Bridge and Holmsley Station, Lyndhurst. [Piffard, April, 1882) ! !
This moss was distinguished as a species by Dillenius, and seems entitled
to rank as such by its more delicate texture, and different capsule. Hitherto
it has been regarded as exclusively American, and I have seen no other
record of its occurrence in Europe.

short, branched, radiculose at base. L e a v e s erecto-patent, flexuose, from
a concave ovate-oblong base, suddenly lanceolate-subulate, canaliculate,

the base abrupt at the inner s id e ; annulus broad, lid conic,
subulate rostrate ; teeth confluent a t base on an exserted membrane,
c le ft into two unequal legs, or perforated in the middle line, red,
incurved when dry. Male infl. terminal on a basal branch, b ra cts
small, ovate convolute, acuminate, nearly nerveless.

In a path at base of Schiehallion, near Tummel bridge, Perthshire {Braithwaite and
Lrrombic, 1883) !!
The species of this beautiful genus are remarkable for the long neck to
the capsule which gives the fruit a peculiar club-shaped appearance. Only
a single tuft was found, and that was growing in the centre of a patch of the
rosy red form of Brymn fallens. The genus Bruchia also belongs to this sub-
family.
