 branching, especially at the base, hairy at summit and on the angles, smooth ish 

 below, mostly purplish brown. Leaves 1 to 3 inches long, and half an inch to an 

 inch and half wide, variously toothed, or serrate, sometimes nearly entire, raroly 

 laciniate, somewhat hairy and ciliate ; petioles half an inch to 2 inches long (those 

 of the radical or lower leaves often 3 or 4 inches long), hairy. Flowers in term- 

 inal oblong compact imbricated spikes 1 to 3 inches in length ; bracts orbicular- 

 cordate, or subreniform, with a short abrupt acumination, hairy and ciliate, sessile, 

 the lower ones conspicuously acuminate. Calyx subseesile, hairy at base, lips

Hob. Woodlands ; roadsides, &c. common. Fl. July— Sept. fV. Aug— Nov. 



Obs. This plant is very common, here ; but Mr. Nuttall thinks i« is certainly 

 introduced. Its reputation, as a medicinal plant, is quite obsolete. Although 

 presenting some varieties, there is probably but the one species in the U. States. 



284. SCUTELLARIA. L. Mutt. Gen. 516. 

 [Latin, Scutella, a dish ; from the form of the appendage to the calyx.] 



Calyx campanulate, bilabiate, finally dividing to the base ; lips entire, 

 the upper one with a galeate appendage on the back, deciduous. Col 

 rolla bilabiate ; upper lip vaulted, lower one dilated, convex ; tube much 

 exserted, ascending from near the base. Stamens ascending under the 

 upper lip of the corolla ; anthers approximated in pairs, subcordate, vil- 

 lose-ciliate. Style unequally bidentate at apex. Akenes tuberculate. 



1 . S. pilosa, Mx. Stem erect, mostly simple, hairy-pubescent ; leaves 

 rhombic-ovate, or oval, crenate-serrate, petiolate, in distant pairs ; ra- 

 ceme terminal, rather short ; bracts elliptic-ovate. Jieck, Hot. p. 282.
