2008.239 .3. (= 3 slides: tr + tg + rd).

D e s c r i p t i o n. See Greguss (1969: 45, pl. XXVII, figs 1–9, legend p. 137).

N o t e s. This is a well-preserved wood with an excellent radial section showing scalariform perforation plates with almost 30 bars (Pl. 2, Fig. 5, right arrow, Pl. 2, Fig. 6). The rays are uniseriate to biseriate (Pl. 2, Fig. 5, left arrow), so different from the other species of Liquidambaroxylon . The original inventory number (No. 61.932.1.) quoted by Greguss (1969: 46) was not observed on the slides, but we consider the specimen as an original holotype .
