Akin to the last, of which Linnaeus, Haller and others have consi- 

 dered it as a variety ; while many have confounded herewith an 

 Austrian and Swiss plant, Jacobcea tertia, latifolia prima, Clus. 

 Hist. V. 1. 23./; which is Haller's Senecio 7i. 63; and the alpinus 

 oi Linn. Suppl. 371, where all the synonyms are wrong. Our 

 aquaticus, first distinguished and named by Hudson, is generally 

 very smooth, rarely, in accidentally dry situations, a little cot- 

 tony, of a lighter green than the preceding, and its leaves, 

 though very variable, always much less divided ; tlie lower ones 

 stalked, ovate, nearly entire ; upper pinnatifid in a lyrate man- 

 ner, having a few parallel lobes at the base, and a large, ovate, 

 serrated termination. Fl. few and larger, though of the same 

 golden hue, with more elliptical radiant florets. Seeds of the 

 radius, as well as of the disk, destitute of the hairy or silky 

 clothing which is nearly universal in the whole genus, and which 

 essentially distinguishes the seeds of the disk of S. Jacobcea from 

 the present, whose marginal seeds only have a slight roughness 

 at the edges, near the top. The scales of the outer calyx 

 moreover are very few. Mr. Woodward remarked that the ra- 

 dius is sometimes wanting. The lower part of the stem often 

 assumes a violet hue, but such is frequently the case with 51. Ja- 

 cobcea.
