5. Anthoceros sulcatus, Aust.—(Wotothylas Hallii, Aust., MSS., 
1874), n. sp.—Fronde cespitosa erecta basi attenuata flabelliformi 
2—3 lineas longa saturate viridi, margine varie lobata et re- 
panda, involucro circa 4 lin. longo obovato-quadrato scabri- 
usculo, ore repando-dentato, capsula 2—24 lin. longa tenui erecta 
vel curviuscula sulcata fere sessili compresso-quadrangulari, textura 
crassa molli, collumella crassiuscula fibrosa, sporis majusculis fla- 
vidis, elateribus brevibus. :

This species is evidently a connecting link between Notothylas, 
Sulliv., and Anthoceros. ‘ 
Frond apparently hollow, with a few large black tuber-like gem- 
me in its substance ; the apex occasionally descending and bearing 
a roundish tuber, the green granules in the cells larger than in A. or- 
bicularis ; rootlets fascicled, granulose. Involucre from the apex of 
the frond. - Capsules (very numerous) acutely angled when dry, 
narrow, yellow, compressed, striate-angled, of a thick but lax 
texture. Pedicel very short. Spores larger and not. so smooth, 
and elaters paler, otherwise they are much as in A orbicularis. 
In the young state the fronds appear to be prostrate. 
6. Anthoceros (Notothylas) orbicularis.— Carpobolus orbicularis, 
Schweinitz. — Notothylas orbicularis and N. valvata, Sulliv. — 
General appearance of the frond and spores much as in A. levis. — 
Elaters very minute, pale, nearly or quite as broad as long, very 
thin. Capsules more or less curved, 1—2 lines long, erect or de- 
cumbent and wholly included in the involucre or partially exserted 
in the same specimen, marked with a suture on each side, but often 
the valves do not separate spontaneously, of a thin and rather lax 
texture. Antheridia large, usually single immersed in cavities in 
the frond which have the margin slightly elevated. The fertile in- 
volucre remains closed at the apex when the capsule is included ; 
but usually as the latter increases in size, the former becomes irregu- 
larly torn.

r § § Spores black : elaters fuscous. 
7. Anthoceros punctatus, Linn.—Fronds small, depressed, or 
often cespitose and erectish, of a lax texture, more or less glandu- 
lar, and often falsely nerved. Involucre rather Shorter than in 
A. levis, oblong-linear, slightly repand and sometimes scarious at 
the mouth. Capsule about one inch high, black. Spores smallish, 
strongly muriculate, sharply angled. Elaters rather short and 
broad, flattish, geniculate and variously contorted, somewhat 
articulated. - ie 
Var. scariosus, (A, scariosus, Aust. olim ), has the frond and in- 
volucre lamellated, and the latter broadly scarious at the mouth.— 
- Var. Ohionesis. Frond distinctly nerved; apex of the lobes much 
thickened and solid.—Var. Eatoni. Fronds cespitose and erect, 
crowded; involucre narrower, more or less lamellated, parallel to 
and more or less connate with the surface of the frond. 
Canada to the Gulf of Mexico and West to Missouri.—Var. 
1 in S. Car., Ravenel. Var. 2 in Ohio, Lesqguereux, Var. 3 in 
Florida, aton.
