MINT FAMILY. 



101 



sacs divergent, only slightly confluent at the base. Ovary not deeply 4-lobed. Nutlets obovoid, 

 rugose-reticulate. [Greek, without a yoke; from the seeming absence of the upper lip of 

 the corolla.] 



About 40 species, natives of the Old World. Type species : Ajuga reptans L. 



Sparingly pubescent, or glabrous, stoloniferous. i. A. reptans. 



Pubescent with long hairs, not stoloniferous. 2. A. genevensis. 



i. Ajuga reptans L. Bugle. Fig. 3564. 



Ajuga reptans L. Sp. PI. 561. 1753. 



Perennial, sparingly pubescent or glabrous, 

 producing slender creeping stolons sometimes 

 i long; stem erect, rather stout, 6'-!$' tall. 

 Basal leaves tufted, obovate, rounded at the 

 apex, crenate or undulate, i'-3' long, tapering 

 into margined petioles; leaves of the stem ob- 

 long or oblanceolate, much smaller, sessile or 

 nearly so, those of the stolons mostly petioled ; 

 upper flower-clusters often forming a short 

 spike, the lower commonly distant and axil- 

 lary; corolla blue or nearly white, about i' 

 long. 



In fields, Quebec and Maine to southern New 

 York, locally naturalized from Europe. Brown 

 bugle. Middle comfrey. Carpenter's-herb. Sickle- 

 wort. May-June. 



2. Ajuga genevensis L. Erect Bugle. 

 Fig- 3565. 



Ajuga genevensis L. Sp. PI. 561. 1753. 



Perennial, not stoloniferous; stems usually sev- 

 eral from the root, ascending, rather stout, long- 

 pubescent. Leaves long-pubescent, the basal ones 

 long-petioled, spatulate or oblanceolate, obtuse, 

 sparingly toothed or entire, 2'-4' long, the upper 

 sessile, obovate to ovate, usually coarsely den- 

 tate, much smaller ; bracts pubescent, the upper 

 shorter than the flowers; inflorescence mostly 

 dense; corolla i'-!' long. 



In fields and waste grounds, Maine to New York 

 and Pennsylvania. Adventive from Europe. May- 

 July. 



2. TEUCRIUM [Tourn.] L. Sp. PI. 562. 1753. 



Herbs or shrubs, with dentate entire or laciniate leaves, and rather small pink, white or 

 purplish flowers, in terminal bracted spikes or heads, or verticillate in the upper axils. Calyx 

 tubular-campanulate, lO-nerved, equally or unequally 5-toothed. Corolla-tube short, the limb 

 irregularly s-lobed, the 2 short upper lobes oblong, declined or erect, the lateral lobe declined, 

 more or less united with the upper ones, the lower lobe broader, also declined. Stamens 4, 

 didynamous, exserted between the 2 upper lobes of the corolla, the anterior pair the longer; 

 anther-sacs divergent, confluent at the base. Ovary 4-lobed ; style 2-cleft at the summit. 

 Nutlets obovoid, rugose-reticulated. [Named from the Trojan king, Teucer.] 



Over 100 species, of wide distribution in temperate and tropical regions. Besides the follow- 

 ing, 2 or 3 others occur in the southern and southwestern United States. Type species : Teucrium 

 fruticans L.
