beyond the bracts, oblong-oval, acute, obtusely trigonous, composed
of a single layer of cells, about 60 near the middle, near the base
composed of two layers, mouth constricted, 6-dentate, teeth small.
Calyptra mitriform, rostellate, thickened near the base. Pistillidia
lew, 4, 5, small. Capsule oval, reddish-brown. Spores brown,

Found on the Continent and in North America.
O b s .—When fertile this is at once distinguished from others
by its postical inflorescence, with the exception of Harpanthus
Elotowii, which is a larger plant, with more orbiculate leaves,
smaller sinus, and cells of a different shape.
I t differs from any of the forms of Jung, bantriensis, for which
it might be mistaken when barren, in its paler green colour and
larger arcuate stipules.
