TUSSILAGO. 



fimple, of many equal, fomewhat membranous leaves ; tu- 

 mid at the bafe. 



Obf. Liniixus remarks, that Petajites of Toumefort 

 has no ligulate florets in the radius, though fome female 

 naked ones occur : Tujfilago of the fame author has always 

 female florets in the radius, furnifhcd with a ligulate corolla : 

 ylnandria of Linnsus himfelf, Am. Acad. v. i. 243, has 

 fefllle feed-down ; and T. frigida varies with or without a 

 radius. Thefe circumftances are indeed variable at all times, 

 but efpecially in the genus now under confideration. We 

 have mentioned in Fl. Brit, that fome reputed fpecies ap- 

 pear to be but different fexes of one and the fame. Of this 

 the Britifh 7". hybrida and Petafites are one inftance. We 

 lliall indicate other fimilar cafes, in which it feems Ehrhart 

 has forellalled us, in his Beitrage, v. 3. His difcoveries are 

 confirmed by Hoppe ; and both thefe authors are followed 

 by Willdenow, without any reference to the Flora Britannica, 

 to which however the publication of Hoppe is three years 

 pofterior. We are well affured that this apparent negleft 

 was not intentional, and the obfervations in queftion, having 

 been made by each perfon independently, derive from thence 

 the more authority. The whole genus of TuJJilago is herba- 

 ceous, without zny Jlem. Leaves ftalked, fimple, angular, 

 toothed, more or Icfs heart-rtiaped. Pulrfcenee of the herbage 

 cottony, denfe, generally remarkable for its pure whitenefs, 

 and foft texture. Flowers white, or pale red ; fometimes 

 yellow ; either folitary, or denfely panicled. Seed-down of 

 a brilliant filvery white. — Willdenow reckons up twenty-one 

 fpecies, but his firft two, 7'. Anandrla and lyrata, will be 

 found under our article Perdkium, fp. 3. and 4 ; his T. 

 lyrata beisg Gmelin's t. 67. f. 2, mentioned under our Per- 

 (lic'ium popuUfolium, n. 4, as a probable variety of Anandria. 

 Willdenow's 4th fpecies, T. integrifoUa, is Chaptalia lomen- 

 to/a, Venten. Jard. de Cels 61. Purfli 577. If not a good 

 genus, it mull be referred to Perdkium ; being certainly no 

 Tujftlago. Very pofiibly the third fpecies of Willdenow may 

 alio belong to Perdkium ; but this being a very uncertain 

 plant, known from Plumier's figure only, we muil leave it 

 as we find it, amongft other fpecies placed here by authors, 

 but which to us are by no means free from doubt as to their 

 generic charadlers ; nor can that queftion be decided without 

 an inveftigation and comparifon of their frefli flowers. 



1 . T . dentala. Toothed Weft Indian Colt's-foot. Linn. 

 Sp. PI. 1213. Willd. n. 3. (After acaulos, hieracii villofis 

 foliis ; Plum. Ic. 28. t. 40. f. 2.) — Stalk fingle-flovvered, 

 naked. Flower radiated, ereft. Leaves feflile, oblong, 

 wavy, toothed, villous. — Gathered by Plumier in the Weft 

 Indies. The root appears to be fibrous. Leaves numerous, 

 three or four inches long, with an undulated ftrongly 

 toothed margin. Flo-wer-Jlalts alfo numerous, though fewer 

 than the leaves, fmooth. Flowers radiated, fomewhat like 

 our common T. Farfara, but much fmaller. 



2. T. albicans. Whitifli Jamaica Colt's-foot. Swartz 

 Ind. Occ. 1348. Willd. n. 5. ( Leontodon tomentofum i 

 Linn. Suppl. 347.)— Stalk fingle-flowered, naked ; cottony 

 at the top. Flower radiated, drooping. Leaves ftalked, 

 obovate, with flight reverfed ferratures ; cottony beneath ; 

 tapering at ,the bafe.— Native of dry grafly inland paftures, 

 in the weftern part of Jamaica. Swartz. Sent to Lm- 

 iiseus in Browne's herbarium. Root fibrous, probably pe- 

 rennial, though marked annual. Leaves two or three mches 

 long, of a narrow obovate form ; green and nearly naked 

 above ; fnow-white beneath ; their margin flightly wavy, 

 befet with minute diftant teeth, all pointing backwards. 

 Stalks few, often a foot high, round, reddifli, deftitute of 

 fcales or IraBeas, clothed about the top, for near two mches, 

 v/ith denfe cottony down. Flower white, droopmg as it 



fades ; according to Swartz's defcription it anfwers to the 

 characters of this genus. Seed-down fliining, with a reddifli, 

 or pink, hue. 



T,. T . pimila. Dwarf Jamaica Colt's-foot. Swartz Ind. 

 Occ. 1350. Willd. n. 6. — Stalk fingle-flowered, naked, 

 downy. Flower radiated, eredl. Leaves obovate, with 

 reverfed teeth ; finuated at the bafe ; downy beneath. — 

 Found on tlie lofty calcareous mountains of the fouth part 

 of Jamaica, near Cnld-fpring, flowering in fummer. Smaller 

 than the laft, to which it feems nearly allied ; but the leaves, 

 only an inch or two in length, are pinnatifid in a lyrate man- 

 ner. Stalk moftly folitary, from three to fix inches high, 

 roundifli, cottony ; purplifli in the lower part. Flower 

 fmall, white ; ereft according to Willdenow, and the fpe- 

 cific charafter of Swartz, though the latter calls it droop- 

 ing in his defcription. Its ftruflure is that of a Tujfdago. 



4. T. nutans. Drooping Jamaica Colt's-foot. Linn. Sp. 

 PI. 1 2 13. Am. Acad. v. 5. 406. Willd. n. 7. Ait. n. i. 

 Swartz Obf. 305. (Leontodon n. i ; Browne Jam. 310. 

 Dens leonis, folio fubtus iiicano, flore purpureo ; Sloaiie 

 Jam. V. I. 255. t. 150. f. 2. After primulae veris folio, 

 flore fingulari purpureo; Plum. Ic. 29. t.4i.f. i.) — Stalk 

 fingle-flowered, naked, cottony. Flower radiated, pendu- 

 lous. Leaves ftalked, oblong-heartfliaped, wavy, toothed ; 

 cottony beneath ; finuated at the bafe. — Native of culti- 

 vated and graify places in Jamaica. Swartz defcribes it as 

 annual. Mr. Aiton marks it biennial, flowering in the ftove 

 in June and July. The much larger leaves, near a fpan 

 long, pinnatifid in a lyrate manner, and the Jlalls twelve or 

 fifteen inches high, diilinguifli this fpecies from all the pre- 

 ceding. The Jlower is pendulous, with a white diflc and 

 radius, but the flender points of the calyx-fcales being tipped 

 with purple, have, as it appears to us, been miftaken for a 

 purple radius by Sloane, and even by the more learned pro- 

 feflbr Swartz. When mfeed, the ftalk becomes creft. The 

 down is rather tawny, or reddifli. 



5. T. trifurcata. Three-forked Colt's-foot. G. Forfter, 



Pi. Magell. 28. Willd. n. 8 Stalk fingle-flowered, fcaly. 



Flower radiated, ereft. Leaves fpatulate, with three or 

 more oblong fegments, fmooth. — Native of dry hilly fitua- 

 tions about the ftraits of Magellan. Root perennial, feme- 

 what tuberous. Leaves radical, tufted, an inch long, di- 

 vided into three, four, or five, oblong, ered, finger-like 

 fegments, fpreading, quite fmooth and naked. Stalk from 

 one to three inches high, round, clothed with awl-fliaped 

 fcaly braaeas. Flower white, with all the characters of its 

 genus. Inner fcales of the calyx largeft, with fpreading 

 horizontal points.

 —Stalk fingle-flowered, with oblong fcattered brafteas. 

 Flower without rays. Leaves kidney-fliaped, toothed, 

 fmooth on both fides — Native of the alps of Auftria, Bo- 

 hemia, Switzerland, &c. flowering in June and July. The 

 root is perennial, tuberous, and creeping, brown, with many- 

 long fibres. Leaves kw, radical, ftalked, from one to two 

 inches broad, bluntly toothed ; quite fmooth, and of a ftiin- 

 ing o-reen, reticulated with deprefled branching veins above ; 

 paler beneath, but equally fmooth, except fome hairs on the 

 ribs or veins. Stalk folitary, a foot or more in height, erett, 

 purphfti, hairy, bearing a few diftant, varioufly fliaped, con- 

 cave, upright braaeas. Flower ered, half an inch broad.

 all regular and five-cleft, with purple anthers and ftgmas.
