M R . G. DON alone appears to have gathered this species,
which he first observed in 1795, on the highest mountains of
Clova, Angusshire. He has subsequently met with the same
on many of the loftiest Highland hills; so that it is justly appropriated
to the commemoration of himself and his country.
No fructification has been detected.
The stems grow erect in dense tufts, and are from one to three
inches long, the thickness of horse-hair, wavy, rigid, brittle
when dry, brown, scarcely ever throwing out any branches,
leafy from top to bottom. Leaves of a dull brownish or tawny
green, inserted horizontally in two rows, but curved to one side,
crowded, uniform, oblong-ovate, about a line in length, concave
; their edges entire, often incurved; the point obtuse, with
an acute notch.—This plant is very distinct from every other
British Jungermannia.
