Philippe, M. ; Barbacka, M.: A reappraisal of the Jurassic woods from Hungary

Material attributed to this species : ?A - sample Bx 533 in GSR, labelled "leg. L. Sikabonyi, Úrkút"; no slides were found that could be associated with this sample; however the label fits with KEDVES' indications (1955: 3). B - sample S2 (4 slides) in JAS, labelled "Úrkút, szenesedett fatörzs, Vadász E. ajándéka, István akna" [Úrkút, wood from VADÁSZ E., István shaft, coalified material]; the detail of pl. 21 fig. 2 (GREGUSS 1967) has been found on slides; radial pits are commonly biseriate and alternate, sometimes even triseriate; rays never have the Simplicioxylon structure; material is coalified and thus may correspond to the coalified sample given by VADÁSZ to ANDREÁNSZKY in 1948, or to the one VADÁSZ gave to GREGUSS (GREGUSS 1952: 166). ? C - set of slides numbered 12, 13, 14, 15 and 16 in HNHM, labelled "Araucarioxylon, Úrkút, leg Szőts"; as far as can be said from the badly preserved slides, this wood may be included there; this material is coalified and thus may also correspond to the coalified samples given by VADÁSZ to ANDREÁNSZKY in 1948 and to GREGUSS; however no mention is made of SZŐTS in the original papers (ANDREÁNSZKY 1949, GREGUSS 1952). D - sample S3 (4 slides) in JAS, labelled "Úrkút, 1948, mangánérces agyag" [Úrkút 1948, manganese clay]; detail of pi. 9 fig. 2 in GREGUSS (1967), illustrating Araucarioxylon resiniferum, has been found on slides; the xylologic characteristics fit with those of Agathoxylon agathiforme; otherwise the slides are not at Eötvös Loránd University in Budapest as GREGUSS said (1967: 22), but in József Attila University in Szeged. E - sample S4 (3 slides) in JAS, labelled "Úrkút, István akna, leg Vadász 1950" [Úrkút, István shaft, leg VADÁSZ 1950]; the detail of pl. 8 fig. 2 in GREGUSS (1967), illustrating Agathoxylon mecsekense, has been found on slides; amazingly GREGUSS gave the epithet mecsekense "since it was found in the Mecsek". He further wrote that the sample originated from the István shaft in Úrkút, a locality actually in the Bakony Mountains; the slides being labelled "Úrkút", we consider that the original locality is thus Úrkút, and not the Mecsek Mountains. F - S7, set of 3 slides in JAS, labelled "Cseh N., 1962, Úrkút, III akna, északi vágat, szenesedett fatörzs, apti agyag" [Cseh N., 1962, Úrkút, III shaft, northern gallery, coalified trunk, Aptian clay (now Albian clay)]; the detail of pi. 32 fig. 2, illustrating Torreyoxylon boureaui in GREGUSS (1967), has been found on slides; this partly silicified sample is probably reworked from Liassic layers. Agathoxylon sp. 1 Nomenclatural synonymy: 1967 Araucarioxylon sp. 7 GREGUSS, p. 27, pi. 15 fig. 1-9, Vasas, Upper Dogger. Material attributed to this taxon: sample Bx82 (11 slides) in GSR, labelled "Greguss, felső dogger or liász, Pécs, Vasas I, Araucarioxylon sp. 7, Kőszénöszlet" [GREGUSS, Upper Dogger or Liassic, Pécs, Vasas I, Araucarioxylon sp. 7, coal measure]; the preservation is poor, but the wood can confidently be refered to Agathoxylon; contrary to what GREGUSS (1967) stated, radial pits can locally be biseriate (see also GREGUSS 1967, pi. 15, fig. 5); all the slide labels mention the age as Lower Jurassic, thus the age of the sample is controversial.
