- - Corolla (8" -9" long), with a slender tube: lower Up large and rather longer 

 than the somewhat arched upper lip : stem simple. 



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 

 base ( 1' - 2' long). Wet shady places : common northward. (Eu.)

 high) ; leaves lanceolate-ovate or ovate-oblong, pointed, coarsely serrate, rounded

27. MABBUBIUM, 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

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

 like the lower ones. (Name composed of yaAf'i;, a weasel, and ttyis, resemblance, 

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