cylindric, 3-3.5 mm. long, 4-5 : 1, somewhat arcuate, horizontal to 

 suberect ; operculum long-conic, subrostellate ; annulus large ; 

 segments nearly as long as the teeth ; cilia one or two, nearly as 

 long as the segments, strongly nodose ; spores minutely roughened, 

 17-19 u, maturing in autumn or winter. 



Type locality, mountains of New England. 



On earth and stones in wet shady places, especially in moun- 

 tain regions. Northeastern United States and eastern Canada ;

Easily distinguished by its rostellate capsule, short papillose 

 leaf-cells and twisted leaf apices. The species varies considerably 

 in length of the acumination of leaves so that var. Delamarci Ren. 

 & Card. Fl. Miq. 50, does not seem worthy of special mention, 

 although I have not seen specimens of that form. 



Limpricht's description (/. c.) and several specimens of Bryhnia 

 scabrida (Lindb.) Kaurin from Norway have been carefully com- 

 pared with B. Novae-Angliae and the two are not to be distin- 

 guished. The measurements of the leaves given by Limpricht for 

 B. scabrida are larger than those given for B. Novac-Angliae in 

 my Rev. N. Am. Isotheciaceae and Brachythecia, but a further in- 

 vestigation has shown that the maximum measurements there given 

 were too small. There is no difficulty in finding American plants 

 with as large leaves as the European. Specimens of B. Novae- 

 Angliae have been sent to Prof. Kaurin and were examined by 

 him and submitted to his friend, E. Ryan. Both agree with me 

 that the American and the European plant are the same. The 

 Newfoundland plant referred by Kindberg to B. scabrida is cer- 

 tainly B. Novae- Angliae. 



Mrs. Britton in 1889 first noted the great resemblance between 



B. scabrida and B. Novac-Angliae and sent specimens to Prof 



Kaur 



vision of Brachytkecium. In 1897 Dr. Best's attention was called 

 to the matter by the Newfoundland plant named B. scabrida by
