cells are lodged the pale buff, solitary, roundish and nearly
sessile anthers. Calyx double, the outer one deeply laci-
niated, with lamellae attached to the principal segments;
inner calyx much larger, oblong, slightly compressed, the
mouth scarcely contracted and obscurely toothed. Calyp-
tra about half as long as the inner calyx, never exserted in
our specimens. Capsule clavate-oblong, deep chocolate
colour, dull on the surface, separating into only 2 valves,
unless forcibly divided, when a 4-valved structure becomes
apparent, as in other species. Seeds at first clustered,
four together, adhering to the sides of the spiral filaments ;
at length loose, globular, dark reddish brown, slightly granulated.
Spiral filaments composed of a double helix in a
pellucid tube tapering at each end, soon falling after expansion
of the capsule. In an early stage the inner calyx
is extremely short, not equalling the length of the pistilla.
The specimens figured in Dr. Hooker’s Monograph have
evidently been drawn up among moss, and the perigonial
scales are in consequence much less copious and of a paler
colour than in ours, but we can discern no essential difference,
We are also persuaded that the distinctions pointed
out in that admirable work, between this species and J . Ly-
ellii, will prove to be well founded, though we have not
yet had an opportunity of comparing authentic specimens :
the ramification of the frond in J.Lyellii appears to be quite
different; the strong fibrous nerve is also remarkable, and
the exserted calyptra is a striking peculiarity ; but our specimens
prove that no dependence can be placed on the perigonial
scales in distinguishing these closely allied species.
