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 lches 

 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 

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

 stamens 1-celled (halved), of the upper 2-eelled 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. §. vea'SlcoiOJ', Nutt. Sift hairy, 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, 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, Aih'n, Wood.) 



2. S. saxsstiBiS, Riddell. Smoothish or slightly hairy; stem weak, ascend- 

 ing (6'- 18' long), often producing runners, branched ; leaves "rati' 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. 



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

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

 except in No. 6. 



3. §. csaaarscens, Nutt. Stem branched (2° -4° high), above, with the 

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

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

 soft down, 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 V long. 



4. S. SCM'&ta, 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 ; calyx, &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. §. l>Bldsa, Michx. Pubescent with spreading hairs; stem nearly sim- 

 ple (1° -3° high); 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
