scribo: „All authentic specimen from 51r. D ickson (agreeing well with his dc- -
scription, though not with the figure) in 51r. T urner’s Herbarium, enables.us

Dr. SCHWAEGRICHEN, Supplies the means of identifying that moss, the ligiires and
descriptions of which in Schwaegr. Suppl. and in Bryol. germ, are inaccurate.“
