 ^" Leaves downy, glaucous, nearly feUile, lyrato-pinnatifid, 

 unequally toothed. Flowers corymbofe." — Willdenow 

 defcribed this from living fpecimens, but did not know their 

 native country. T\»Jlem is faid to be ereft, two feet high, 

 branched, furrowed, (lightly downy. Leaves downy on 

 both fides ; pnuiate at the bafe ; pinnatiiid in the middle ; 

 cut at the end ; their kngth two or three inclies ; their feg- 

 ments lanceolate, unequally toothed. Corymbs limple, at 

 the tops of the Item an J branches. Floiuers almoll like the 

 common P. Partbenium.

 n. II. Ait. n. 6. (Chryfanthemum macrophylkim ; 

 Waldlt. et Kitaib. Hung. v. i. 97. t. 94.) — Leaves hairy, 

 nearly fellile, pinnatiiid, toothed, obtufe. Corymb ter- 

 mi.ial, compound. — Native of the woods and mountains of 

 Hungary. Sir J. Banks introduced it, in 1S03, to the 

 Kirw garden, where it is a hardy perennial, flowering in 

 July and Augult. I'his plant refembles Achillea macro- 

 phylla, for which fome botaniits have miftaken it, but is 

 much larger. We have feen no fpecimen.

 Leaves fmooth, pinnate ; leaflets once or twice pinnatifid, 

 ferrated, acute, ipreading. Stem erett, fingle-flowered. 

 Gathered by Touruefort in Iberia. It is found alfo on 

 mount Caucafus, from whence that dillinguilhed cultivator 

 Mr. Loddigps received feeds of tliis elegant fpecies in 1803. 

 The plant proves perennial and hardy, flowering in Augull 

 or S -jiteniber. 'V\\e.Jlem is 12 or 18 inches high, more or 

 lefs leafv, bearing one large handfome^ower, whofe dilk is 

 yellow, and the radius of a rich rofe colour, or crimfon, on 

 its upper fide ; fometimes varying to white. The leaves 

 are from two to four inches long, ftalked, rigid, paler be- 

 neath, pinnate, varioufly ferrated, cut or pinnatifid, all the 

 pouts and fcrratures very acute. Tournefort gathered 

 plan IV of this plant, and his original fpecimens are dif- 

 perfed Iirough many colleftions.

 Ait. n. 8. (Chryfanthemum corymbofum ; Jacq. Auftr. 

 t. 379. Ch. corymbiferum ; Linn. Sp. PI. 1251. Tana- 

 cetum noa odorum ; Ger. Em. 650.) — Leaves pinnate; 

 leaflets lanceolate, pinnatifid, fiiarply ferrated ; the upper 

 ones confluent. Flower-ftalks corymbofe. — Native of 

 mountainous woods in Siberia, and many parts of Ger- 

 many. Gerarde appears, by the catalogue of his garden, 

 to have cultivated it in 1 591^. The root is perennial, woody, 

 with long fibres. Stems erefl, two or three feet high. 

 Leaves fomewliat like Tanfy, but without fcent or talle, 

 except that after a while, according to Jacquin, they caufe 

 a heat or pungency in the mouth. Tlie numerous large 

 whitc^owrt-j-, each with a bright yellow diflc, form an ample 

 terminal corymb.

 (Matricaria Parthenium ; Linn. Sp. PI. 1255. Woodv. 

 Suppl. t. 249. Fl. Dan. t. 674. Matricaria ; Ger. Em.

and cut. Stem branched. Flowers corymbofe. Radius 

 about twice tlie length of the c.il/ :. Seed crcwn toothed. 

 — Native of cultivated orv,'alle ground throughout Europe, 

 fpringing up abundantly with us in neglected gardens or 

 court-yards, flo'aering all iumnier long. The root appears 

 to be rather biennial than perennial. T!,c uliolc herb is 

 bitter and aromatic, hoary or downy. .SVrtn bnfhv. Leaves 

 llalked, fiat and dilated. Flowers numerous, each about 

 the fize of a common daify, but with a large yellowifh diflc, 

 and fhort white radius. Sometimes the Liter' is wanting; 

 and more frequently the flowers are double, the difl{ be- 

 coming white and ligulate, like the radius, but ach Jloret of 

 a fmaller proportion. The recept/icle is flat. 



I J. Y. pnrthenifoltwn. Nari\. 1. Hoary Feverfew. Willd. 

 n. 14. — " Leav", pinnate ; leaflets oblong, obtufe, pin- 

 natifid, toothed. St'^m »and-like. Flowers corymbofe. 

 Radius thrice the length of tlie calyx. Si ed-crown en- 

 tire." — Willdenow defcribid this from a garden, without 

 knowing whence it came. He fays it is very like tlie laft, 

 but has a taller wand-like _y7im, narrower leaves, a rtV/J but 

 half fo large, though the radius is larger, and an er.tire, not 

 toothed, margin totheyf«/. A plant, new become a weed 

 in Kew garden, and iaid to have been imported from China, 

 anfwers precifely to this defcription in every point, except 

 that hs Jlem is fcarcely lefs bufliy than in P. Parthenium. 

 We are perfuaded, neverthelefs, that it is what Willdenow 

 meant. Its leaves are confpicuoufiy hoary, with narrower 

 divifions than thofe of the laft, and the Jlowers, on account 

 of their long and brilliant -white radius, are more Itriking. 

 We have had no opportunity of invelligating the crown of 

 the feed.

 by Desfontaines in uncultivated fields near Tunis. Sib- 

 thorp found it in Greece. The root appears to be peren- 

 nial, bearhig many widely-lpreading or procumbent Jlcms^ 

 a fpan long, which are leafy, and fiighllv branched. The 

 haves are rather fucculent. Floicers terminal, folitary,
