Abstract

SynopsisPsalixochlaena berwickense sp. nov. is described from specimens found in the Cementstone Group of Berwickshire. The incomplete fossils consist of short cylindrical stems, 0·7–1·5 mm diameter, and probably represent portions of one or more branching rhizomes. Attached petioles have not been seen but one detached fragment shows a resemblance in structure to the petioles of P. cylindrica (Williamson) Holden. Branching of the stem is by trifurcate laterals and this distinguishes it from P. cylindrica but bears a superficial resemblance to Rowleya trifurcata Long.
