Dicliptera. LABIATjE. 589 



slender-petioled: 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 with a short blunt spur : capsule tomen- 

 fcose, club-shaped, the stalk-like empty base longer than the seed-bearing portion. — 

 Lot. Sulph. 38. Jacobiaia Californica, Xees in DC. Prodr. xi. 729. Sericographis 

 Californica, Gray in Bot. Mex. Bound. 125. 



Along the southeastern borders of the State (Fremont, Newberry, Parry, &c.), in Arizona, and 

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

 the base. 



4. DICLIPTERA, Juss. 



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

 the upper lip interior in the bud, flat or concave, emarginate 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 seedless and stalk-like : the strong processes that bear the s?eds curving 

 upward and becoming hook-like at dehiscence. Seeds Hat. — Mostly In rlis; with G- 

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

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



1. D. resupinata, -Tuss. Nearly glabrous: stems slender, loosely branching: 

 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. 12o. D. thlas- 

 pioides, Nees in DC. 1. c. -174. 



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

 California, in the form of Ih thlaspioidcs ; so called because the Battened pair of bracts (8 to ."i 

 lines in diameter), terminating a peduncle of about tin- same length, may lie likened to tin' silicic 

 of a Tltl<i.</,)'. In most species, when the Bowers 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, opposite simple leaves 



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



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



bottom of tie- 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 -1 in the upper and one in the lower lip). Stamens on the 



< '"I f the corolla, Style 2-clefl at the apex, often unequally so, or one of the lobes 



obsolete: 3tigmas minute. Seed erect from the bus.- of the nutlet, mostly without 



albumen. Embryo straight (except in Sr„t, //</>■<',/) ; the radicle inferior. — Foliage 



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



the aroma an. I warm pungency of a large pari of the order. inflorescence axillary, 



the Sowers when clustered cymose, tho cymes, clusters, Ac., sometimes racemose or 



Bpicate at the upper portion of the stem or 1. ranches.
