The present paper represents the second part of the palaeoxylotomical study on the “Grădinaru Collection” that is housed by the National Museum of Geology, Bucharest. By the study of a new material collected from the Getic domain of the South Carpathians, Romania, the following taxa were identified and discussed in detail: Protocupressinoxylon dragastanii, Protojuniperoxylon holbavicum (sp. nov.), Brachyoxylon holbavicum, B. cristianicum, Palaeoginkgoxylon sp., Bucklandia sp. A, and Bucklandia sp. B. All the studied specimens suggest to a tropical Early Jurassic petrified forest. Thus, the new data have not only palaeobotanical importance, but they also contribute to the palaeobiogeographic, palaeoecologic and palaeoclimatologic knowledge of the Mesophytic

This paper reports the palaeoxylotomical study of petrified conifer remains from Velitzelos collection, orig-inating from some fossiliferous sites of Greece, especially from the Aegean area (Evros, Limnos, Lesbos), aged of late Oligocene to early Miocene. Ten species were identified: Cupressinoxylon akdikii, Juniperoxylon acarcae, Tetraclinoxylon velitzelosii, Taxodioxylon gypsaceum, Taxodioxylon taxodii, Glyptostroboxylon rudolphii, Glyptostroboxylon tenerum, Pinuxylon pineoides, Pinuxylon halepensoides and Pinuxylon sp. aff. Pinus canariensis. These new identifications add new elements to the forest assemblages of the Oligocene - Miocene Greek flora, useful for understanding the evolution of the Cenozoic palaeovegetation and palaeoclimate in the Aegean area.

A collection of petrified wood, hosted by the Natural Sciences Section of the Museum “Vasile Pârvan” from Bârlad, was submitted to a palaeoxylotomical study. The samples come from the central part of Moldova, Northward of Bârlad, and were collected from Simila gravel-quarry, from fluvial-deltaic sediments of Maeotian age, most probably representing reworked elements from a Sarmatian formation which occurs in situ more Northward, in Soleşti-Avereşti-Huşi area. Previous palaeobotanical studies made in that region outlined an interesting Late Miocene Flora on the Moldavian Platform, and the palaeoxylotomical studies confirmed in that area the presence of forests with conifers, elms, oaks and poplars. The results of the present study show the following taxa identified taxa: Glyptostroboxylon cf. rudolphii Dolezych et Van der Burgh, Ulmoxylon scabroides Greguss, Quercoxylon bavaricum Selmeier, Quercoxylon intermedium Petrescu et Velitzelos, Populoxylon tremuloides Iamandei et Iamandei, and Prunoidoxylon multiporosum Dupéron.
