Genus [ Albizzioxylon GREGUSS, 1969 ] (illegitimate)

36) Albizzioxylon hungaricum GREGUSS, 1969 Pl. 2, Fig. 9

M a t e r i a l. Lectotype defined here HNHM-PBO

2008.248.3. (= 3 slides: tr + tg + rd).

37) Albizzioxylon hungaricum GREGUSS, 1969 Pl. 2, Fig. 10

M a t e r i a l. Additional specimen HNHM-PBO

2008.249.3. (= 3 slides: tr + 2*tg).

D e s c r i p t i o n. See Greguss (1969: 50, pl. XXIX, figs

1–9, pl. XXX, figs 10–18, legend p. 137).

N o t e s. The wood is diffuse-porous with vessels solitary or in radial multiples (Pl. 2, Fig. 9) with tyloses (or fragmented gum deposits) and very dense small alternate pits, parenchyma aliform to confluent sometimes crystalliferous and 1–5-seriate homocellular rays (Pl. 2, Fig. 10). Because the holotype A. 142 is missing, we define here the specimen HNHM-PBO 2008.248.3., with all three sections present, as the lectotype. However, it seems that Greguss, when proposing a new fossil genus, did not realise that the generic name Albizzioxylon already existed; the name was proposed already twice before his proposal ( Albizzioxylon RAMANUJAM, 1960 and Albizzioxylon A.A.NIKIT. 1935 ; see Farr and Zijlstra in Index Nominum Genericorum (Plantarum)). As a consequence, Albizzioxylon GREGUSS is a later homonym and must be considered as “illegitimate”.
