as the teeth, but they are so described by Boulay and by Husnot, 

 and are sometimes equally long in Wilson's Muse. Brit. No. 220. 

 Stableria gracilis was discovered by Wilson in Cheshire, Eng- 

 land, in 1833. Since then, three or four English stations and two 

 in Finistere, France, have been added. It is another interesting 

 link in the chain of relationship between the bryophyte flora of 

 California and that of Europe." 



Stableria gracilis (Wils.) Lindb., var. Californica M. A. 

 Howe. "Leaves linear-lanceolate, acuminate, broader than in 

 the typical form and without subulate points; antheridia sur- 

 rounded by a few small bracts, on a short gemmiform branch. 

 Near Eureka. The leaves of this variety are often strikingly 

 different from those of the type, but it grows mingled with the 

 ordinary form and plants bearing leaves of a transitional char- 

 acter are found. The specimens which we have identified with 

 the type, so far as observed, are paroicous, but var. Californica 

 appears always to be autoicous. Braithwaite describes Stableria 

 gracilis as exhibiting both these methods of bearing the an- 

 theridia. " 



Stableria is a genus closely related to Leptobryiim pyri- 

 forme (L.) Wils., and for the benefit of our readers we insert 

 Mr. Dixon's description of the species: "Stems densely tufted, 

 slender, hardly branched, about X-K in. high, rarely taller, 

 bright green, silky. Leaves fiexuose, when dry somewhat 

 curled, very narrow, linear-setaceous, the upper longest {1-1)4 

 lines); margin plane, entire or obsoletely denticulate above, 

 nerve vanishing at apex, narrow, rather indistinct above, areola- 

 tion narrowly linear-rhomboid, at base wider, hexagonal-rect- 

 angular, hyaline. Seta short, less than yi in. high, pale, very 

 slender; capsule suberect, narrowly clavate, with a slender taper- 

 ing neck, thin-walled; lid acutely pointed. Peristome teeth in- 

 curved when dry, inserted below the mouth of the capsule; outer 

 teeth narrow, distant; inner peristome a very short basal mem- 

 brane with sixteen slender processes without intermediate cilia. 

 Paroicous; antheridia in the axils of the comal leaves. "

Brachythecium lamprochryseum gigan'TEUM n. var. Stems 

 much stouter, secondary stems with fewer branches; stem leaves 

 distant, longer, 3-3.5 mm. long, very strongly plicate; extreme alar 

 cells inflated. Capsule ovoid; operculum conic-rostrate; annulus 

 large, persistent; segments as long as teeth, from a very broad ba- 

 sal membrane; cilia 2 or 3 well developed, nodose; spores matur- 

 ing in winter. Atku Id., Behring Sea. (U. S. S. Albatross, No. 

 44. June 10, 1894.) 



Brachythecium rivulare cataractarum Sauter. Fl.Herzogth- 

 Salzburg. 3: 60. 1870. Floating, dark green to golden green, 

 brown underneath; secondary stems much elongated, simple or 

 sparingly branched; branches short, directed forward at an acute 

 angle; leaves much more closely imbricated, especially at the tips 

 of the branches. On timbers of old dam, Staley's Creek, Virginia.
