** Scales of the receptacle and pistillate florets in 5 rows. Gifola. 
3. F. Germdnica L. ( common F.) ; stem erect usually pro- 
liferous at the summit, leaves downy, heads globose-capitate in 
the axils of the branches and terminal, scales of the involucre 
cottony with the points cuspidate and glabrous. — a. heads 
obscurely 5-angled not surrounded by leaves, scales of the in- 
volucre longitudinally folded yellowish-white at the apex, 
leaves oblong or lanceolate, acute or apiculate. Gnaphalium 
Huds. : E.B. t. 946. — /3. heads prominently 5-angled sur- 
rounded by 1 — 2 blunt leaves, scales cymbiform purplish 
towards the apex, leaves grass-green with a yellowish to- 
mentum lanceolate obtuse mucronate. F. apiculata G. Sm. 
F. lutescens Jord. — y. heads prominently 5-angled surrounded 
by 2 — 3 acute leaves, scales cymbiform yellowish-white at the 
apex, leaves of a leaden grey colour spathulate. F. spathulata 
Presl. 
Sandy and gravelly places, and dry pastures. — /3. and 7 . in various 
places in England. ©. 7 — 9. — Stems 6 — 8 inches high, erect, 
very leafy, terminated by a globular tuft of small ovate or conical 
heads of flowers, from beneath which usually spring 2 — 3 or more 
horizontal branches, in a proliferous manner, each terminated by a 
head of flowers. This curious mode of growing occasioned the term 
of Herba impia to be applied by the old botanists to this plant, as if 
the offspring were undutifully exalting itself above the parents. In 
a. and j 8 , the heads are half sunk in tomentum, and scarcely at all so 
in 7 . 
33. Petasites Garin. Butter-bur. 
Subdicecious. Heads monoecious (of two kinds and on dif- 
ferent plants; either with many central tubular sterile florets 
surrounded by a row of truncate filiform fertile pistillate ones ; 
or with 1 — 5 central sterile tubular florets surrounded by many 
rows of filiform fertile pistillate ones). Pappus pilose. Anthers 
without bristles at the base. Receptacle naked. Involucre 
imbricated in two rows of lanceolate herbaceous scales. (Scapes 
with a many-headed thyrsus, appearing before the leaves.) — 
Name : rtranoc, a covering to the head, or an umbrella ; from the 
great size of its foliage. 
1. P. vulgaris Desf. ( common B.)\ leaves roundish-cordate 
unequally toothed downy beneath, the lobes approximate a. 
florets nearly all sterile. Tussilago Petasites L. : E. B. t. 431. 
— /3. florets nearly all fertile. Tuss. hybrida L.: E. B. t. 430. 
Wet meadows, to which it is very injurious, and road-sides. 
3 — 5. — Rhizome extensively creeping, and thus multiplying the 
plant. Leaves very large. Flowers (appearing before the leaves) of 
a pale flesh colour, smaller, more lax, and in a longer thyrsus on the
