Louisiana : Pointe-a-la-Hache, on ground in half-shaded 

 places, growing with the typical form (A. B. Lang/o/s). 

 New Jersey: Atco (H. A. Green). 



Webera Cardoti Ren. — Loosely cespitose, pale green 

 or yellowish. Stems simple, erect, slender, rigid and brit- 

 tle. Leaves small, erect, imbricate, oblong-lanceolate, de- 

 current, strongly revolute on the borders, obtuse or subob- 

 tuse, rarely subacute, generally sinuate-denticulate at apex. 

 1-1.5 mm. long, .35-.50 mm. broad ; costa very broad, green, 

 percurrent or vanishing very near the apex, widening below 

 and occupying one-third of leaf base. Areolation loose, cells 

 truncate or subattenuate, 2-3 times longer than broad. Ped- 

 icel reddish, flexuous, often geniculate at base, 10-15 mm. 

 long. Capsule oblong-subpyriform, symmetric, erect, yel- 

 lowish or brownish, tapering to an attenuate neck, 2-2.5 mm. 

 lon g« -35--75 mm. broad ; lid conic. Peristome small, pale 

 yellow 1 , pellucid, very minutely papillose ; teeth triangular- 

 lanceolate, long acuminate, provided with 15-25 lamellae ; 

 inner peristome more or less perfect, with split segments and 

 cilia, or reduced to a variously raised and lacerate mem- 

 brane. Annulus of 2-3 rows of cells, 

 smaller; flowers gemmiform, terminal. 



Oregon: Mt

Polytrichum sexa insular e Fl. (L. F. Henderson). Already 

 kindly communicated in 1882 by Mr. L. Lesquereux but 

 likely from the same collector, who sent to us recently a 

 large and very interesting collection of Pacific coast mosses, 

 including several new species, which we are now describing 

 and drawing for the Botani* vl Gazette. 



The W Cavdnti is nllied to Pohlia erecta Lindb., from 



our 



Norway, but this has the leaves plane on the borders, the 

 costa less broad, vanishing far below the apex, the peristome 

 reddish, etc. W. commutaia Sch. is also somewhat related to 



species, but is at first sight distinguishable from it by its 

 drooping and broader capsule, the convex apiculate lid and 

 the larger peristome. 



Bryum Sawyeri.— Loosely or densely cespitose, green 

 or brownish. Stems short, 10-15 mm. long, radiculose be- 

 low, branching by several innovations and more or less copi- 

 ously provided in the upper part with brown, thick simple, 

 articulate and very caducous filaments, arising from the axiis 

 of the leaves. Leaves regularly distant or the upper tutted.
