Les deux flores sont dominees par Lycophytes mais celle differe proportions toutes autres divisions plantes et se caracterise des populations riches localement abondantes spheno-phytes Plusieurs nouveaux taxons signales pour premiere fois - Miadesmia, Spencerites, Calamo-stachys casheana, C. ludwigii une nouvelle espece Bowmanites. Pteridospermales rares presence leurs graines n'avait pas ete mentionnee avant cette etude. Cinq filicales dont nouvelles especes Anachoropteris un nouveau genre faisceau foliaire courbure adaxiale. genres Zygopteris cf. Clepsydropsis reconnus. En fait ressemble davantage Upper Foot d'Angleterre, montrant Cordaites.A brief survey of the structurally preserved flora (early West-phalian A) is given following study over unsorted specimens from (Liege) collected earlier this century. comparison with Seam Britain, same age, afforded particular emphasis on fern content. Lycopods are dominant in both assemblages but differ those all other major plant and conspicuous by rich locally abundant sphenophyte floras. Many new taxa reported for Belgian including Calamostachys species Pteridosperms rare their seeds have not been before now. Five filicalean to Belgium occur include two genus catenalean foliar strand. The genera recorded first time. In fact bears greater resemblance that seam England which it shares Cordaites.
