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

Note: this wood, poorly preserved, was only briefly mentioned by GREGUSS (1969: 102); according to our observations this wood is probably conspecific with Platyspiroxylon sp. 2 GREGUSS 1967. Genus Protelicoxylon PHILIPPE, 1995 Protelicoxylon parenchymatosum (GREGUSS) PHILIPPE, 1995 Nomenclatural synonymy:. 1967 Platyspiroxylon parenchymatosum GREGUSS, p. 47, pi. 92-94, István shaft, Úrkút, Upper Liassic. 1995 Protelicoxylon parenchymatosum (GREGUSS) PHILIPPE, p. 71. Material attributed to this species: sample Bx37 (7 slides) in GSR, labelled "Platyspiroxylon parenchymatosum, P. Greguss, Úrkút, István akna" [Platyspiroxylon parenchymatosum, P. GREGUSS, Úrkút, István shaft] the only cross section, badly preserved, does not fit at all with pi. 42 fig. 1 in GREGUSS (1967); otherwise careful observation of the other slides confirm the attribution of this sample to Protelicoxylon. Genus Platyspiroxylon GREGUSS, 1961 Platyspiroxylon sp. Nomenclatural synonymy: 1967 Platyspiroxylon sp. 2 GREGUSS, p. 50, pi. 95 et 96, Pécsbányatelep, Mecsek, Lower Liassic. Material attributed to this species: we did not find any material reliably related to this name; because of the lack of material we cannot say if this wood belongs to Protelicoxylon. Genus Podocarpoxylon GOTHAN, 1905 ? Podocarpoxylon sp. GREGUSS, 1952 Nomenclatural synonymy: 1952 Podocarpoxylon ? GREGUSS, p. 173, pi. 12 fig, 31-34, Villány, Lower Liassic (Callover Stock). Material attributed to this species: we did not find any material reliably related to this name. Note: curiously this wood is not mentioned in GREGUSS (1967); what is the relationship with GREGUSS' Araucarioxylon sp. 5 ? Genus Prototaxodioxylon VOGELLEHNER, 1968 Prototaxodioxylon sp. Nomenclatural synonymy: 1958 Taxodioxylon sp. GREGUSS & KEDVES, pl. 1 and 2, Pécsbányatelep, Lower Liassic.
