描述了产于乌拉圭里维拉省阿罗约塞科早二叠世梅洛组的三种裸子植物：Stiloxylon ferrandoi gen.et sp.nov.，多囊木白刺（Maniero）和Bageopitys sp.这些标本有髓和初生和次生木质部保存。费氏针杆木次生木材的初始部分和髓部具有特殊的特征，这些特征证明了一个新属和新种的建立。其余树干具有已知古冈瓦纳古陆森林的共同特征。
Three gymnosperm woods from the Melo Formation (Lower Permian) at arroyo Seco (Rivera Department, Uruguay) are described: Stiloxylon ferrandoi gen. et sp. nov., Polysolenoxylon sp. cf. P. whitei. (Maniero) and Bageopitys sp. These specimens have the pith and the primary and secondary xylem preserved. Stilaxylon ferrandoi shows peculiar features in the initiaJ portion of the secondary wood and in the pith which justify the creation of a new genus and species. The other stems show common characters of aJready known Pa1aeozoicGondwana woods.
