 Hairy Scutellaria, Vulgo— Scull-cap. 



Root perennial. &tm 12 to 18 inches high, more or less hairy, often purplish. 

 uZsZ to 5 distant pairs, 1 to 2 and a half inches long, and 3 fourths of an inch 

 to an inch and half wide, rhombic-ovate, cuneately tapering to a petiole* ;*£ 

 more or less pubescent, punctate beneath, the lower ones obtuse, those above 

 rather acute. Raceme terminal, generally simple and few-fiowered ; pedicels hir- 

 sute ; bracts elliptic, entire, tapering to a petiole at base, hirsute and cilia te, pun* 

 tate beneath. Calyx hirsute. Corolla purplish blue at summit, with .the tube 

 nearly white, pubescent externally, half an inch to 3 quarters in length. 

 Hob. Open woodlands ; borders of thickets : common. Fl. June-Aug. Fr. Aug-Sept. 



Obs. This species affords some striking varieties. I have specimens from the 

 Susquehanna, with broad elliptic leaves, nearly twice the size of ours, smooth and 

 membranaceous, and on longer petioles. 



2, S, ixtegiiifolia, L. Stem erect, nearly simple, pubescent ; leaves 

 oMong-Ianceolate, or sublinear, entire, rather obtuse, on short petioles ; 

 racemes terminal, subpaniculate, loose, leafy ; bracts lanceolate ; flowers 

 large. Beck, Bot. p % 282.

Extire-leaved Scctellaiua. Vulgo— Large-flowered Scull-cap. 



Root perennial. Stem 1 to 2 feet high, rather slender, clothed with a short fine 

 pubescence, greyish green, sparingly branched above, the axils below often with 

 short slender abortive branches bearing a tuft of small leaves. Leaves 1 to 2 inches 

 long, and 1 fourth to 2 thirds of an inch wide, minutely pubescent, pale green or 

 cinereous, tapering at base to a short petiole. Racemes terminal and subterminal, 

 loose; branches and pedicels densely hoary-pubescent; bracts oblong-lanceolate, 

 subsessile, pubescent. Calyx pubescent, the galeate appendage becoming large. 

 Corolla bright blue at summit, with the tube paler (or nearly white), pubescent ex- 

 ternally^ fourths of an inch to an inch long, the limb and throat much dilated. 

 Akenes subglobose, tuberculate, dark brown. 

 Hab. Moist thickets, and meadows: frequent. Fl. June— July. Fr. Aug— Sept. 



Obs. This species is readily known by its handsome large flowers, and narrow 

 oblong entire leaves. It is intensely bitter; and, no doubt, might be usefully em- 

 ployed as a tonic. 



3. S. parvcla, Mx. Stem decumbent, or oblique, slender, branching 

 from the base, minutely pubescent ; leaves ovate, or lance-ovate, mostly 

 entire, subcordate at base, sessile or subsessile ; flowers small, axillary, 

 solitary, opposite. Benth. Lab. p. 440.
