330 baker's north Yorkshire. 



Aster puniceus L. Alien. Well-established on the York- 

 shire side of the Tees about mid-way between Yarm and Low 

 Worsall, where it was first noticed many years ago by T. J. 

 Foggitt. It now extends for a couple of yards along the bank 

 of the river. I am not quite certain about the name, but believe 

 the plant to be a narrow-leaved form of the American A. puniceus. 



SolidagO Virgaurea L. British type. Native. Area 

 general. Range 0-550. Frequent amongst the hills of both 

 east and west, especially by the stream-sides where they break 

 through the limestone. It grows also in the Howardian tract, 

 upon the basaltic dike in Cleveland, and amongst the coast 

 banks at Mulgrave, Robin Hood's Bay, and Scarborough. In 

 the Central Valley I know of it in one station only, a wood by 

 the Tees side at Stapleton. It has been found lately by A. R. 

 Waller in small quantity at Sandburn and Strensall. 



Senecio vulgaris L. British type. Native. Area general. 

 Range 0-400. Common in waste places, ascending to Upper 

 Cronkley, Sleightholme, and Keld. 



Senecio sylvaticus L. British type. Native. Area general. 

 Range 0-300. Frequent upori sandy heaths throughout the 

 lower zone, ascending to the flagstone quarries of Leyburn Moor. 

 S. viscosus, except as an Alien, is quite doubtful as a plant of 

 our limits. 



Senecio erucsefolius L. English type. Native. Area

 low country. Ascends Wensleydale to Carperby;y". Percival.

 plateau of Kisdon. 



Senecio aquaticus Huds. British type. Native. Area 

 general. Range 0-400. Common in damp places, ascending 

 nearly to the head of Coverdale, and in Gretadale to Sleight-
