814 LABIATE, (mint family.) 



ing away. Corolla with an elongated curved ascending tnbe, 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 tlie 

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

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

 rennial herbs, not aromatic, with axillary or else spiked or raccmcd 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 fruithig calyx.) 

 * Flowers {blue) in terminal racemes ; the floral leaves, except the Iowa- ones, being 



small, and reduced to bracts. 



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



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°-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-haii-y caly.x ; ra- 

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

 July. — Corolla |' long, with a slender tube, below whitish, tlic lower lip puqilc- 

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

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

 form of this, as is S. nigosa. Wood. (Harper's Ferry, Aildn, Wood.) 



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

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

 andmostly heart-shaped, coarsely crenate-toothed (l'-2' long),(/!i«, 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 J' long, the lateral lobes connected with the straightish upper lip. 



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

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

 except in No. 6. 



3. S. canescens, Nutt. Stem branched (2° -4° high), above, witli the 

 panided many-flowered racemes, flowers, and the leaver siirfiice of the ovate or lance- 

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

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

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

 southward. July. — Corolla §' 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 ; calyx, &e. 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. pilosa, 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
