Genus Meliaceoxylon GREGUSS, 1969

51) Meliaceoxylon matrense GREGUSS, 1969 Pl. 2, Figs 15, 16

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

2008.188.3. (= 3 slides: tr + tg + tg/rd).

D e s c r i p t i o n. See Greguss (1969: 89, pl. LXXX, figs 1–9, legend p. 149).

N o t e s. This is a diffuse-porous wood with vessels in radial multiples, intercellular canals of traumatic origin, closely spaced in tangential bands (Pl. 2, Fig. 15), axial parenchyma diffuse to diffuse-in-aggregates, and paratracheal and 2–3-seriate heterocellular rays. We also observed an unusual and relatively big structure that we interpret as an isolated axial canal, probably also of traumatic origin (Pl. 2, Fig. 16). Concerning the (in)validity of the fossil genus Meliaceoxylon GREGUSS (see Farr and Zijlstra in Index Nominum Genericorum), there are two type specimens indicated by Greguss (1969: 90), i.e. Nos 201 and 202. Our reinvestigation discovered that specimen No. 201 was missing, so we define here the specimen HNHM-PBO 2008.188 .3. (= A. 202) as the lectotype.
