Root somewhat creeping, with branched fibres. Stem erect, from 

 three to four feet high, leafy, stout, smooth, furrowed, or angular, 

 simple, or branched upwards. Leaves alternate, bi-pinnate, dilated at 

 the base into a reddish brown membranous sheath, enveloping the 

 stem, with ovate acuminated auricles, toothed on the margin, the 

 upper ones sessile, the lower on long angular furrowed footstalks, 

 lea/lets a deep shining green, above smooth, pale, dull, or somewhat 

 glaucous beneath, two or three toothed, or deeply cleft, the margins 

 more or less recurved, ovate, wedge-shaped, rounded or heart-shaped 

 at the base, the upper leaflets almost linear, reticulated with veins. 

 Inflorescence a terminal erect sub-corymbose panicle. Flowers nume- 

 rous, densely crowded, evcct, pedicles short, hrccteas lanceolate, smooth. 

 Calyx of four ovate lanceolate concave pieces, pale yellow. Stamens 

 with a short erect filament, and oblong acute anthers, yellow, of two 

 linear cells. Stigmas sessile, oblong, spreading. Capsules ovate, 

 acute, smooth, deeply furrowed. 



Habitat. — Damp banks and margins of rivers, not luifrequent; 

 " less frequent in Scotland, and principally found in the vale of the 

 Clyde." — Hooker. ^. Isle of Bute, and about Lincoln. 

 Perennial ; flowering in June and July. 



This is an extremely variable plant in the shape of its leaflets, from 

 narrow lanceolate to roundish ovate, and wedge-shaped, and either 

 entire or one or two cleft into lanceolate or acute teeth. 'When the 

 lower leaves are three cleft, wedge-shaped, and the upper linear oblong, 

 it is the T, nigricans, Jacq. and T. heterophyllum, Lej. 



The plants of this genus possess bitter somewhat cathartic properties, 

 but are not now used in medicine. They are not relished by cattle, 

 and are refused by them, except when mixed with other herbs. The 

 T.flavum has been used as a yellow dye for woollen goods, but is not 

 much valued.
