AbstractIn New Brunswick, the Pictou group, which underlies an area of about 9,500 square miles, is the only Carboniferous group that contains workable coal. Most of the plant remains described are from the Minto and Clifton formations, and from shales above a thin coal seam at Beersville. Those from the two formations are approximately the same age, and are equivalent to that of a lower part of the Linopteris obliqua zone of Sydney coalfield. Plants from Beersville and from a few other localities in the southeastern part of the province are younger and correspond in age to an uppermost part of the Linopteris obliqua zone, or less probably to a basal part of the Ptychocarpus unitus zone. Of fifty-eight specifically named species described, fifty-three are assigned to species previously described, and forty-two of these occur also in the Sydney coalfield; four of them, viz., Bellopteris corsini (Radforth and Walton), Pecopteridium sullivanti (Lesquereux), Saportaea dispar (Dawson), and Cordaitanthus rhabdocarpi (Dawson), are given new combinations. Four new species are described, viz., Sphenopteris barbalata, Sphenopteris hirticula, Pecopteris ( Asterotheca) acadica, and Gymnostrobus wilsoni, of which Pecopteris acadica occurs also in the Sydney coalfield.
