9. S. galericulata, L. Smooth or a little downy, erect (l°-2° high) ; 

 leaves ovate-lanceolate, acute, serrate, roundish and slightly heart-shaped at the 

 hase (l'-2'loag). — Wet shady places : common northward. (Eu.)

27. MARHUBIUM, L. Horehound. 



Calyx tubular, 5 - 10-nerved, nearly equally 5 - 10-toothed ; the teeth more or 

 less spiny-pointed and spreading at maturity. Upper lip of the corolla erect, 

 notched ; the lower spreading, 3-cleft, its middle lobe broadest. Stamens 4, 

 included in the tube of the corolla. Nutlets not truncate. — Whitish-woolly bitter- 

 aromatic perennials, branched at the base, with rugose and crenate or cut leaves, 

 and many-flowered axillary whorls. (A name of Pliny, said to be derived from

 fringed, the outer one larger and naked. — Annuals, with spreading branches, 

 and several - many-flowered whorls in the axils of floral leaves which are nearly 

 like the lower ones. (Name composed of yaXer), a weasel, and tyis, resemblance, 

 from some fancied likeness of the corolla to the head of a weasel.)
