 or pointless. River-banks, N. J. to s. Ont. and Minn., s. to 

 Fla. and Tex. May-Sept. FIG. 881. 



2. L. nodiflbra (L.) Michx. Similar, but more depressed, 

 cinereous or greenish ; leaves blunter and more spatulate ; corolla 

 rose-purple or white. Mo. to N. C. and Tex. May-Sept. 

 FIG. 882. 



3. L. cuneifblia (Torr.) Steud. Diffusely branched from a

x %. throughout; leaves rigid, cuneate-linear, incisely 2-6-toothed 



above the middle ; peduncles axillary, often shorter than the 

 leaves; bracts rigid, broadly cuneate, abruptly acuminate; corolla pale. 

 Plains, Neb., Kan., and westw. May-Sept. 



3. CALLICARPA L. 



Calyx 4-5-toothed. Corolla tubular-bell- 

 shaped, 4-5-lobed, nearly regular. Stamens 4, 

 nearly equal, exserted ; anthers opening at the 

 apex. Style slender, thickened upward. 

 Shrubs, with scurfy pubescence, and small 

 flowers. (Name formed of KdXXos, beauty, and 

 Kopir6s, fruit.) 



1. C. americana L. (FRENCH MULBERRY.) 

 Leaves ovate-oblong with a tapering base, acu- 

 minate, toothed, whitish-tomentose beneath;

 corolla bluish; fruit violet-color. Rich soil,

LABlATAE (MINT FAMILY) 



Chiefly herbs, ordinarily with square stems, opposite aromatic leaves, more or 

 less 2-lipped corolla, didynamous stamens or these only two, and a deeply 4-lobed 

 ovary, which forms in fruit 4 little seed-like nutlets or achenes, surrounding the 

 base of the single style in the bottom of the persistent calyx, each filled with a 

 single erect seed. Nutlets smooth or barely roughish and fixed by their base, 

 except in the first tribe. Albumen mostly none. Embryo straight (except in 

 Scutellaria) ; radicle at the base of the fruit. Upper lip of the corolla 2-lobed 

 or sometimes entire ; the lower 3-lobed. Stamens inserted on the tube of the 

 corolla. Style 2-lobed at the apex. Flowers axillary, chiefly in cymose clusters, 

 these often aggregated in terminal spikes or racemes. Foliage mostly dotted 

 with small glands containing a volatile oil, upon which depends the warmth and 

 aroma of the plants of this large and well known family. 



I. Nutlets rugose-reticulated, attached obliquely or ventrally ; ovary merely 



4-lobed. 



Tribe I. AJU"GEAE. Stamens 4, ascending and parallel, mostly exserted from the upper side ol 



the corolla. Calyx 6-10-nerved. 



* Limb of corolla irregular, ceemingly nnilabiate, the upper lip being either split down or very 

 short ; stamens exserted from the cleft. 



1. Ajuga. Corolla with a very short and as If truncate upper lip. 



2. Teucrium. Corolla deeply cleft between the 2 small lobes of the upper Hp. 



C. americana x %.
