SYNGENESIA— POLYGAM.-SUPERF. Seiiecio. 433 



of the radius near a dozen, more or less, oval, broad, entire at 

 the extremity, for the most part spreading, but as they fade they 

 become revolute. Seeds a little silky, Down roughish. The 

 scent of the herb is like Tansy or Mugwort. 

 Baron Bivona Bernardi has sent, along with specimens agreeing 

 precisely with our Oxford plant, others with perfectly undivided, 

 entire or toothed, leaves, always indeed clasping the stem; such 

 as are figured in Bonanni's edition of Cupani, t. 168./. 1; ^ 161. 

 /. 2; and t. 160./. \; as well as in Cupani's original publica- 

 tion, one of the rarest books on Botany. Our plant does not 

 show any disposition to vary in this extraordinary manner, 

 whatever may be the case in Sicily. The above authority how- 

 ever is indisputable, nor are intermediate specimens wanting, 

 which strongly confirm it. The Baron had no means of know- 

 ing that his plant was S. squalidus of Linnaeus, nor does it de- 

 serve so opprobrious a name.

In woods, hedges, and by road sides, in the chalky or gravelly 

 counties. 



Perennial. July, August. 



Root somewhat creeping, with long stout fibres. Stem erect, 

 straight, unbranched, usually 2 or 3 feet high, leafy, furrowed, 

 covered slightly with loose cottony down ; corymbose at the 

 top, with several bright y eWow Jiowers, on bracteated stalks. 

 Leaves numerous, alternate, deeply pinnatifid, sparingly toothed, 

 sessile, often with several clasping lobes at the base ; dark green 

 and nearly smooth above ; downy or cottony, often snow-white, 

 beneath ; their segments either flat or revolute, extremely va- 

 rious in width. Inner scales of the calyx much fewer than in 

 any of the preceding, broader and flatter, with a membranous 

 border, blackish at the tip ; outer spreading, linear-lanceolate, 

 pale at the point, and much resembling the bracteas immediately 

 below them. Florets of the radius linear-oblong, minutely 3- 

 toothed, revolute in fading. Seeds hairy. Down rough.
