very long and hygrosoopical, connivent when moistened, reflexed

T. T E N U IS , Schimp. (Syn. ed. 2, 360), long considered hy European authors
as a variety of the last, has been sent to Schimper from Greenland.
It differs in being more slender, softer, and more loosely cespitose; leaves
broadly spatulate, shortly acuminate, very thin, and more loosely areolate;
capsule smaller, with a broad orifice; pedicel more slender; columella long-
exserted; teeth dark purple; spores nearly twice larger and hyaline.
2. T. sp la ch n o id e s, Hook. Gregarious or irregularly and
loosely cespitose; stems soft, much divided: leaves flaccid,
longer than in tlie preceding species, long-spatulate, lanceolate-
acuminate, nneqnally and coarsely dentate to the middle : male
buds of three leaves, terminal on long distantly foliate branch-
Icts: capsule erect or subcernuous, elliptical-oblong, soft, greenish
yellow when filled, contracted to a narrow cylindrical neck,
the whole reduced to half its length when d ry ; pedicel very
long, pale re d ; lid conical, variable in length, capping the persistent
columella; teeth very long, thong-shaped, purple and
cleft their whole length with age, involute under the orifice of
the capsule when moist, reflexed, sinnous and twisted when
dry, flexible when breathed upon. —■ Quart. Journ. Sci. ii.
