H ab. Near the summits o f various mountains in Scotland. I t has been collected
by D r H o o k e r and myself, and I believe also by other botanists,
on several elevated ranges in Breadalbane, especially on Ben Lawers,
Craig Challioch, and Mealgreadha; Mr D r ü m m o n d has also recently
communicated it from the Mountains o f Clova, where it seems to be
produced sparingly.
tStems h a lf an inch to one inch in height, branched, green above, reddish-
brown below, growing in a dense manner in the crevices of rocks.
Leaves oblong, acute, entire, somewhat waved a t th e margin, the nerve
either reaching to the summit or passing beyond it into a hair-like subdiaphanous
point. When moist, the leaves are erecto-patent; when
dry, erect, appressed, involute a t the margin, not much twisted, and rath
e r rigid in appearance. Fruitstalk h a lf an inch or more in length.
Capsule cylindrical, oblong, straight, vèry distinctly marked with somewhat
prominent, longitudinal (not spiral) striæ. L id about h a lf as long
as the capsule. Peristome o f 16 rath e r narrow teeth, pale at the points,
re d below, more or less persistent. Calyptra cylindrical-campanulate,
mostly with th e base irregular, and as i f slightly torn, and exhibiting
the remains o f such processes or appendages as occur in F. ciliata.
