Buxbamnia aphylla\^. {2^^). Only two specimens collected. Growing 

 on earth among other mosses and lichens on "The Dome," near Dawson, at 

 4,000 ft. elevation. This seems to be the most northern point it has yet been 

 collected in America. 



Brachythecium edentatum n. sp. 



Low and loosely csespitose with lax, spreading leaves. Stems procum- 

 bent, with few, short and irregular branches. Stem leaves ij^ mm. long by 

 3/5 mm. wide, not decurrent, pale, ovate-lanceolate, shortly acuminate, con- 

 cave, scarcel)'- or not plicate, margin entire, flat ; costa rather faint, extend- 

 ing a little above the middle, rarely shorter and forked, with sometimes 

 small clusters of radicles on lower side at its base. Branch leaves smaller, 

 entire. Leaf-cells above the base very narrow, the median .004 to .005 mm. 

 wide and .04 to .05 mm. long. Alar cells abruptly enlarged, hyaline, often 

 forming distinct, inflated, convex clusters. Perichaetial leaves but little 

 longer than stem leaves, gradually acuminate, half costate, very entire. 

 Dioicous. Pedicel smooth, up to 2>^ cm. high. Capsule when moist about 

 two and one-half times longer than broad, curved, much contracted under 

 the mouth when dry. Annulus narrow. Height of conical lid scarcely 

 equalling its basal diameter. Segments of inner peristome solid, with two 

 or three smooth cilia between. 



This is one of the smaller species, in size perhaps nearest j-efiexum. It 

 seems quite distinct from all others in the very entire leaves, with narrow 

 cells above and inflated clusters m the angles. It differs from B. Beringia- 

 7iiiin Card. & Ther. in having the majority of leaf -cells little more than half 

 as wide, in the different alar cells and in the low. creeping stems with lax, 

 spreading leaves (374). Gold Run Cr.. on wet earth, June 6
