LIST OF MOSSES. 67 



ginate. Color light green. Stems 2-4 lines long, filiform, creep- 

 ing, densely raclienlose. Leaves scarcely wider than the stem, 

 somewhat distant, subdistichons, erecto-patent, broadly and ob- 

 tusely complicate-concave, under pressure broadly cuneate-triradi- 

 ate, distinctly serrate-denticulate, |-bifid; sinus broad and obtusish 

 or sometimes acutish, lobes triangular-ovate, acute; areolation mi- 

 nute, for the most part quadrate, with the interstices narrow and 

 hyaline. Involucral leaves 3, ^-connate, 2-3(?) lobed, spinulose- 

 dentate. Perianth terminal on a longish, club-shaped branch, pli- 

 cate to the base; apex obtusely triangular, white, deeply laciniate, 

 the lobes sub-linear, truncate, their apex minutely denticulate."

J. LESCURIANA. (n. S.) 



On the ground in open woods, Orange county, C. F. Austin. 



" This is a larger species than the last with longer and more en- 

 tangled sterile stems and subulate, sub-squarrose amphigastria. 

 Fertile stems more clavate, erect, and crowded. Leaves more im- 

 bricated and the lobes more ovate, the lower not serrate. Involu- 

 cral leaves numerous and crowded into roseate or capitate heads 

 which are at first terminal, but at length dorsal, the inner ones 

 highly connate, scarious and eroded-denticulate on the margin above. 

 Perianth broadly oval, nearly white, strongly and acutely plicate, 

 and even in the young state deeply laciniate-lobed; the mouth denticu- 

 late. The leaves towards the apex of the fertile stems are less 

 deeply bifid than the lower ones and often 2-5 papillate-dentate at 

 the subtruncate apex of the lobes." Austin MSS. 



J. bicrenata, Lindbg. 



Ground in bleak open woods; Ilelderberg mountains, Shawangunk 

 mountains, C. F. Austin. 



Color varying from pale green to reddish-brown. Stems short, 

 thick, densely radiculose; leaves orbicular or subquadrate, very 

 concave, closely imbricating, rather thick and firm, emarginate-2- 

 toothed, with a lunate sinus and acute teeth; involucral leaves 2-3- 

 toothed, serrate; perianth terminal, ovate, plicate, the mouth ciliate- 

 denticulate, connivent.

Old logs. Sand Lake. Not common. 



J. barb at A, Schreb. 



Rocks and thin soil covering rocks in mountainous localities. Fre- 

 quent and variable. Rarely fruits. 

 Var. attenuata, Mart. 



Rocks and ground; High Peak, Catskill mountains. Fertile. 



Stems more slender than in the typical form, erect; lower leaves 

 eroded-denticulate at the apex; upper leaves uniformly 3-toothed; 

 amphigastria wanting.
