F ound frequently on mountainous barren heathy dry
places, being in the greatest perfection in the moist weather of
the winter or early spring. By drought it becomes dry, with
its leaves curled inward, and its whole substance very brittle.
The stems form tufts, and are at first more or less cupshaped,
but they soon become branched or proliferous, and are
clothed with leaves, at least till stripped by time. The leaves
are flat, cartilaginous, variously lobed and cut, sometimes
pinnatifid; green above, white beneath: the radical ones
upright. Indeed the young plants at first are mere leaves,
bearing small cups with tubercles all over their upper surface;
but the perfect state is as above described, in which the
imperfectly formed cups branch out into short stalks tipped
with small round dark-brown tubercles, accompanied by small
leaves.
