314 LABIATE. (MINT FAMILY.) 



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 lover 

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

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

 short peduncles chiefly opposite, 1-flowered, 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, being 



small, and reduced to bracts. 



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

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



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

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

 ovate, chiefly heart-shaped, crcnate-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., 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, Aikin, Wood.) 



2. S, Saxdtilis, Rid dell. Smoothishor slightly hairy ; 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), thin, obtuse; upper 

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

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

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



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

 incurved upper lip, and connected with it : stem erect : leaves moderately pctiolcd, 

 except in No. 6. 



3. S. CtlieSCC3l, Nutt. Stem branched (2 -4 high), above, with the 

 panicled many-flowered racemes, flowers, and the lower surface of the ovate or lance- 

 ovate acute (at the base acute, obtuse, or cordate) crenate leaves, whitish with flue 

 soft doivn, often becoming rather glabrous ; bracts oblong or lanceolate ; upper 

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

 southward. July. Corolla f ' long. 



4. S. serrata, Andrews. Green and nearly glabrous ; stem rather simple 

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

 both ends, ovate or ovate-oblong ; calvx, &c. somewhat hairy ; lips of the corolla 

 equal 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. |>i!6sa, Michx. Pubescent with spreading hairs; stem nearly sim- 

 ple (l-3high); leaves rather distant, crenate, oblong-ovate, obtuse, varying to 

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

 the upper on short margined petioles, veiny ; bracts oblong-spatulate ; racemes
