E. Med. — Abundant near the sluice at the bottom of Brading harbour. Shores

 in salt-marshes near Yarmouth. 



Root tough, woody and flexuose, usually but little branched, running deeply 

 and mostly obliquely, covered with a blackish brown wrinkled bark, dividing at 

 the crown into several stems, which are tortuous, recumbent, spreading and some- 

 what ligneous below, then erect or ascending, slender, sharply angular, copiously 

 branched and leafy, seldom much above a foot in height, clothed, as well as the 

 leaves, with an abundant, close, cottony web less plentiful at the base of the stem, 

 which is usually beset with the withered leaves of the previous year, or naked and 

 of a greenish or yellowish brown colour, and glabrous or nearly so. Leaves nume- 

 rous, alternate, very white or hoary, especially those of the barren shoots, which 

 are crowded into dense tufts ; on moderately long grooved petioles, small and of 

 a roundish or oblong shape, deeply pinnatifid or pinnatisect, the secondary seg- 

 meuts linear-oblong, entire, rounded or obtuse, either spreading or erect and 

 folded together, flat above and somewhat keeled beneath, rather thick and succu- 

 lent, those of the stem-leaves becoming for the most part less numerous as they 

 approach the summit. Heads mostly 6-flowered, oblong, small, secund, nodding 

 or drooping, sometimes erect (A. gallica, L.), mostly solitary and distant, in more 

 or less unilateral, axillary, leafy, simple or slightly compound racemes, of which 

 the inferior are long, spreading or patent, drooping at the tips, the superior short 

 and strongly recurved, with closer-placed heads. Florets all perfect, yellowish or 

 reddish, glabrous, resinous, the limb cleft at the summit into 5 short, erect, trian- 

 gular segments ; tube greenish. Anthers apicnlate. Styles exserted, very thick, 

 cleft into 2 rectangular, slightly diverging, yellow lobes with dettexed margins ; 

 stigmas disciform, semicircular, fringed with pellucid bristles. Receptacle minute, 

 prominent and naked. 



The smallest and latest in flowering of our British species, as well as the most 

 aromatic, the odour of the fresh herb being equally pungent and agreeable with 

 that of Southernwood {A. Abrotanum).
