form, white, delicate, faintly reticulated. Outer peristome
of 10, equal, dark red teeth : inner, of a membrane cut into
16, equal, rather broad, cilia.
The greater number of species of the genus Hookeria are
tropical, or inhabit the warmer parts of the East as well
as the West Indies, Africa, and the islands of the South
Seas. In Europe we have only two species; the well known
H . lucens, which extends very far north, and the subject of
the present description, of which, however, only one station
is known, namely in the South of Ireland, in a wood in the
vicinity of Cork, where it grows near a spring whose temperature
is considerably higher than that of the surrounding
atmosphere. Mr. Drummond was its discoverer.
The specimens here figured were communicated by N. J.
Winch, Esq., having been gathered by W. Wilson, Esq.,
in his late botanical excursion to the South of Ireland.
