314 LABIATJE. (MINT FAMILY.) 



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

 throat, li-lipped ; the upper lip arched, entire or barely notched ; the lateral Icbes 

 mostly connected with the upper rather than the lower lip ; the lower lube or lip 

 spreading and convex, notched at the apex. Stamens 4, ascending under tho 

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

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

 rennial herb?, not aromatic, with axillary or else spiked or racemed flowers; tho 

 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 



KIII all, and reduced to bracts. 



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

 lony as the straiyhtish or scarcely incurved upper lip : hares on s/V ."</'/ j>< lioles. 



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

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

 orate, chiefly heart-shaped, crcnate-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 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. 1 pilosior, Benth., is probably a smaller 

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



2. S. Sax:fttiliS, Riddcll. Smoothish or slightly h airy ; stem weak, ascend- 

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

 and mostly heart-shaped, coarsely eremite-toothed (l'-2' long), thin, olrtuse; 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 ivith it : stem erect : leaves moderate /y / 

 except in No. 6. 



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

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

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

 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 ' long. 



4. S. serrfita, Andrews. Green and nearly glabrous j stem rather simple 

 (1-3 high), with single loosely-flowered racemes; leaves serrate, amm/nalc at 

 loth ends, ovate or ovate-oblong ; calyx, &c. somewhat hairy ; '// <>f t/ir corolla 

 eipia! in length (corolla 1' long, the tube more tapering below than in the last, 

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



5. S. pil<>Sl, Michx. Pubescent with spreadiiif/ hair.-i: stem nearly sim- 

 ple (1 -3 high) ; Irai'i-s rathd' distant, cr< nate, olilony-orali', tJ>htiu\ varying to 

 roundish-ovate, the lower abrupt or heart-shaped at the b:isc and long-petioled, 

 ihe upper on short margined petioles, veiny ; bracts oblong-sputulate; racemes
