Calyptra conic-mitriform, shortly lobed at the base. Opercnlum conic-rostratc.
Capsule oval, horizontal, pedicellate. Peristome double; the exterior 16 Miiear-
lanceolate and closely aificulated teeth; the interior 16 carinate lanceolate-subulate
cilia, arising from a broad plicate membrane. Inflorescence monoecious. —
Large and handsome species, with an in-cgulai’ sparse ramification, broad and
flat stems and branches, and complánate shining membranaceous leaves, of a
very loose areolation, formed by large oval-hexagonal hyaline ceUules. — (Named
after Sir JVm. J. Hooker.) — (Tab. V. contains a figme of the type of the genus,
Ilookcria lucens, with ecostate and obtuse leaves, which has not been detected
on tliis continent, except in Oregon.)
1. Iff. a c u t i f o l i a ^ Hook.? Grows on tlie ground, beneath dripping
rocks, Southern Ohio, and Alleghany Mountains, in Pennsylvania and North
Carolina. — Our specimens, as far as we are able to detemiinc, (being without
fruit,) agree well with II. acutifolia. Hook., an East-Iudian species, which appears
to dificr from H. lucens, Smith, only in its acute leaves.

Calyptra dimidiate, somewhat twisted, long, embracing the top of the pedicel.
Operculum conic-rostellate. Capsule oval-oblong or cylindrical, crcct, long-pedicelled.
Peristome double; the exterior 16 linear-lanceolate, closely articulated
teeth ; the interior 16 linear-lanceolate, carinate, lacunose cilia, connected at the
base by a very narrow membrane. ColilmcUa emergent. Inflorescence dioecious.
— Large and striking Mosses, of a trce-like aspect. — (Name from Kkipá-
K io v , a little ladder, from the appearance of the cilia of the inner peristome.)
1. C . A m C ï i c à î î l im , Brid. Main stems rhizoma-like, suhtcrrancous ;
primaiy branches erect (2 ^ '-3 ' liigh), below simple, furnished with small and
appressed scale-Iikc leaves, above fasciculately branched ; leaves ovatc-lanccolate,
auriculate at the base, concave, plicate, costate nearly to the apex, serrate above,
with a minute elliptical areolation ; capsule cylindrical. — On the ground, or on
very much decayed logs, in moist shady woods. (Tab. V.) (Eu.)
C . DEXDROiDES, Web. & Mohr., (common in Europe,) with a shorter and

Calyptra dimidiate, small, fugacious. Operculum between homisphcrical-
apiculatc and conic-rostratc. Capsule ovate or cylindrical, more or less unequal,
usually arcuato-cernuous. Peristome double; the exterior 16 linear-lanceolate
articulate teeth, marked on the back by a medial line, and cristate on
the inner free by projecting cross-bars; the interior 16 carinate processes or
ciha, arising from a plicate membrane, with 1 - 3 ciliolæ between each pair.
Inflorescence monoecious, dioecious, or polygamous.'—A genus, as generally
received, embracing a very large number of species, which, presenting in habit
and structure great diversity, may for the most part be combined info natural
groups, many of them seemingly of generic value. ( Y ttvov, an ancient Greek
name for some sort of Moss.)
§ 1. THXJÎDIÜM, Bryol. Europ. — profusely villous, prostrate or ascmd-
ing, 1 - 8-pinnate ; branchlets mostly short, slender, crowded : stem-lmves broadly
ovate, long-acuminate ; those o f the branchlets much smaller, ovate, and ovate-lanceolate
; all papillose ; areolation dot-like, granulated, opaque ; costa subcontmuous,
translucent : capsule ohlong-oval, or cylindrical, more or less cemuous : operculum
hemispherical-apiculate or conic-rosti'ote.
1. Iff. t a m a T Î s c i n u m , Hedw. Dioecious ; stems prostrate ; ramification
closely 3-pinnate ; stem-leaves with reflexed and crenulate-denticulate margins ;
branch-leaves ovatc-lanccolate; perichætial leaves fringed on the margin ; operculum
conic-rostrate.— On the ground and old logs. — A large and very common
species. (Eu.)
2. Ï I . < l e l î c â t i i l u m , L. Dioecious ; veiy much like the preceding,
but its ramification only 2-pinnate ; operculum conic, acuminate, not rostrate ;
perichætial leaves not fringed. — On the ground, in dry places.'—'Mountains of
Pennsylvania ; rare. (Eu.)
3. Iff. m l a i i i t i i l u m , Hedw. Monoecious; smaller than the preceding,
with a simply pinnate ramification ; capsule horizontal, oval, nearly regular ;
operculum large, convex-conic, with a long slender beak. — On decayed logs, in
woods; not rare. (Eu.)
4. Iff. p y g m æ i im , Bryol. Europ. (Muse. Bor.-Amer. No. 275.) Much
smaller than the last ; ramification 2-pinnate ; leaves more suddenly acuminated ;
pcrichætial leaves elongated, with a more lax reticulation. — Shaded ravines, on
limestone rocks, Central Ohio ; growing with H. minutissimum. — Among the
smallest of the Hypna.
5. ÏS . s c i t s i s n , Beauv. Monoecious ; intermediate in size between No.
2 and 3 ; ramification pinnate ; easily recognized by its cylindrical, nearly regular,
and erect capsule, with a conical, shortly rosfrate operculum. — Hilly districts,
on the base of trees, particularly the Bccch.
6. ffff. g r i l c i l e , Br. & Sch. Monoecious ; size and ramification as in the
