We have no doubt but the plant here figured is the Jacob&a Senecionis Jolio incano perennis of Ray"s Syncpfis, ed. 

 3. p. 177. It certainly has a lefs jagged, and more groundfel-like leaf, than the common Ragwort. Its leaves and 

 ifalks are alfo in general hoary, efpecially the latter* ; and fo far the defcription difcriminates ; but why perennis ? 

 fince both the aquaticus and Jacob^a, with which it has the greateft affinity, are confidered as perennial. We 

 believe alfo, that our plant is the Jacobaa altijfima, Joliis Erucce /irtemificeve fimilibus et anndis of Ruppius FL Jen. ed. 

 HalL p. 176. And as this defcriptive name appears among thofe which Linnaeus applies to his Erucaflolius, we 

 •confider ourfelves warranted in adopting his name of Erucajolius. Baron Haller, who oftener makes fpecies of 

 varieties, than varieties of fpecies, in the prefent inftance confklers this plant as a variety only of the Jacobs. 

 PrOfeiTor Jacquin, in his Flora Aujiriaca, gives a figure and defcription of a Senecio, which he calls tenuijolius. ; 

 but as he adduces no fynonyms, and as his figure differs in feme refpect from our plant, though we ffrongly fuipect 

 it to be the fame, we dare not confider it as fuch. 



The Senecio Eructejolius, though not fo common as the Jacobsea, is not unfrequent in the neighbourhood of 

 London in certain fituations, particularly in the environs of woods, under hedges, among buihes, &c. and no 

 where more abundant than about the Oak of Honour Wood, near Peckham. The Jacobtea, on the contrary, 

 delights to grow in open hilly paftures, church-yards, by road fides every where : nor do thefe pints differ lefs in 

 their ufual period of flowering; the Erucajolius flowering chiefly in Auguif, a mouth later than the other. 



* This hoarinefs is mod obfervable when the plant is young, or when it grows in a woody and hilly fituation, which it chitfiy affects. When it is 

 Sound in a .moiit i'oil, or cultivated in a gvrden, itiofes this character, in common with many other plants of the lame clai's.
