In meadows, pastures, waste ground, and on walls, very common. 



Perennial. May — September. 



Root fibrous, and apparently, as Dillenius observes, perennial. 

 Stems widely spreading or procumbent j among other plants 

 upright. W'^hole herb of a darker green than the preceding, with 

 longer, narrower, rather less obtuse leaves. All the parts of 

 the flower are larger j petals longer and more conspicuous. 

 Flower-stalks generally longer. Seeds rugged. Stam. 10, all 

 perfect. 



Great misconception has prevailed among botanists concerning 

 these two species, owing to Linnaeus having misquoted Vaillant. 

 I have been at some pains to ascertain their respective syno- 

 nyms, from original authorities at Paris and Oxford j but it is 

 impossible to guess what Willdenow intended, as he did not dis- 

 cover the error of Linneeus. Our British botanists, except Mr. 

 Lightfoot, have been regulated merely by the misapplied syno- 

 nyms of Vaillant, and were therefore led astray. The plants 

 are common enough ; but Linnaeus originally described the vis- 

 cosum only, which is really viscid, though his vulgatum bap- 

 pens to be generally more so.
