slender-potiolcd : racemes short and loose : bracts and bractlets deciduous : calyx- 

 lobes subulate : corolla dull red, narrow, an inch long ; the lips truncate : cells of 

 the anther nearly equal in size, the lower witli a short blunt spur : capsule tomen- 

 tose, club-shaped, the stalk-like empty V)ase lonjrpv than the seed-bearing portion. —

Along the southeastern borders of the State (Fre/)wnt, Neivberry, Parry, kc), in Aiizona, and 

 through Lower California. Capillary style rather persistent, at length separating by a joint above 

 the base. 



4. DICLIPTERA, Juas. 



Bracts a pair, valvately enclosing 1 to 3 flower-buds. Corolla tubular, bilabiate ; 

 the upper lip interior in the bud,. flat or concave, eniarginate or entire ; the lower 

 spreading, 3-toothed or lobed. Stamens 2 : anthers with 2 cells, one higher than 

 the other, both pointless. Capsule short, flattened contrary to the partition, 4-seeded, 

 the base floodloss and stalk-liko : the strong . procossos that boar the seeds curving 

 upward and becoming hook-liko at doliiscoiico. Seeds flat. — Mostly herbs ; with 0- 

 anglod stems, broadish and petioled leaves, and cither scattered or clustered flowers : 

 mainly tropical, two or three species reaching the United States. 



1. D. resupinata, Juss. Nearly glabrous : stems slender, loosely brandling : 

 leaves oblong or lanceolate, slender-petioled : peduncles scattered, bearing a pair of 

 cordate or rounded foliaceous bracts, and between them a single flower or rarely a 

 pair : corolla purplish, half an inch long. — Torr. Bot. Mex. Bound. 125. J), thlns- 

 pioides, Nees in DC. 1. c. 474. 



California, No. 557, Coulter : but perhaps only in Arizona, where it abounds, as also in Lower 

 California, in the form of D. thlmpioidcs ; so called because the flattened pair of bracts (3 to 5 

 lines in diameter), terminating a peduncle of about the same length, may be likened to the silicle 

 of a Thlaspi In most species, when the flowers are in clusters, many of the corollas appear to 

 be reversed (resupinate), the 3-lobed lip seemingly the upper one as respects the main axis. 



Order LXXIII. LABIATE. 



Herbs, or chiefly so, mostly aromatic, with square stems, o})posito simple loaves 



and no stipules, bilabiate corolla, didynamous or diandrous stamens, and an ovary 



parted into 4 lobes around the single style, forming 1-seeded seed-like nutlets in the 



bottom of the persistent calyx. — Flowers perfect. Calyx 3 - 5-toothed or cleft, or 



bilabiate. Upper lip of the corolla 2-lobed or entire ; the lower 3-cleft or parted 



(or in the first tribe as if 4 in the upper and one in the lower lip). Stamens on the 



tube of the corolla. Style 2-cleft at the apex, often unequally so, or one of the lobes 



obsolete : stigmas minute. Seed erect from the base of the nutlet, mostly without 



albumen. Embryo straight (except in Scutellaria) ; the radicle inferior. — Foliage 



mostly dotted with impressed glands, producing the volatile oil upon Avhich depends 



the aroma and warm pungency of a large part of the order. Inflorescence axillary, 



the flowers when clustered cymose, the cymes, clusters, &c., sometimes racemose or 



spicate at the upper portion of the stem or branches. 



A largo order, found in nil countries, but most abundnnt in wann-tcnqicnito rr;jioiis. All tlio 

 plants innocent, but some aroniatic-]iungcnt ; several used in medicine or for condiments; otliei's, 

 with brilliant blossoms, such as Mexican and nrazilian Snfjcs, ciiltivnted for ornament. Many 

 Old-World species, such as Marjoram, Savory, Thyme, several Mints, Cat-Mint, Motherwort, &c., 

 are naturalized in the Atlantic States, b\it have not been met with on the Californlan side.
