T h i s moss grows on rocks and walls in limestone countries
: it is common in Anglesea and upon the Ormeshead
in North Wales.—The earliest account of it, as a species,
appears in the above-cited work of Dawson Turner, Esq.
It was formerly confounded with O. cupulatum*, from
which it is easily distinguished by its narrow and conspicuously
elevated capsules.
A handsome species growing in small round dense tufts.
Stems above half an inch long; leaves of a dark purplish
green with colourless points, their nerve vanishing above;
teeth of the peristome white, erect when dry, converging
when moist, never recurved.
