O l J R specimens were obtained on the borders of Dela-
mere Forest in Cheshire; found in dry shady situations,
May, 1831.
It forms extended patches of a pleasant yellowish green
colour; the stems, for the most part, unbranched, those
producing the fructification larger than the rest. Leaves
two-ranked, with dotted reticulation, bi-tridentate (the
gemmiferous ones erose, and very often distinctly bidentate
at the apex of the posterior lobe, so as to correspond with
the descriptions of Schmidel and of Mohr). Fructification
terminal (abortive, so far as we have observed). Peri
