314 LABIATJE. (MINT FAMILY.) 



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

 throat, 2-lippcd; 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, eiliate or bearded ; those of the loucr 

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

 rennial herbs, not aromatic, with axillary or else spiked or racemcd 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 terniiml racemes; the floral leaves, except the lower ones, being 



ttndU, 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. versicolor, 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, crenate-toothcd, 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 f ' 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. sax&tilis, Riddell. Smoothishor slightly harry ; stem weak, ascend- 

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

 and mostly heart-shaped, coarsely crenate-toothed (!' 2' long), <Azn, 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 arched or 

 incurved upper Up, and connected, with it : stem erect : leaves moderately petioled, 

 except in No. 6. 



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

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

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

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

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

 southward. July. Corolla ' long. 



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

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

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

 equal in length (corolla 1' long, the tiibe more tapering below than in the last, 

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



5. S. pilosa, Michx. Pubescent with spreading hairs; stem nearly sim- 

 ple (1 -3 high) ; leaves rather distant, crenate, oblona-ovate, obtuse, varying to 

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

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