Amhlystegium varium (Hedw.) Lindb. Bark of trees, Grandfather Mt.; Blue 

 Ridge near Linville. 



Amblystegium adnatum (Hedw.) Aust. Frequent on bark of trees and on rocks, 



Grandfather Mt.; Grandmother Gap; Wesner Bald; Roan Mt.; 



Swannanoa Mts.; Pardee Point, Tenn. 

 Plagiolhecium Roeseanum (Hpe.) B. & S. Clefts in rocks, Roan Mt., Tenn.; 



White Rock Mt., Tenn.; Cabin Creek (tributary of Dark Ridge 



Creek). 



Plagiolhecium elegans (Hook.) Sull, On ground and among rocks, Roan Mt., 

 Tenn.; White Rock Mt., Tenn.; Double Top Mt.; Grandfather Mt. 

 In the first and fourth localities the species was fruiting nicely, in the 

 second and third fruit was lacking, but abundant propagula were pro- 

 duced. In the characters of its propagula and capsules this species 

 occupies a somewhat isolated position in the genus. I find I have speci- 

 mens of it with propagula from Quarry Run in West Virginia, where I 

 gathered it (mixed with hepatics) in the fall of 1903, but failed to include 

 it in my list. I also have it fruited from the White Mts. of New Hamp- 

 shire. 



Plagiolhecium Miillerianum Schimp. Crevices in rocks, sterile. Roan Mt., Tenn.; 



White Rock Mt., Tenn.; also a station midway between both. The 

 specimen from White Rock Mt. was in a somewhat wetter place and 

 more robust than the others. It produced propagula, which have not 

 to my knowledge been observed hitherto for this species. They are 

 small, growing from the stem clustered in the leaf-axils, where they may 

 be detected through the leaves by careful focusing. They are individ- 

 ually slender filiform-clavate, up to 100 /i long, 7 jj. wide, septate with up 

 to 6 or 7 segments. They correspond closely with the propagula 

 described b}' Correns for P. sylvalicum,^^ but are slightly more slender. 

 I found them in my specimens in the axils of consecutive leaves some 

 8-10 mm. below the growing point of the stem (branch), those lower 

 down having apparently already ripened and been detached, while none 

 had yet developed higher up. Normal archegonial buds occurred much 

 farther down the stems, and the species is dioicous. I found no fruit. 



Semalophyllum Novae- Caesariae (Aust.) E. G. B. Occasional on wet rocks, brook 

 descending from Grandfather Mt. near crossing of Yonahlossee Road; 

 also near upper course of Woodfin Creek in Jones Knob. The latter 

 specimen bears immature capsules (July 28), their period of maturity 

 evidently being considerably later than that of 5. carolinianum, with 

 which the species often grows. Fruit is regarded as very rare in this 

 plant, a single good collection of it having been made in the mountains of 

 Pennsylvania by Wolle and Rau in 1874, from which it was described 

 by Austin.20 In what genus the plant should be included is perhaps 

 still open to question.
