252 SCROPHULARIACE^. Antirrhinum. 



* Perennial Old World species. 

 A. mAjus, L. (Common Snapdragon.) A foot or two high: leaves thickish, from oblong 

 to linear, smooth : flowers short-pedicelled in a glandular-pubescent terminal raceme : 

 corolla li or 2 inches long, purple, rose, or white. — Sparingly escaped from gardens to 

 road-sides in Atlantic States. 



* * Indigenous Californian species, annual so far as the root is known, small-flowered: promi- 

 nent palate closing the orifice of the corolla ; its upper lip spreading and lobes of the lower usuall}' 

 deflexed : filaments dilated at their apex. — § Sceivrhinam, Gray, Proc. Am. Acad. vii. 372, but 

 a misnomer, the palate not gaping. 



-)— Erect, in no way climbing, destitute of prehensile brauchlets. 



++ Flowers racemose-spicate, mostly rose-colored : capsule surmounted by a slender style : seeds 

 fimbrillate-favose. 



A. virga, Gray. Glabrous throughout : root not seen : stem strict, simple, 2 or 3 feet 

 high : leaves thickish, linear-lanceolate ; the lower 2 or 3 inches long, often 3 lines wide ; 

 the upper passing into filiform-subulate bracts of the long virgate spiciform raceme : flow- 

 ers sometimes secund, soon horizontal: corolla with cylindrical tube (half inch long) fully 

 twice the length of the lips and of the ovate-lanceolate sepals ; sac at base mammajform : 

 filaments viscid-hirsute; the dilated tips of the longer pair broader than the anther: 

 capsules erect, ovoid, longer than the unequal sepals. —Proc. Am. Acad. vii. 373, & Bot. 

 Calif, i. 549. — \V. California, Bridrjes, in flower. Mendocino Co. in fruit, G. R. Vasey. 



A. glandulosum, Lindl. Very glandular-pubescent and viscid throughout : stem 

 stout, branching, 3 to 5 feet high, very leafy : leaves lanceolate, mostly sessile, above 

 gradually passing into bracts of the leafy dense spike or raceme ; these equalling or 

 shorter than the oblong tube of the corolla : sepals oblong-lanceolate, unequal ; the longer 

 equalling the capsule: filaments all moderately dilated upwards. — Bot. Reg. t. 1893; 

 Benth. in DC. Prodr. x. 291. — Dry ground, California, from Santa Cruz southward. 



++ ++ Flowers sessile or nearly so in the axils of all but the lowest almost uniform leaves : corolla 

 only 3 or 4 lines long, yellowish or dull purplish ; the lips nearly tlie length of the tube; the sac 

 prominent : sepals equal, linear, not longer than the ovate-globular capsule ; the whole style indu- 

 rated and persistent, stout at base. 



A. COrnutuin, Benth. Viscid-villous, simply branched, a foot or so high : leaves linear- 

 oblong or lanceolate, obtuse (an inch long) ; the lower tapering into a short petiole: fila- 

 ments all obliquely obovate-dilated at apex : style rather longer than the capsule : seeds 

 echinate-favose. — PI. Hartw. 328 ; Gray, Proc. Am. Acad. 1. c. — Valley of the Sacramento, 

 California, ILirtirefj. 



A. leptaleum, Gray, 1. c. Viscid-villous, mostly simple, a span or two high : leaves 

 nearly linear, mainly sessile (the lowest less than an inch long, uppermost small and spatu- 

 late-oblong) : shorter filaments hardly dilated at apex : style rather shorter than the cap- 

 sule : seeds rugose-pitted. — ^1. cornutum, Durand in Pacif. R. Rep. v. 11, t. 10, not Benth. 

 — California ; Sierra Nevada from Mariposa Co. to Kern Co. 



•i— -i— Spreading or erect, branching, producing filiform and at length tortile axillary branchlets 

 by which the plant is disposed to climb: calyx unequal: corolla (purple, violet, or yellowish- 

 white) short; both lips spreading, the lower usually conspicuously larger and as long as the tube. 



++ Flowers in a naked spike or dense raceme : bracts minute. 

 A. Coulterianum, Benth. Stem 2 to 4 feet high, gaining support by its numerous 

 filiform tortile branchlets acting as tendrils, below glabrous, as also the (from linear to 

 oval) distant leaves : inflorescence villons-pubescent with viscid and sometimes glandular 

 hairs; the spike virgate, 2 to 10 inches long: pedicels shorter than the calyx: sepals 

 linear or lanceolate, obtuse, the 3 upper a little longer, all shorter than the oval or ovate- 

 oblong glandular-pubescent capsule, which is twice the length of the style. — DC. Prodr. 

 X. 592; Gray, I.e. — Santa Barbara Co. to San Diego, California. Corolla either violet- 

 purple or white with yellowish palate; the lower lip with its great palate forming the 

 larger part of the flower; the tube only 3 lines long, its sac broad and mammiform. 

 Tendril-shoots mostly below, sometimes also in the lower part of the inflorescence. 



++ ++ Flowers (purple) scattered along the slender diffuse branches, or somewhat racemose but 

 Icafv-bracteate at the sunnnit, often accomi)anied by tortile prehensile branchlets from the same 

 axils : upi)er sepal conspicuously larger than the others : leaves short, from linear to ovate. 



:^ Peduncles shorter than the flower, mostly shorter than the calyx or hardly Awy: tube of the 

 corolla rather longer than the lips : seeds tiitjerculate.
