form and obliquely truncate at the summit, or more rarely ter- 

 minated by a short ligulate limb. Style with semi - cylindrical 

 thick obtuse branches, stigmatiferons all over. Achenes fusiform, 

 cylindrical, crowned with a hairy pappns, longer and of more 

 numerous hairs in the female florets. 



Perennial herbs, with cordate radical leaves and scapes with 

 scaly bracts or small alternate leaves, terminated by a corymb 

 raceme or thyrsus of anthodes of white or pale-purple florets, 

 appearing with or before the leaves. 



The name of this genus comes from ireraaoQ [pefasos), a cover, which the leaves 

 afford.

Tussilago fragrans, Vill. , 



Leaves evergreen, round, deeply cordate, with the lobes sub- 

 parallel, finely or evenly denticulate ; at first arachnoid-floccose, 

 at length glabrous above, — pale-green, sparingly downy and with 

 articulated hairs beneath. Plorets in a roundish-ovoid or oblong- 

 ovoid racemose panicle, scarcely elongating after flowering. Phyl- 

 laries acute. Corolla of the female florets filiform, terminated by 

 a distinct though short ligule. Branches of the stigma in the sub- 

 male florets rather short, sub- cylindrical, acute. 



Roadsides and plantations. Completely naturalized in many 

 places, as in the Isle of Wight, Upper Deal (Kent), Surrey, Mid- 

 dlesex, banks of the Esk above Musselburgh, &c. 



[England, Scotland.] Perennial. Winter and early Spring. 



Rootstock extensively creeping. Leaves appearing in spring, 

 and in favourable situations remaining green until the young leaves 

 appear in the succeeding season, 4 to 8 inches across, with a very 

 deep sinus ; the lobes sub-parallel at the base, and then diverging 

 (a small portion of the base of the lobe is bounded by the lateral 

 veins, but not so largo a part as in P. vulgaris). Scapes 4 to 9 inches 

 high, with scale-like empty bracts, the lower ones often terminated 

 by a small lamina. Anthodes very shortly stalked. Periclinc about 

 \ inch long. Corolla pale-lilac. Anthers purple. Style-branches
