Trematodon longtcollis Michx. On ground, recent railroad cutting between Lin- 



ville and Linville Gap; also near Beetree Creek. 

 Ditrichum lineare (Sw.) Lindb. On ground, in considerable quantities about 



summit region of Roan Mt., Tenn. 

 Ditrichum pallidum (Schreb.) Hpe. On ground, White Rock Mt,, Tenn. 

 Dicranodontium asperulum (Mitt.) Broth. Vertical rocks at high altitudes, 



without fruit, Jones Knob; Grandfather Mt. 

 Dicranum montanum Hedw. A poorly developed sterile specimen from a log, 



Blue Ridge below Grandmother Gap. Williams^^ gives the southern 



limit as West Virginia. 

 Weisia viridula var. ausiralis Aust. (= W. longiseia L. & J.) On earth, bank of 



Beetree Creek. 



Amphidium Mougeotii (B. & S.) Schimp. Vertical rocks, not seen in fruit, 

 Woodfin Falls; White Rock Mt., Tenn.; Grandfather Mt. 



Tnchostomum cylindricum (Bruch) CM. On vertical rocks, usually at high 

 altitudes, persistently without fruit, Jones Knob from summit region 

 down to Woodfin Falls. 



Torlella tortuosa (L.) Limpr. Vertical rocks, summit region of Grandfather Mt. 



Evans & Nichols give its southern range as "northern United States." 



Tortella caespiiosa (Schwaegr.) Limpr. Ground, not uncommon at lower alti- 

 tudes, vicinity of Asheville and Beetree Creek. 



Tortula caroliniana Andrews.^'' A sterile species with propagula growing on the 

 bark of trees, Swannanoa; also North Fork of Swannanoa River and 

 Grandmother Gap. Two other sterile specimens of Toriula are of in- 

 terest: one from the historic Shelter Rock about a mile and a half south 

 of Roan Mt. Station, Tenn., the other from an exposed rock near Swan- 

 nanoa. Both were growing with or near Fabronia and are probably of 

 southern rather than northern affinities. I am unable to identify either 

 with any described species and they are apparently distinct from each 

 other. The material is however totally inadequate to be branded with 

 dubious new species names, and I recommend further collection and 

 study of southern Tortulas. 



Grimmia apocarpa (L.) Hedw. Rock near Balsam; also Roan Mt. Evans and 

 Nichols give its range "from the northern U. S." The specimen from 

 the summit region of Roan Mt. is noteworthy in having large papillae 

 on the leaves, particularly those of the perichaetial region. 



Grimmia Doniana Sm. Rock, Roan Mt. A remarkable extension of range, as it 

 was not hitherto known south of the White Mts. of New Hampshire. It 

 was found growing only on a single rock in the summit region near an 

 old trail leading down the North Carolina side. The plants were a little 

 more robust in all parts than those growing in the summit region of ths 

 White Mts., corresponding well with the forma elongata of Loeske'e 



North American Flora, XV, 120. 1913.
