 flat at the borders ; the outer basal cells faintly chlorophyllose, nar- 

 rowly marginate.

 Island, May 20th, 188t. (Macoun.) 



(227.) B. papillinervis, C. M. & Kindb. MS. (n. sp.) 



Allied to B. ruralis. Upper leaves subacute, leaf-base narrowly 

 margined, with pale-yellow cells ; calyptra very much prolonged below 

 the capsule.

 at Eevelstoke, Columbia Eiver, B.C., 1890 ; on rocks west side of 

 Lower Arrow Lake, Columbia Eiver, B.C. (Macoun.) 



(228.) B. leptotricha, C. M. & Kindb. (n. sp.) 



Differs from Barbula ruralis, principally in the shorter leaves, 

 emarginate at the apex, with a fine and nearly smooth hair-point ; the 

 basal cells hyaline. 



On limestone rocks. Point "Wilkins, Lake Winnipegoosis, Manitoba, 

 July 16th, 1881. (Macoun.) 



(229.) B. (Syntrichia?) rotundo-emarginata, C. M. &Kindb. 



(n. sp.) 



Dioecious. Plants loosely tufted, brown, about 1 cm. high. Stem 

 beset with emarcid leaves or naked below. Comal leaves close, patent 

 when moist, scarcely curved, papillose, short obeordate, not sheathing ; 

 margins slightly or not recurved ; cells subquadrate, the inner basal 

 greater and hyaline ; costa red and thick, faintly rough at back, 

 excurrent into a long, hyaline, or at the base reddish, more or less 

 denticulate hair-point. 



This species belongs either to the section Syntrichia or to Eubarbula 

 (Ganeifolioe) ; the leaves are larger than in Barbula carnifolia.
