248 COMPOSITE. [Tussilago. 



Cream. " Leaves downy opposite subpetiolate 3 — 5 partite, their 

 segments lanceolate deeply serrated, the middle one the longest, 

 heads 5 — 6 flowered, scales of the involucre about 10, 5 outer 

 Qnes short obtuse."— 5r. Fl. p. 230. E. B. t. 428. 



By rivers, streams, and ditches, in moist woods, hedges and other damp or 

 marshy situations ; extremely common. Fl. July — -September. Fr. October, 

 November. 2^. 



Stem erect, from 3 to 5 feet high, rounded, angular and striated, the centre 

 filled with a delicate tissue of mostly hexagonal cells of various sizes, reddish, 

 downy with fine, short, spreading and curved pubescence, more or less copiously 

 and oppositely branched in a corymbose manner, the branches axillary, straight, 

 sometimes a little alternate, erecto -patent. Leaves opposite, dull green, very 

 shortly petiolate or subsessile, 3- or (more rarely) 5-partite, their leaflets unequal, 

 the middle one the longest, lanceolate taper-pointed, sometimes ovate or obtuse, 

 or the uppermost entire, strongly, sharply and unequally serrated, entire at the 

 tips, venoso-rugose and pubescent above, paler and very downy beneath and on 

 the prominent midrib with jointed hairs, and sprinkled, besides, with imbedded 

 resinous globules and granular points. Flowers in dense, much-branched corym- 

 bose tufts, terminating the stem and branches and leafy in their lower part, pale 

 pinkish purple or flesh-coloured, rather agreeably scented, their pedicels and 

 branches of the corymbs with a minute bract at or near the base of each, /rew- 

 Z«i?« almost always 5-flowered, oblong, downy, much shorter than the florets, of 

 about 8 imbricated, ovate or elliptical, erect, concave, obtuse and very unequal 

 bracts, the exterior of which are shorter, smaller and greenish ; the interior larger, 

 broader, and coloured like the florets, with broad, blunt, green keels. Receptacle 

 minute, naked. Florets tubular, sprinkled with resinous globules, the limb gra- 

 dually dilating upwards, its margin in 5 broad, pointed, nearly erect segments. 

 Anthers brownish, with oblong pale and membranous tips. Styles white, much 

 protruded, crimson and bristly at the base just above their insertion, cleft about 

 half-way down, the lobes linear, spreading or slightly recurved, papilloso-glandu- 

 lose, flat on the inner side. Achenium blackish brown or pale, glabrous or some- 

 what hairy, linear-oblong, strongly 5-ribbed or angled, the intercostal faces 

 minutely striated, sprinkled with yellowish, resinous, pedicellate globules ; shorter 

 than the dirty-white, sessile, spinuloso-serrated, single-rowed pappus, which about 

 equals the florets in length, and is very caducous. 



Our British species of Eupatorium is the only European representative of an 

 extensive American genus, though not itself a native of that continent, and is one 

 of the handsomest of its tribe.

" Heads monoecious, all alike. Achenes terete. Pappus pilose. 

 Florets of the ray long, narrow, numerous, in many rows ; of the 

 disk few, sterile (both yellow). Anthers without bristles at the 

 base. Receptacle naked. Involucre formed of a single row of 

 equal, linear scales. (Scapes single-floiverecl, appearing before the 

 leaves)." — Br. Fl.

 cated with scales, leaves cordate-angular toothed downy beneath."
