314. LABIAT/E. (MINT FAMILY.) 



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

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

 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 tho 

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

 stamens 1-celled (halved), of the upper 2-celled and heart-shaped. Bitter pe- 

 rennial herbs, not aromatic, with axillary excise spiked or racemed flowers ; the 

 short peduncles chiefly opposite, 1-flowcred, often 1-sided. (Name from scutella, 

 a dish, in allusion to the form of the appendage to the fruiting calyx.) 

 * Flowers (blue) in terminal racemes; the floral leaves, except the lower ones, l*ing 



small, and reduced to bracts. 



- Lips short, nearly equal in lenath ; the lateral lobes rather distinct, and almost as 

 long as the strai(jhtlsh or scarcely incurved upper Up : leaves on slender petioles. 



1. S. vcrsicolor, Nutt. Soft hairy, the hairs of the inflorescence, c. 

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

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

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

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

 July. Corolla |' long, with a slender tube, below whitish, the lower lip purple- 

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

 as to the upper lip. S. saxatilis, var. ? pilosior, Benth., is probably a smaller 

 form of this, as is S. rugosa, Wood. (Harper's Ferry, Allan, Wood.) 



2. S. savfitilis, Riddcll. Smoothish or sll'jhtl;/ hainj ; stem weak, ascend- 

 ing (6'- 18' long), often producing runners, branched ; leaves ovate or ovate-oblong 

 and mostly heart-shaped, coarsely crenate-toothed (l'-2' long), ///?', obtuse; upper 

 bracts oblong or ovate, small; racemes loose. Moist shaded banks, 8. Ohio, 

 Virginia, and Kentucky, and southward in the mountains. June, July. Co- 

 rolla f long, the lateral lobes connected with the straightish upper lip. 



- - Lateral lobes of the corolla small, much shorter than the decidedly arched or 

 incurved up] xr lip, and connected with it: stem erect: leaves moderately pctloled, 

 except in No. 6. 



3. S. CillieSCCIlS, Nutt. Stem branched (2 -4 high), above, with the 

 panicled many-flowered racemes, JJoiccrs, and the, foirer surface of ikf. nratr or lanrc- 

 ovate acute (at the base acute, obtuse, or cordate) crcinit>- /><tr,s, irhifish ?rft/i jinc 

 sfl {f(ni, often becoming rather glabrous ; bracts oblong or lanceolate; upper 

 lip of the corolla shorter than the lower. Rich ground, Penn. to Illhnis and 

 southward. July. Corolla %' long. 



4. S. scrrsita, Andrew?. Grim atid nearly f/htJirwis ; stem rather simple 

 (l-3 high), with single loosely-flowered racemes; leaves serrate, acuminate at 

 both ends, ovate or ovate-oblong ; calyx, c. somewhat hairy ; '// of the corolla 

 t.ijna 1 in length (corolla 1' long, the tube more tapering below than in the last 

 which this resembles). Woods, Maryland, Illinois, and southward. July. 



5. S. pilosa, Michx. Pubescent trifh sprcadi'iiy hairs; stem nearly sim- 

 ple (1 -3 high) ; leaves rather distant, crenate, of>l>n(/-or<iti>, obtuse, varying to 

 roundish-ovate, the lower abrupt or heart-shaped at the base and long-petloled 

 the upper on short margined petioles, veiny ; bracts oblong spat ulate; racemes
