an oval shape. (Eu.)

12. P . palaiiitrc, Br. & Sch. Distinguished from the last two species
mainly by its campanulate-conic calyptra 4 - 5-lobed at tho base : inflorescence
as iu No. 11. — Sandy soil. New Jersey, James. Louisiana. (Eu.)

excun-ent costa; the lower leaves much smaller, oblong, acuminate, closely
appressed; capsule ovate; pedicel short; calyptra cuculliform; male flower
gemmiform at the base of the fertile stem. —Pennsylvania, Drummond.
5 6. ÂSTOMUM, Hampe.—-Stems simple or branched, perennial: leaves elongated,
costate, the terminal much larger, -with a loose, hyaline areolation below;
above minute, subquadrate, granulose: calyptra cuculliform: capsule globose or
ovate, more or less rostellate. — (Allied to tho Weisieæ.)
* Hale fower gemmiform, axillary.
14. P. crispiim, Hedw. Stems divided above, bearing several capsules
on each branch ; leaves crisped when dry, shortly cuspidate by the strong ex-
current costa, the lower ovate-lanceolate, the upper linear-lanceolate from an oblong
base, the margins above strongly convolute ; capsule globose, apiculate,
with a more or less obscure operculation. — I t is uncertain if the species is truly
American; bnt specimens (imperfect) from Texas and Indiana appear to belong
to it. (Bn.)
15. P . Sullivântii, Scliimp. Eesembles the last, but has shorter stems,
not so much branched; capsule solitary, shining, bright orange-colored ; calyptra
and spores smaller. — Very common.
16. P. nltidulum, Schimp. Near No. 15, bnt a smaller species, with
a shining, pale chestnut-colored, oval, obliquely rostellate capsule, its pedicel
thrice as long as in tbe last ; calyptra minute, scarcely descending to the obscm'o
line of operculation. — Central Ohio : rare.
*■ * Male fower gemmiform, terminal on the main stem or its branches.
17. P . r , u d o v iC i à n u m , Sulliv. Larger than No. 14 ; leaves very
much the same in every respect ; capsule oblong-oval, obtusely rostellate, usually
2 - 3 in the same perichæth, borne on a branch arising from below the male
flower. — (P. crispum, var. rostcllatum, Sohwoegr. ? Hook. ^ Wils. in Drum. 2d
Coll., No. 10.) — New Orleans, Drummond.
5. B R t lC I I IA , Schwaigr. (Tab. I.)

pedicellate : collum largo. Columella present. Spores numerous, usually
yellow, muriculate. Infiorescence moncecious: male flower gemmifonn, terminal
on a short branch. — Minute terrestrial perennials, with mostly simple stems
and lanceolate-subulate, continuously costate leaves o f a loose oblong areolation
at their base, elsewhere smaller, compact and roundish. (Named after Bruch, a
distinguished bryologist.)
1. B. Ilcxiiosa, SchwiEgr. Stems flcxuoso-ereot, simple; leaves distant,
spreading from an oblong base, long-subulate, channelled, denticulate at tho
apex; capsule obovate-oblong, exserted, abruptly passing into a rather long
slender and flexiious pedicel, covered for half its length by the calyptra. — Var.
NiGiiioANS : Whole plant longer; leaves shorter, appressed; spores larger,
dark brown. — New England to Florida, and westward; the var. on Eaccoon
Mountains, Alabama, Lesquereux, and Cleaveland, Ohio, Prof. Cassds.
2. B. Beyricliiiina, Hampo. Has (according to Schwajgrichen) the
loaves and poiUccl of No. 1, but a much shorter stem, and the calyptra entirely
covering the oblong capsule. — Maryland, near Baltimore, Beyricli. (Not since
detected.)
3. B. brcvipcs, Hook. Stems short; leaves as in No. 1, but erect, overtopping
the globose-oval somewhat pyriform capsule; pedicel short; spores
nearly twice as large as in the first species.-—Louisiana, Dru-mmond.
4. B. t o r e v i f o l i a , Sulliv. Size of No. 3 ; leaves much shorter, broader,
erect, reaching only to the base of the large obovate-oblong and short-pedi-
oellcd capsule; spores as in No. 1. — (Bruchia Vogesiaca, var. 2, Hook Wils.

5. B. Ravenelii, Wils. mss. Almost stemless; leaves lanceolate-subulate
; costa oxcurreiit and with a scabrous ap e x ; capsule globose-pyriform, obtusely
apiculate, slightly exserted, short-pedlcelled; calyptra strongly papillose,

B. Hampeana, C. Mull.)

e . G YM N O STOM IT B I, Hedw. (Tab. I.)
Calyptra cuculliform. Operculum conic-rostrate. Capsule suboval, annulate,

gemmiform. — Katber small, densely ctespitoso species, with linear-lanceolate costate
leaves of a close, opaque, rather quadrate areolation. (Name from yvpvós,
nalced, and crrd/xa, a mouth; no peristome.)
1. G. cui'vii’óstrum, Hedw. Stems fastigiatcly branched ; capsule
