form and obliquely truncate at the summit, or more rarely ter- 
minated by a short ligulate limb. Style with semi - cylindrical 
thick obtuse branches, stigmatiferous all over. Achcnes fusiform, 
cylindrical, crowned with a hairy pappus, longer and of more 
numerous hairs in the female florets. 
Perennial herbs, with cordate radical leaves and scapes witli 
st-;ily 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 uauie of this genus comes from ttetcktoc (petasos), a cover, which the leaves

Leaves evergreen, round, deeply cordate, with the lobes sub- 
parallel, finely or evenly denticulate ; at first araclmoid-floccose, 
at length glabrous above, — pale-green, sparingly downy and with 
articulated hairs beneath. Elorets in a roundish-ovoid or oblong- 
ovoid racemose panicle, scarcely elongating after flowering. Phyl- 
laries acute. Corolla of the female florets filiform, terminated by 
:i distinct though short ligule. Branches of the stigma in the sub- 
male florets rather short, sub-cylindrical, acute. 
lloadsides and plantations. Completely naturalized in many 
] 'laces, 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. 
Rootstoek 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 
nail portion of the base of the lobe is bounded by the lateral 
reins, but not so large a part as in P. vulgaris). Scapes 4 to 9 inches 
high, with scale-like empty bracts, the lower ones often terminated 
a small lamina. Anthodes very shortly stalked. Pericline about 
ch long. Corolla pale-lilac. Anthers purple. Style-branches
