 lower shorter, 2-toothed. Corolla 2-lipped ; upper lip notched ; the lower much 

 larger, 3-lobed. Stamens included. Style slender : stigma 2-lobed. Fruit dry, 

 in the bottom of the calyx, oblong, 1-celled and 1-seeded ! Seed orthotropous. 

 Radicle pointing upwards : cotyledons convolute round their axis. — A peren- 

 nial herb, with slender branching stems, and coarsfily toothed ovate leaves, the 

 lower long-petioled ; the small opposite flowers in elongated and slender terminal 

 spikes, reflexed in fruit, and bent close against the axis. Corolla purplish or 

 pale rose-color. (Derivation of the name unknown.)

Order 71. L,ABIAT.aE:. (Mint Family.) 



Chiefly herbs, with square stems, oppositejaxsmatic leapes, mpre or less 2- 

 lipped corolla, didynamous or diandrous stamens, and a deeply i-lohed ovary, 

 which forms in fruit 4 liitle seed-like nutlets or achenia, surrounding the base 

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

 gle erect seed. ^ Nutlets smooth or barely roughish and ft^ed by then- 

 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. (More abundant in the Old World 

 than the New. One third of our genera and many of the species are 

 merely introduced plants.)
