ARENARIA — STELLARIA. 27 I 



amongst the western hills and dales, but although this is the 

 case, it is quite absent from those which lie on the east of our 

 Central Valley. It ascends to the Main Limestone of Mickle 

 Fell and Widdale Fell, and is especially plentiful about the 

 lead-mines of the western dales, as for instance those of 

 Gunnerside Gill, Arkengarthdale, Woodhall and Preston-under- 

 Scar. In Swaledale it descends to Reeth, and with Viola hitea 

 to Applegarth. I have had the Continental A. laricifolia sent 

 to me as A. verna localised from the Yore side at Hutton 

 Conyers. 



Arenaria trinervis L. British type. Native. Area general. 

 Range 0-300. Frequent upon shaded banks, ascending in 

 Teesdale to Mickleton, and in the Yore district to Counterside 

 in Semmerdale. 



Stellaria nemorum L. Scottish type. Native. Montane. 

 Area 9876.432. Range 50-400. Stream-sides and damp 

 woods in the dales, one of the most frequent of the characteris- 

 tically Montane species. In Teesdale it does not ascend above 

 Winch Bridge, but it occurs not only in the main dale, but also 

 in Balderdale and Gretadale, and lower down the Tees as far as 

 Piercebridge, Croft, and Dalton. In Swaledale it grows in 

 Applegarth Woods, and in the Yore district it ascends to the 

 woods of Fossdale and Whitfield Gill, and descends the river to 

 Tanfield. By the Wharfe side it grows near Thorp Arch; in the 

 Central Valley at Kirklington; and on the east in Whitstoncliff 

 and Coxwold Woods, in the dale of the Rye and in several 

 stations in the Howardian tract. Esk Bank in Newbiggin 

 Wood ; Dr. R. Brait/miaite. Its distribution is nearer to that 

 of Trollius than any other species, and in their diffusion the two 

 are only below Myrrhis and Crepis paludosa of the Montane 

 species. 



Stellaria media Vill. British type. Native. Area general. 

 Range 0-650. Shaded and waste places, everywhere common 

 except in the heathery tracts. The highest place in which I 

 have seen it is near a shepherd's hut on the ridge that runs from
