A. Carolinianus and A. laciniaius, Sthweinitz. Differs chiefly in 
being larger in all its parts. 
Canada to the Gulf of Mexico and California; the var. in the - 
South and in California. 
2. * Anthoceros caspiticius, De Not. (Syn., Hep. p. 588.)—A. 
tuberosus, Tayl. (Syn. Hep., p. 791.: A. Zorreyi, Aust. MSS.— 
Frond dissected to the base, the divisions narrow and variously © 
lobed, expanded at the apex, very dark green, more or less glandu- 
lar, nerved or nerveless, 2—4 lines long; sending down here and 
there from the nerve underneath, or from its apex, a radiculose 
flagellum, which terminates in a roundish tuber-like turion. In- 
volucre broad, scarcely a line high, broadly sulcate and obtusely 
biangled on the back, minutely punctate; the apex sub-truncate, 
repand-tridentate and narrowly scarious at the mouth. Capsule 
thick, 5—7 lines long, sessile, sulecate or angled, the apex obtuse and 
subtruncate. Spores asin A. levis; elaters longer than in that 
species. Columella thickish, fibrillose. 
The above description is taken from a specimen in Herb. Torrey. 
under the name of “ A. levis, Linn.,” from the Island of Corsica. 
But sterile fronds of the same character have frequently come to 
my notice, mixed with terrestrial mosses from Texas and California.

Fertile plant on the ground, Silverton; sterile on dripping rocks, 
Salem, Oregon, /. Hail. Also in 8wamps, Marvin County, Cali- 
fornia, Bolander. 
Frond albescent or ochraceous below, pale green above, or the 
glandularly thickened portion very dark green, composed of 
several thicknesses of cells; the outer layer smallish, close and 
quadrate, the inner layers eféngated and lax. Involucre terminating 
the frond, and a continuation of the outer layer of cells. Gemmz 
very large, fusiform. Capsule very narrow; the valves remark- 
ably thick. Pedicel very short. 
The California specimens have the fronds prostrate and en- 
-tangied, irregularly dissected, plicate-costate or lamellate; the 
lamellae bearing elliptical tubers underneath.

Oregon, &. Hall. 
Capsule splitting to the mouth of the involucre. Involucre often 
not scarious at the mouth. A small species.
