dipped in a solution of saltpetre, and dried in the sun, makes an excellent tinder. The leaves are the basis of 
the British herb tobacco ; they have been regarded as expectorant from the earliest ages, having been smoked 
through a reed in the days of Dioscorides, with the view of relieving the chest from accumulated mucus in 
catarrh, asthma, and phthisis. At present, though it occupies a place in the Materia Medica, very little 
reliance is placed on its powers. {London Disp. p. 542.) 
T. Petasites, from the Greek •rtTccffos, a broad covering, in allusion to the leaves, which are larger than 
those of any British plant, and afford shelter from rain to poultry and other small animals. It is called Butter 
bur, in allusion to a former application, and Pestilent-wort, from its supposed efficacy in the plague. T. hybrida 
is by some considered, a variety of this species, as T. alba is of T. paradoxa. T. fragrans is valued in gardens 
as an early and fragrant flower ; like all the species, it is apt to run very much, and is therefore best kept in 
pots. 
It is remarkable that no plant belonging to the tribe of Tussilagine£e, has been discovered with hermaphro- 
dite flowers. They are distinguished from other tribes by their stigma, which occupies both surfaces of the 
lobes of the style. They are nearly all natives of Europe.
