6 5 . A N O M O D O N , Hook & Tayl. (Tab. V.)
Calyptra cucullato. Operculum conic-rostratc. Capsule cylindrical, crcct,
long-pcdicellate. Peristome double; tbe exterior 16 subidate-lanccolatc teeth ;
the interior 16 cilia shorter than the teeth, and connected at base by a naiTow
membrane. Inflorescence dicecious. — Stems prostrate, stoloniferous, micro-
phyllous: the branches ascending, simple, 2 - 3 divided or fasciculately ramulose,
with elongated, costate, opaque, granulated leaves ; their areolation minute
and dot-likc. (Name, apopos, in-egular, and obwv, tooth, from a supposed abnormal
construction of tho peristome.)
1. A . v i t i c u l o s i i s , Hook. & Tayl. Branches 2 '- 2 ^ ' high, often geniculate
; leaves secund, larger as they ascend, linear-lanceolate from an oblong-ovatc
base, obtuse, of a thick compact structure, minutely papillose on both surfaces ;
costa pellucid, ceasing near* the apex; annulus double, persistent. — Shaded
rocks, Niagara P alls ; without fruit. (En.)
2. A . a p i c u l i i i u s , Br. & Sch. Very near tho preceding, rather smaller ;
leaves linear-oblong from a cordate-ovate base, apiculate ; cellules with longer
papülæ, those of the hasal margins slightly ciliate ; costa shorter, often forked.
— On old logs, Alleghany Mountains.
3. A . o l> tU S ifô liU S , Br. & Sch. Branches compressed, shorter than in
No. 1, less divided ; leaves 2-rankcd, of a more uniform vddtli throughout, linear-
oblong, very obtuse, the costa shorter; capsule elliptical; inner peristome wanting
or rudimentary; annulus large. — Trunks of trees, near watercourses, in
low grounds. (Tab. V.)
4. A . a t t e s i i i à t u s , Hub. Branches U - 2Mong, fasciculately ramulose;
the ramuli incur\’cd, attenuate ; leaves ovate-lanceolate, somewhat obtuse, sub-
sccund ; annulus none ; peristome well developed, the cilia nearly as long as the
teeth, and with 1 - 2 interposed ciliolæ. — On rocks and roots of trees, near
streams ; common. (Eu.)
5. A . l o n g i f o l i i i s , Hartm. Distinguished from the last by its more
attenuated branches, straightcr and longer acuminate leaves, smaller capsule,
shorter pedicel, and much less complete peristome, — Habitat similai’: said to
be North American by Scliimper. (Eu.)
6. A . Î T o c c ô æ , SulUv. & Lesqx. (Muse. Bor.-Amer.) Branches 1 '- 2 '
long, rather stout, simple or sparingly divided, when dry drcinatc ; leaves lanceolate
from an oblong base, rcflexed on the lower margins, concave below, concave
carinate above, very strongly and irregularly serrate at the point ; cellules
very minute, quadrate-rotund, protuberant (not papillose), aiTangcd in lines;
costa nearly percurrent and flexuous at its upper end. — Toccoa Palls, Georgia,
Lesquereux: with perichætia only. — In the Herbarium of the late Dr. Taylor
are specimens marked “ Neckera Nepalensis, T. T. mss., Nepal,” apparently
the same as those from Toccoa Palls, with imperfect frait like that of No, 4.
7. A .? t r i s t i s , Cesati. M u c h smaller than any of the foregoing ; branches
filiform, rigid, sparingly divided; leaves brittle, usually broken, when moist
squarrose, somewhat ligulatc-acuminate from a broad suljerect amplexicaul base,
* crenulate on the margins by tho large protuherent cellules ; costa indistinct, seldom
extending half-way.—Leskea fragilis, JJooh. ^ Wils. in Drum. Mosses, 2d
coll. No. 101. — Hypnum triste, Mull. Synop. Muse. 2. p. 478.) — Very common
throughout the United States ; on trees, particularly tho Hombcam. Pruit un-
loiown. (Eu.)
66. F É S K E A , Hedw. ; Bryol. Europ. (Tab. V.)
Calyptra cucuUiforai. Operculum conic, acuminate or rostrate. Capsule
oval or cylindrical, pedicellate. Peristome double ; the exterior 16 lanceolate-
subulate teetli ; the interior 16 narrow cilia, as long as the teeth, arising from a
carinate membrane. Annulus persistent. Inflorescence moncecious or dicecious.
Stems prostrate, irregularly or subpinnatcly branched ; leaves of the stem and
branches uniform, ovate-lanceolate, more or less acuminate, mostly costate,
smooth or papillose, with close subrotund or oval areolation. (Named for N. G
Leslce, an early German botanist. )
1. E . p o l y c â r p a , Hedw. Moncecious ; stem 2' long or more, irregularly
branched; branches ascending, ^ '- I 'h i g l i ; leaves ovate-lanccolatc, patent or
secund, recurved on the margins below, strongly costate to near the apex ; capsule
cylindrical, slightly curved; operculum conic, acute; perichætial leaves
striate. — Roots of ti-ces, in wet iflaces. (Eu.)
2. Sb. o b s c i i r a , Hedw. Moncecious ; smaller than No. 1 ; ramification
the same ; leaves ovate or ohlong-ovate, rather obtuse, opaque, the margins below
recurved; costa reaching to the apex ; capsule erect, oblong-elliptical ; operculum
short, conic ; cilia of the inner peristome peiforated. — On trees, within
roach of floods : fruits copiously. (Tab. V.)
3. ï i . m i c r o c a r p a , W. P.-Scli. in litt. Moncecious; stemssubpinnate-
ly branched ; leaves ovate or oval, concave, long aud slenderly acuminate, spreading,
rather lax ; costa reaching nearly to tlie point ; capsule oval-ohlong. — (L.
nervosa. Muse. AUeghan., No. 69.) On roots of trees, in wet woods, near Montgomery,
Alabama. — Very near the Em-opean L. nciwosa, but a more flaccid
plant, its leaves more spreading, not so recurved on the margins, nor so attenuated
at the point.; the costa extending higher up ; capsule not cylindrical ; peristome
smaller and lighter-colored, the interior more imperfect ; and mainly
the inflorescence different.
4. E . r o s ti'ù - ta y Hedw. Dioecious ; branches erect, crowded, fasciculate,
terete ; leaves closely imbricating, ovate-lanceolate, long and slenderly acuminate,
papillose on. both surfaces, the margins broadly recurved below ; costa pellucid,
vanishing below the apex ; capsule oval-oblong ; operculum rostrate. —
Woods, in dense and extensive mats, on the base of trees : frequent. (Eu.)
5. E . Î d î e i i t i c i t l î i t a , Sulliv. Dioecious; branches ascending, crowded,
somewhat compressed; leaves closely imbricating, slightly secund, concave,
ovate, suddenly and rather long acuminate, denticulate, ecostate ; areolation
oval; capsule oblong; opercnlum obliquely rogtrate. (Muse. AUeghan., No.
62.) — Base of trees; not uncommon in the Western States: fruit very rare,
found only in Southern Alleghany specimens. — A small species.
