A NATIVE of mountainous turfy heaths. We have gathered
it on the Pentland hills, Edinburgh, as well as on
Cromford moor near Matlock, and are obliged to Mr. Lyell
for these specimens from the New Forest, Hants. It bears
fruit at various seasons, but not frequently.
The leaves are more dilated and sinuated than in some of its
allies, greenish above, white underneath. Stalks about an
inch high at most, unbranched, cylindrical, hollow, scaly or
mealy, terminating in very slender cups of scarcely their own
diameter, whose rims are generally simple and entire, occasionally
divided or toothed, bordered with a series of beautiful
little uniform bright-scarlet tubercles, which turn brown
with age.
