 and distributed through the Bot. Exch. Chib of that year by the 

 author. 



3. Pang. Near Sulham, Tufnail. 



The locality where this interesting addition to the Thames province 

 was found by Mr. Tufnail, is a grassy slope on which the prevailing 

 vegetation consists of Galium MoUvgo, var. insuhricum, Gentiana Amarella. 

 As2)erula Cynanchica, Campanula glomerata, Bromus erectus, Avena pubescens, 

 &c. A few larches have been planted in the vicinity, and there is 

 a patch of Euphorbia Cyparissias on the same slope, but it is not very 

 near to the Galium, which I am disposed to think may be a native 

 species here. It is not the typical plant, but the variety with narrower 

 hairy leaves to which the name G. nitidulum, Thuill. Fl. Par. ed 2, 76, 

 is applied, and is the G. sylvestre, var. pubescens of Schrad. .Spic. 13, 

 according to Koch. 



G. sylvestre is not reported^ from any of the bordering counties.
