-A .N inhabitant only of the highest of the Grampian
Mountains, as Cairngorum, Ben-y-mac-duich, and others
of that granitic chain, growing upon the summits and
amongst the comminuted rock, where scarcely any other
plant can exist. Dr. Graham met with it upon Fonniven

somewhat creeping and interlacing perennial roots, which
send forth numerous fibres. Leaves short, curved, narrowly
linear, acuminated, channelled and fringed with hairs,
which are, however, very fugacious. The stem, or scape, is
not above four to five inches high, slender and terminated
