LEONURUS. 



lower spreading, trifid, with the middle lobe obcordate. Stamens 

 didynamous. Anthers approximated in pairs, with parallel 

 transverse cells and naked valves. Achaenia truncate at the 

 apex. 



1024. L. Cardiaca Linn. sp. pi. 817. Eng. Bot. t. 286. 

 Smith Eng. Fl. 104. Benth. lab. 518. — Hedges all over Eu- 

 rope and the middle of Asia. (Motherwort.) 



Herb bitter, with a pungent disagreeable smell. Stems 2 or 3 feet 

 high, wand-like, minutely downy, acutely quadrangular, with inter- 

 mediate channels, purplish, beset with numerous pairs of long-stalked, 

 dark green, somewhat downy, leaves ; the lowermost broadest, and 

 deeply jagged ; upper ones acutely 3-Iobed ; those about the summit 

 lanceolate and undivided. Whorls numerous, axillary, many-flowered. 

 Calyx rigid and pungent. Corolla purplish ; the upper lip clothed 

 with dense, white, shaggy, upright hairs ; lower deeply coloured, varie- 

 gated, smooth, in 3 nearly equal entire lobes. — The reputed tonic 

 powers of this herb, and its use in palpitations of the heart, or in that 

 disease of the stomach called heart-burn, are now little regarded. Yet 

 hence originated its old appellation of Cardiaca. Smith. — A stimulant, 

 which has been extolled by the Russians as a preservative against ca- 

 nine madness. Burnett. 



1025. Galeopsis ochroleuca Lam. is well spoken of as an ex- 

 pectorant, and in phthisical complaints. 



STACHYS. 



Calyx tubular, campanulate, 5-10-ribbed, with the mouth 

 equally or obliquely 5-toothed. Corolla with an equal cylindri- 

 cal tube, usually incurved upwards, not dilated at the throat ; 

 upper lip erect, lower spreading, and 3-lobed, with the middle 

 lobe very large. Stamens didynamous, usually, after bursting, 

 turning towards the sides of the throat ; filaments naked ; an- 

 thers approximated, with distinct parallel divaricating or diverg- 

 ing cells. Style equally bifid. Achaenia obtuse. 



1026. S. Betonica Benih. lab. 532. — Betonica officinalis Linn. 

 sp.pl. 810. Eng. Bot. t. 1142. Smith Eng. Fl. iii. 97. — In 

 most parts of Europe, and in Russia in Asia. (Betony.) 



Root rather woody. Stem leafy, rough with reversed bristles. 

 Leaves oblong, with numerous, strong, bluntish serratures ; the lower- 

 most on long stalks. Flowers crimson, rarely white, forming a dense 

 spike, various in length ; the lowest whorl a little remote, with a pair 

 of small sessile leaves beneath. Bracteas purplish, lanceolate, entire. 

 Lower lip of the corolla more or less notched, or slightly cloven. — 

 This herb is scarcely aromatic, but the fine rigid hairs, which cover the 

 surface, cause it when powdered to produce sneezing. Hence Betony 

 is generally made an ingredient in herb-snuffs. The root is said to be 

 emetic and purgative. Smith.
