Araucarioxylon sp. GREGUSS, 1952 Nomenclatural synonymy: 1952 Araucarioxylon sp. GREGUSS, p. 170, pl. 10 fig. 13-15, Úrkút, István shaft, Toarcian. 1967 Araucarioxylon sp. 6 GREGUSS, p. 26, pi. 14 fig. 8-9. Nomenclatural note: although this synonymy is not explicitely given by GREGUSS (1967), fig. 13 and 15 in the first publication (1952) illustrate the second one (1967), just turned up-side-down. Material probably related to this taxon: sample Bx35 (2 slides) in GSR, labelled "Araucarioxylon sp., Úrkút, GREGUSS P."; although marqued with a red 4, these slides cannot be the source for pi. 13 fig. 6-9, illustrating Araucarioxylon sp. 4 in GREGUSS (1967); the wood is amazingly similar to pi. 10 fig. 13-15, illustrating Araucarioxylon sp. in GREGUSS (1952), although we did not found the detail of pictures on the badly preserved slides; Bx35 shows a mixed type radial pitting, with pits half uniseriate half biseriate, and, in some cases only, triseriate; preserved early wood crossfields have not been observed, but late wood shows cross-fields with an unique cupressoid oculipore; Bx35, in itself, is not determinable without further investigations. Araucarioxylon sp. 4 GREGUSS, 1967 Nomenclatural synonymy:. 1967 Araucarioxylon sp.4, GREGUSS, p. 25, pi. 13 fig. 6-9, Úrkút, Upper Liassic. Material attributed to this taxon: nothing reliable found; perhaps S8 in JAS, see below. Genus Baieroxylon GREGUSS, 1961 Baieroxylon lindicianum (KHAN) PHILIPPE, 1995 Nomenclatural synonymy:. 1961 Araucariopitys lindicianum KHAN, p. 114, pi. 45 fig. 5 and 6, pi. 46 fig. 1 and 2, text fig. 3, Lindich, Germany, Lower Liassic. Material possibly related to this species: the set of slides numbered 23/276/x-72/6964, 24/276/X-73/6964 and 25/276/x-74/6964 in HNHM is probably related to this species (however we did not observe the typical tracheid curvature along rays); radial pitting is of mixed type, mostly uniseriate, radial pits forming small or long chains; cross-fields are of araucarioid type;, the wood does not show the characteristics of Simplicioxylon; it is labelled "Eplény, kovasodott fatörzs" [Eplény, silicificd wood]. Genus Callitrixylon HARTIG, 1848 Callitrixylon hungaricum GREGUSS, 1969, nomen nudum Material attributed to this taxon: sample Bx83 (3 slides) in GSR, labelled "Callitrixylon hungaricum Greguss, Pécsbányatelep, jura, András akna, alsó liász". [Callitrixylon hungaricum GREGUSS, Pécsbányatelep, Jurassic, András shaft, Lower Liassic].
