numeroufly crowded about the bottom of each leaf, render- 

 ing it, in a manner, lyrate, and furrounding the ftem or 

 branch. Branches iomewhat corymbofe, each terminated by 

 a rather large _y?owf/-, with long white rays, and a prominent 

 yellow difk. The late Mr. Crowe once found in Norfolk a 

 partly double-flowered variety.

 pinnate ; fegments hnear, poiiitlefs, fleftiy ; convex above ; 

 keeled beneath. Stem diifufe. Seed-crown lobed. — Native 

 of the fea-coaft in the north of Europe. Found in feveral 

 parts of Scotland, as well as on the foutli coaft of England, 

 and in Lancafliire and Durham, flowering in July and 

 Auguft. The root is perennial. Stems numerous, prol- 

 trate, fpreading circularly to the extent of two or three 

 feet. The leaves are more flefliy than in the foregoing ; 

 the dilk of the Jloiver broader, in proportion to the length 

 of the rays ; and the crown of the Jecd divided into three or 

 four lobes. The whole herb is (lightly aromatic, and of a 

 darker more (hining green than hiodorum. 



20. P. parinjlorum. Small-flowered Feverfew. Willd. 

 n. 19. — "Leaves doubly pinnate; leaflets linear-thread- 

 fhaped, in two or three deep divilions. Stem ereft, 

 branched. Seed-crown two-lobed." — Defcribed by Will- 

 denow from living fpecimens, but the native country of this 

 fpecies is unknown. It is faid to be annual, greatly re- 

 fembling P. inodorum, but having a taller and upright 



Jlem ; a fhorter radius ; and a green two-lobed crown to 

 the feed.

 n. 20. (Chryfanthemum multicaule ; Desfont. Atlant. 

 V. 2. 2S2. t. 236.) — Leaves fimple, fmooth, fpatulate ; 

 the lower ones toothed. Stem erecl, much branched from 

 the bottom. — Native of fandy hills near Mafcar, in Bar- 

 bary. Root fibrous, apparently annual. Stem branched 

 from the bafe principally, bufliy ; the branches naked above, 

 each bearing a folitary Jloiver, about as big as a French 

 Marygold, whofe radiant florets are yellow, and of a very 

 broad elliptical form, about eight or nine or number.

 n. 21. (Chryfanthemum trifurcatum ; Desfont. Atlant. 

 V. 2. 281. t. 235. f. 2.) — Leaves fleihy, fmooth, linear, 

 acute ; the lovvermolt pinnate ; the uppermolt uadivided. 

 Stem afcending, fingle-flowered. — Native of fields near 

 Kerwan m Barbary, flowering in winter. The Jlem is 

 fimple, a foot high ; leafy below ; naked above ; terminated 

 by a very large Jloiver, with numerous yellow radiant 

 florets. Some leaves are partly bipinnate ; others three- 

 cleft ; the uppcrmuit fimple ; all linear, wavy, acute, and 

 of equal breadth.

 leaflets linear-awl-fliaped : upper ones linear, undivided, and 

 entire. Stems fingle-flowered. — Native of Spain and Si- 

 cily. Willdenow delcribes it thus from dried fpecimens. 

 «' Root many-headed, woody. Stems feveral, fimple, a fpan 

 high, fingle-flowered. Leaves hoary ; the radical ones 

 tlalknl, oblong, fading when arrived at maturity, and alto- 

 gerlier wan'ing when th.e Jloiuers open; lower ftem-leaves 

 itafked, piri.ate at the extremity, with three or four pair of 

 very (hort linear-awl-fliaped leaflets, and a membranous 



linear footflalk ; the upper ones linear, feffile, and entire. 

 Rays of the corolla pale yellow. It refemblcs Chryfanthe- 

 mum peBinatum, but differs abundantly in the calyx not being 

 membranous, and in having a crown to kSw feed." 



We know nothing of Ado's plant. Willdenow cites an 

 additional fynonym, Barrclier's t. 1153. f. 1, which feems 

 to have no afiinity to the figure of Boccone, and much more 

 refembles Cineraria minula, Cavan. Ic. t. 33. f. 3, under 

 which indeed Willdenow likewife quotes it, Sp. PI. v. 3. 

 2086. 



24. P. orientale. Oriental Yellow Feverfew. Willd. 

 n. 23. — " Leaves doubly pinnate; leaflets linear. Stems 

 afcending, fingle-flowered." — Native of Georgia. Stems 

 fix inches high, naked above. Lower leaves an inch long ; 

 the upper ones half as long, and onlv fimply pinnate. 

 Scales of the calyx withered at the edge. Flowers deep 

 yellow, the fize of Chryfanthemum fegelum. Willd.

 Leaves doubly pinnatifid, linear, bluntifli. Stem corym- 

 bofe. Rays half as long as the diameter of the diflc. — Na- 

 tive of Siberia. A hardy perennial, flowering throughout- 

 the fummer. The Jlem is twelve or eighteen inches high, 

 leafy, branched and corymbofe, bearing eight or more long- 

 ftalkcd y eWow Jloiuers, whofe diflc is about half an inch 

 in d'.ameter, and their radiant florets of a fliort roundifli 

 figure, hardly extending a quarter of an inch from the difl<. 

 Seed-croiun toothed. Leaves doubly and interruptedly pin- 

 natifid, with linear, bluntifh fegments, each tipped with a 

 minute point ; their furfaces both downy, or fomewhat 

 filky. The leaves, as well z.% Jloixiers zx\<^ feeds, are very 

 diftinft from Chryfanthemum italicum, to which Linnxus 

 compares this fpecies.

 t. 85. f. I. Chryfanthemum bipinnatum ; Linn. Sp. PI. 

 1255.)— Leaves doubly or triply pinnatifid ; their fegments 

 dilated upwards, minutely pointed. Stem nearly fimple. 

 Rays wedge-fliaped, not a quarter fo long as the diameter 

 of the diflc. — Native of Siberia, flowering in June. Intro- 

 duced at Kew by Mr. Bufli, in 1796. This differs from 

 the lail in having more compound leaves, whofe ultimate 

 fegments are almoft elliptical, and all their points diftinftly 

 awned. But the flowers efpecially differ in being fewer, 

 from one to three on e2.ch Jlem, and furnilhed with a diik 

 near an inch wide, while tlieir radiant marginal florets are 

 fhort, broad, and wedge-fliaped, with broad Ipreading teeth. 

 The calyx, as well as all the herbage, is fhaggy with foft 

 hairs. 



27. P. indicum. Eall Indian Yellow Feverfew. Sims 

 in Curt. Mag. t. 152 1, Ait. n. 15. — Leaves pinnatifid; 

 their fegments dilated upwards, lobed. Stem branched. 

 Flowers on long ilalks, nearly globular. Radiant florets 

 few, very fliort.— Sent by Dr. Roxburgh, from the Eafl 

 Indies, to A. B. Lambert, efq. It proves a hardy annual 

 in our gardens, flowering moft part of the fummer. The 



Jlem is much branched, but the pinnatifid, though more 

 fimple and broader, leaves, betray an affinity to the two laft 

 fpecies, which is confirmed by the (hort yellow radiant, 



Jlorets. Thefe however are, according to Dr. Sims, moil 

 generally wanting, l^hejlowers are folitary, on long fwelL. 

 ing furrowed Jlalis, terminating each branch; tiieir di(k 

 nearly an inch wide, and finally convex. The herbage ap. 

 pears to be fmooth.
