N e a r Hurstpierpoint [Mitten, 1845) ! !
Mr. Mitten’s name had been engraved on the plate before its identity
with Lindberg’s species had been determined. There is something in the
look of the plant, so different from that of E. serratum, that we think there
can be no doubt of its distinctness, while its small size has caused it to be
overlooked.

This moss is nearer to E . serratum than to the next species, and as the
two sometimes grow together, it is probable that Schimper was thus led
astray, and his remarks at p. 4 of the Synopsis 2 ed. explained; Wilson
evidently did not distinguish it.

becoming reddish-brown by age. L ow e r leaves lanceolate, upper erect,
oblongo-lanc. denticulate toward apex with pro jec tin g cells ; nerve soft,
vanishing at or below apex, cells a t base hexagono-rectangular, above

B y the side of the River Shannon, near Porturana, Galway [Moore,

The Irish plant quite accords with the American in its erecto-patent
leaves with slightly recurved points, and short upper cells, but the specimens
are poor and stunted, and only half the size of the foreign ones.
