* * * Corolla decidedly 1-lipped : calyx b-loudied, regular, or sometimes obscurely 

 2-lipj>ed, not i-lustiiy in fruit : the tctth commonly awl-shaped or triangular, 

 often rii/iil or spiny-tipped, 



T- Stamens included in the tube of the corolla : calyx 10-toothed. 



31. MARh'ri'.ir.M. Teeth of the calvx awl-shaped or spiney-tipped, recurved 



after flowering. Corolla small! upper lip erect. Bitter-aromatic plants: 

 flowers iu axillary capitate whorls. 



- f- Stamens raised out of the tube of the corolla : calyx b-toothed. 

 ** Anthers opt-niiiy crosswise by 2 unequal r/r< s, the smaller one ciliate. 



32. GALKOPSIS. Calvx tubular Ijell-shaped, 5-nerved, with spinv-tipped teeth. 



Corolla enlarged 'in the throat, the ovate and entire upper lip arched, the 

 middle lobe of spreading lower lip obcordate. Flowers in axillary whorl-like 

 clusters. 



*+ *-( Anthers opening lengthwise in the ordinary way. 



33. LAMIUM. Calyx tubular bell-shaped, with 5 awl-shaped spreading teeth. 



Corolla much enlarged in the throat, the upper lip arching and with a narrow 

 base, lateral lobes of lower lip very short, the middle one rounded and spread- 

 ing or turned down, its base much narrowed. (Lessons, p. 90, fig. 256.) 

 Mamcns ascending under the upper lip. Nutlets truncate at the top. 



34. LKONTBl'S. Calyx top-shaped, the awl-shaped teeth when old spreading and 



spiny-pointed. Corolla like Stachys, but middle lobe of lower lip obcordate. 

 Stamens parallel. Nutlets truncate and sharply 3-angled. Stems erect. 

 Flowers in close whorls in the axils of cut-lobed leaves. 



35. STACHYS. Calyx mostly tubular bell-shaped, the teeth triangular or awl- 



shaped, sometime* rigid fir even pungent. Corolla not enlarged in the throat, 

 the upper lip entire or nearly so, the lower 3-lobed with the middle lobe 

 nearly entire. Stamens ascending under the upper lip, but the outer pair 

 turned down after discharging their pollen! Nutlets obtuse, but not trun- 

 cate. Flowers crowded in whorls, most of these commonly approximate in a 

 terminal raceme or spike. 



36. BETOXICA. Like Stachys, but calyx more tubular and with awn-like teeth, 



tul ie of corolla longer and its upper lip sometimes notched, and the stamens

38. MOLUCCELLA. Calyx membranaceous and greatly enlarged, funnel-form, 



the bonier reticulated, veiny, entire, except 5 mucronate points. Corolla 

 much shorter than the calyx; the middle lobe of its lower lip obcordate. 

 Nutlets 3-sided.

T. Canadense, our only species, in low grounds, 1 -,'J high, downy, 

 with ovate-lanceolate serrate leaves downy beneath, and pale purple or rarely 

 white tlowers collected in a long spike, in late summer. 



. 2. TRICHOSTEMA, BLUE CURLS. (Name from the Greek, means

 lierb>, with entire leaves, ami small (lowers as it were panicled, blue, or 

 changing to purple, iu summer and autumn. (T) 



T. dichdtomuin, COMMON B. or BASTARD PKXNYKOY.U.. Sandy fields 

 K. & S. : i','- \-2' high, with mostly lance-oblong sliort-petioled leaves. 



T. lineare, from New Jersey S., has linear or lance-linear smoother leaves. 



3. ISANTHUS, FALSK PKNNYROYAL. (Name in Greek means equal 

 _rlon;r, i. e. parts of corolla regular.) (T) 



I. CCeruleus. Common in sandy or sterile soil ; bushy-branched, clammy- 

 pubescent, 6' - 12' high, with oblong 3-ncrvcd entire leaves, and scattered small 

 Uue (lowers on axillary peduncles : all summer.
