See. flowering in the latter part of fummer, but rarely.
It forms denfe tufts of ramifying ftems about an inch high,
whofe branches are alternate, {lender, uniform, cylindrical,
clothed on every fide with clofely imbricated leaves, which
are fmall, ovate, fharply pointed, entire, without nerves, green
with a bright filvery glofs when frefh, brown when dry; the

is unequally torn or toothed, and from whence rifes a fmall
{lender ftalk, bearing the little brown capfule.—When dried
the branches fometimes afiume a fquare form, from the leaves
