25. BRTJNELLA, Tourn. (Prunella, Z.) Self-heal. 



Calyx tubular-bell-shiiped, soiiicwluit lO-nervud and reticuhitcd-veiny, flat- 

 tened on the upper side, naked in tlie throat, closed in fruit, 2-lipiJcd ; the up- 

 per lip broad and flat, truncate, with 3 .short teeth ; the lower 2-clett. Corolla 

 ascending, slightly contracted at the tlnoat, and dilated at the lower side just 

 beneath it, 2-lipped ; the upper lip erect, arched, entire ; the lower reflexcd- 

 spreadiug, 3-cleft ; its lateral lobes oblong ; the middle one rounded, concave, 

 crenulatc. Stamens 4, ascending under the upper lip : fllaments 2-toothed at 

 the apex, the lower tooth bearing the anther. Anthers approximate in pairs, 

 their cells diverging. — Low perennials, with nearly simple stems, and 3-flow- 

 ered clusters of flowers sessile in the axils of round and bract-like membrana- 

 ceous floral leaves, imbi'icated in a close spike or head. (Name said to be taken 

 from the German braune, a disease of the throat, for which this plant was a 

 reputed remedy. 



2. B. vulgaris, L. (Common Si;lf-iieal or He.vl-all.) Leaves ovate-

2 6. SCUTELLARIA, L. Skullcap. 



Calyx bell-shaped in flower, 2-lippcd ; the lips entire, closed in fruit, the upper 

 with a helmet-like at length concave and enlarged appendage on the back (the 

 upper sepal) ; calyx splitting to the base at maturity, the upper lip usually fall- 

 ing away. Corolla with an elongated curved ascending tube, dilated at the 

 throat, 2-lipped ; the upper lip arched, entire or barely notched; the lateral 

 lobes mostly connected with the upper rather than the lower lip ; the lower lobe 

 or lip spreading and convex, notched at the apex. Stamens 4, ascending under 

 the upper lip : anthers approximate in pairs, ciliate or bearded ; those of the 

 lower stamens 1-cclled (halved), of the upper 2-cellcd and heart-shaped. — Bit- 

 ter perennial herbs, not aromatic, with axillary or else s])iked or racemcd flow- 

 ers; in summer: the short peduncles or pedicels chiefly opposite, 1-flowered, 

 often 1 -sided. (Name from scutella, a dish, in allusion to the form of the ap- 

 pendage to the fruiting calyx.) 



* Flowers (blue) in terminal {single or pan id ed) racemes; the Jloral Icares, except the 



loiver ones, being small, and reduced to bracts. 

 1- Lips short, nearhj equal in length, the lateral lobes rather distinct, and almost as 

 long as the slraigldish or scarcely incurved upper lip : leaves on slender petioles. 

 1. S. versicolor, Nutt. Soft hairg, the hairs of the inflorescence, &c. 

 partly viscid-glandular ; stem mostly erect (l°-3° high); leaves ovate or round- 

 ovate, chiefly heart-shaped, crenate-toothed, very veiny, rugose, the floral reduced 

 to broadly ovate entire bracts about equalling the glandular-hairy calyx ; ra- 

 cemes mostly simple. — River-banks, &c., Pcnu. to Wisconsin and southward. 

 — Corolla 9" long, with a slender tube, below whitish, the lower lip purple- 

 spotted ; the upper deep blue ; the lateral lobes belonging as much to the loweif
