T h i s I gathered in the neighbourhood of Matlock bath,
Derbyshire, in 1790; of the precise spot I am not certain.
The plant has hitherto either not been observed in any other
part of Britain, or has been confounded with H. proliferum,
from which it is very distinct. The stem and branches are
not half so large as in that species, nor do they grow in the
same proliferous manner. The latter are only doubly pinnated.
The leaves are finely serrated, and have all, for the most part,
3 nerves, of which the middle one is very conspicuous. The
leaves of the sheaths are long and taper, very inconspicuously
serrated towards their points. The fruit-stalks are always solitary,
reddish, shorter than those of the last-mentioned, but
longer in proportion to the branches. Capsule incurved, cylindrical,
brown. Lid short and conical, with a minute
point, a little curved. By the shape of the lid these 2 species
are essentially distinguished.
