Fam. 7. DICRANACEÆ.
Plants varying in size from minute to very ta ll, innovating d ichotomously.
L ea ve s broadly lan ceolate to subulate, often sheathing a t
base, nerved, smooth or ra rely papillose ; areolation quadrate or
oblong and chlorophyllose above, e longated rectangular and pellucid at
base, with or without larger inflated or coloured basal angular cells.
C a lyp tra large, cuculla te or irregular. Capsule erect or cernuous, in a
few low forms cleistocarpous ; lid large, usually rós ta te ; peristome of
16 teeth, confluent at base, c le ft h a lf w a y or sometimes to base into two
lanceolate or subulate legs, trab e cu la te , minutely striate on outer
surface, very ra rely entire, v ery rarely wanting.— Inhabiting the ground,
rocks or rarely trunks o f trees.
This immense family embracing probably 600 species is distributed
throughout the world, and at all altitudes. O f the six subfamilies under
which the European species are arranged, one— Trematodonteæ— is not found
with us, though represented on the continent by three species of Trmnatodon,
and three of the cleistocarpous genus Bruchia, one of which B . (Sporkdera)
palustris may possibly occur here. Th e larger species of Dicranum have great
uniformity in habit and foliation, and require careful examination to determine
correctly ; many of them are beautiful mosses with tall stems and glossy
lanceolate, often falcato-secund leaves, and our D. Bonjeani and majus, the
Scandinavian D. elatmn and southern D. Blumei, setosmi and Billardieri, are
among the noblest of the genus.
Th e presence of larger pellucid or coloured cells at the basal angles of the
leaf is an important character in separating Dicranum from Dicranella, and
the term basal angular cells is used in preference to alar cells, employed by
C. Mueller, as being more definite and correct, for all the cells composing the
wing of the leaf are alar cells. The other European genera not represented
in Britain, are Atractylocarpus M i t t . (Merceya S c h im p .J— Aongstroemia B r . S c h .
— Trematodon M ic h x .— Bruchia N e s t l e e .— Bryoxiphimn M i t t . — Cheilothela
L i n d b .— Oreoweissia S c h im p .
Sulf. I . D ITR ICH EÆ . Plants very small or tall, slender; leaves
lanceolate-subulate, without enlarged basal angular cells. Peristome of i 5
subulate teeth, with a median line, or cleft into 32 cilia, approximate in pairs ;
a few species cleistocarpous.

(Bryol. Univ. i, 747 (1826). )
Plants very small, slender, branched, innovating below the apex.
L e a v e s ovato-lanceolate, nerved, with la x hexagono-rhomboid a reo la tion.
Capsule sessile in an imperfect v aginula, cleistocarpous, globose,
leptodermous, formed o f a single stratum o f cells, without a spore-sac
