Gymnostomum tenue Schrad. Tolerably frequent in Cleve- 

 land on moist sandstone, and usually with fruit, as at Kilton, 

 Roxby, Saltburn, Skelton, Slape Wath, and Upleatham. In 

 the Tees district it occurs at Wycliffe, and on the south side 

 of the river near Gainford, and also at Croft. 



Gymnostomum rupestre Schwg. By the Tees, descending 

 to Whorlton Bridge, Ovington, and Gainford. 



With reference to the Cleveland locality for this plant 

 (Hell Gill, Guisbrough Moor, recorded by the late Mr. W. 

 Mudd in Baker's ' North Yorkshire '), the ironstone has been 

 worked out there some time since, and the station, I believe, 

 consequently destroyed ; in fact, the character of the glen to 

 all appearance has undergone a complete change. 

 *Gymnostomum commutatum Mitt. This species, which in 

 Dr. Braithwaite's Br. Moss-Flora is reduced to a variety of 

 Gyintiosto/niim curvirostnun Ehrh. ( == Barbiila curvirostris 

 var. commiitata (Mitt.) Lindb.) occurs in several localities 

 with almost equal frequency to tlie type. 



In the Tees district it descends on the south side of the 

 river below Gainford, where it grows in great luxuriance and 

 fruits abundantly. Since preparing the present list I have 

 noticed an early record for Gyrnnostonncvi curvirostrum in 

 Hooker's Br. Flora, ii, p. 8 (1S33), by Mr. Backhouse (pro- 

 bably the late W. Backhouse of Darlington), which undoubtedly 

 has reference to the above locality. I have also met with it 

 and in frui-t by Bowlees Beck, at Gibson's Cave, and at Falcon 

 Clints, Teesdale (D.), and by the East Stonesdale Beck, Upper 

 Swaledale. 



Gymnostomum microstomum Hedw. On clay ground at 

 Roxby (C), and Saltburn (C). 



July 1890.
