474 Mr. Hardy on the Moss Flora of the Eastern Borders. 



When old and withered, the capsules are stout and broad like 

 those of a Bryum ; the lid sometimes persistent. 



Under T. subtdata I have alluded to a supposed preference it 

 had to the sea-side ; but on examining those examples, I find 

 the leaves have quite a difiPerent structure from those of that 

 species. I have not yet got perfect capsules ; a few autumnal 

 ones did not survive the conveyance home ; and the rising crop 

 while I write, in March, is only partially swelled out ; and 

 from the places where it grows being within the reach of stream- 

 sides and the drifting foam, it is doubtful if they attain maturity. 

 At least in past seasons they have always been blasted. This 

 moss has been seen by Mr. Wilson, and it is new to him. 



Hah. On moist clayey soil close on the borders of the sea, at 

 Siccar point, and a little further to the north beneath high shady 

 rocks ; the soil being of red sandstone origin, while the rock 

 beneath is greywacke. Its accompaniments are Desmatodon ner- 

 vosus, Pottia crinita, Trichostomum Jlavo-virescens, and T. crispu- 

 lum, — species peculiarly littoral. 



16. T. RiGiDA, SchuUz. IN. On a clay wall near Belford. — 

 W. B. B. 



17. T. AMBiGUA, Br. and Sch. B. On clayey soil on the sea- 

 banks behind St. Helen's Church. The Greenheugh T. aloides 

 belongs here ; the capsule which furnishes the distinction ripens 

 in February and March. 



Trichostomum crispulum, T. mutahile, and T. Jtavo-virescens. N. 

 On the sea-coast at Dunstanborough Castle. — W. B. B. 



The foregoing list contains the occasional investigations of my 

 friends and myself among the Border Mosses for the three by- 

 past years. The localities are entered in the order of the date at 

 which the species occurred ; and the several districts marked 

 B., N., E., represent Berwickshire, Northumberland (inclusive of 

 North Durham), and Roxburghshire, respectively. The initials 

 of the contributors are those of Messrs. J. and W. B. Boyd, and A. 

 Jerdon ; and of our correspondents, Messrs. W. Shaw and J. 

 Anderson. The order of arrangement is that of Mr. Wilson's " Eryo- 

 logia Britannica ; " the only satisfactory work on British Mosses. 

 The number of species in the present Flora is 267 ; but several 

 parts of the Borders, which are likely to furnish special diversities, 

 especially the south of Roxburgh, have not been visited j^et; 

 and there are a few generally distributed species that have not 

 put up their appearance. It was not expected that any additions 

 would be made either to the British Flora, or to science in gene- 

 ral ; but so it has come out in the end. The newly-recorded 

 species are Dicranum elotigaium, Dicranodontium aristatum, and 

 Grimmm contoria ; those proposed for new are Campylojms para- 

 doxus^ Hypnum mulcens, and Torhda maritima. If we compare 

 the present list with former ones, or with other Floras, a better 

 idea will be formed of the acquisitions now gained. Pr. Johnston's
