{Root much creeping. Leaves , which come off after the flowers, excessively 
large, all radical, on long foot-stalks. Scape a span high, thick, and 
scaly, with lanceolate spreading bracteas. Flowers purplish. Some 
plants have all th e florets with perfect germens, in which case the stigma 
is deeply cleft and linear, and the anthers are imperfect and not united ; 
others have imperfect germens, when the stigma is very much incrassated 
and ovate, tuberculated, and very slightly notched, whilst at the same 
time the anthers are perfect, united, or syngenesious, purple, with white 
pollen. The former with perfect germens, producing no seed , have al¬ 
most universally gone by the name of T. hybrida , and to the latter the 
name of T. Petasites has usually been confined. As these plants frequent¬ 
ly grow separate, the fruit is rare ; but nature has made ample amends, 
and by the long creeping roots this species is multiplied, and proves very 
destructive to pasture lands. Hook. E.) 
(Th e fertile plant, (as first suggested in England by Smith, and on the Conti¬ 
nent by Ehrhart, though the former learned author deems it more correct 
to consider it as a casual variety in which the fertile or seed-bearing 
organs predominate,” rather than as the proper fertile plant), T. hybrida, 
of authors, figured in Hook. FI. Lond. 129. E. Bot. 430. Dill. Elth. p. 
309. t. 230,) is this minutely described by Prof. Hooker. “Root, leaves, 
flower-stalk, thyrsus, bracteas, and involucre, precisely similar to those of 
the barren state of T. Petasites, except in the thyrsus being more elongated. 
Flowers nearly all fertile, very few barren. Fertile florets slender, tubular, 
of a purplish rose-colour, slightly incrassated above, the limb quinquifid, 
erecto-patent. Barren-florets very few, rather shorter and broader than 
the fertile ones, thickened upwards, limb quinquefid, patent. Stamens 
inserted above the middle of the carolla. Filaments white, short. An¬ 
thers oblong, furnished with, an appendage at the extremity, purplish. 
Pollen white. Germen ovate, smooth, abortive. Style filiform, white, 
a little longer than the corolla. Stigma remarkably incrassated, minutely 
tuberculated, acute and bifid at the extremity. Anthers none. Germen 
ovate, striated. Style somewhat longer than the corolla, filiform, white 
Stigma slightly incrassated, bifid. Pericarp ovate, striated brown, ter¬ 
minated by a white sessile, simple, scabrous pappus.” E.) 
{Long-stalked Colt’s-foot or Butter-bur. T. Petasites, fsem. As the 
first described is the sterile, so this is the fertile state of the same 
plant, and not a distinct species, as generally designated under the name 
of T. hybrida. It grows in similar situations, but is less abundant. E.)

the parasitic fungus Ly coyer don epiphyllim , hence designated AScidium Tussilagum, E.)
