TETRADYNAMIA— SILICULOSA. Senebieva. 179 



pinnatifid and cut. Fl. small, white, in clusters opposite 

 to the leaves. 

 There has been much controversy respecting the Coronopus 

 of antient authors, some taking it for Cochlearia Corono- 

 pus of Linnaeus, others for his Plantago Coronopus^ others 

 for Myosunis, or for Achillea Ptarmica, while that of 

 Pliny seems by his description very different from all 

 these, as well as from what Dioscorides intended. Dr. 

 Sibthorp, the professed object of whose journey was to 

 determine the old Greek names, fixed upon Lotus ornitho- 

 podioides as the true xopuvoTrous ; though in his journal, 

 printed by the Rev. R. Walpole, Travels in the East, 

 1 02, he speaks of Cochlearia Coronopus as the plant of 

 Dioscorides, still called xoupowoTroBi in the isle of Fanno, 

 and eaten as a pot herb. It seems to me that the name 

 in question was applied by the antients to various plants, 

 whose roots were crowned with radiating depressed 

 leaves. In this obscurity, where nothing can really be 

 ascertained, though I had originally followed Gaertner, 

 I now cannot but agree with my friend DeCandolle, in 

 preferring the name by which he has commemorated a 

 most eminent physiological botanist, the Rev. M. Sene- 

 bier of Geneva. Of his merits there can be no doubt, 

 nor can the characters of this genus, as distinct from every 

 other of its tribe, ever come in question.
