Audibertia. LABIATE. 373 



tapering into a slender petiole ; the mostly inconspicuous floral ones and the bracts vil- 

 lous, membranaceous, ovate-lanceolate and lanceolate : calyx distinctly bilabiate but 

 rather more deeply cleft between the anterior teeth ; these and the 3 teeth of the ample 

 concave upper lip subulate but not rigid ; lower lip of the corolla crenulate-erose : stamens 

 and style long-exserted : connective continuous with the filament. From the Yuba River 

 to San Diego Co., but rare. 



A. stachyoides, Bentll. 1. c. Shrubby, branching and leafy, a yard or more high, 

 cinereous-tomentulose or glabrate, rigid: leaves somewhat less rugose than in the last, 

 more crenate, oblong-lanceolate, narrowed at base or short-petioled ; the floral and ovate 

 or oblong bracts with the teeth of the bilabiate calyx cuspidate-acuminate or spinulose- 

 aristulate (rarely almost muticous) : style and especially the stamens little exserted : sub- 

 ulate appendage of connective often manifest. From San Francisco Bay to the southern 

 borders of the State: forming thickets. 



H- -w- Corolla from two-thirds to three-fourths inch long, with tube much surpassing the calyx and 

 short more or less pointed thinnish bracts: upper lip of the calyx 1-3-mucronate ; teeth of the 

 lower cuspidate : stamens and style moderately exserted : stems woody below, 4 to 8 feet high, 

 with herbaceous long and viniate branches : glomerules rather large, scattered or rather distant : 

 foliage minutely tomentose-canescent. 



A. Palmeri, Gray. Leaves oblong-lanceolate, acute (not unlike those of the preceding 

 species), the larger 2 or 3 inches long: verticillastrate heads several (4 to 8) and remote in 

 the elongated virgate spike : bracts oblong or lanceolate, slender-cuspidate or acuminate: 

 lower calyx-teeth subulate-setaceous. Bot. Calif, i. G01. Near Tighe's- Ranch, mountains 

 north-east of San Diego, Palmer. 



A. Cleveland.!, Gray. Leaves oblong, or the upper lanceolate-oblong, all obtuse, sel- 

 dom over an inch or so in length : heads fewer, often solitary or terminating short axillary 

 branches : bracts ovate or oblong, mucronate or abruptly short-pointed, viscid-pubescent, 

 as is the calyx; the lower teeth of which are short and subulate, the upper lip entire and 

 cuspidate-tipped. Proc. Am. Acad. x. 70, & Bot. Calif. 1. c. Mountains behind San 

 Diego, Cleveland, Palmer. 



-H- -H- -H- Corolla barely half inch long: its tube hardlv exceeding the herbaceous obtuse and 

 muticous bracts and calyx teeth: whole plant hoary-white. 



A. nivea, Bentll. Canescent with a close white-farinose tomentum, 3 or 4 feet high, 

 shrubby below, leafy: leaves oblong-lanceolate, or the lowest ovate, obtuse; upper with 

 truncate base, very short-petioled : bracts oval or oblong : calyx splitting down anteriorly, 

 at length emarginate posteriorly : corolla light-purple : stamens and style much exserted : 

 connective almost continuous with the filament. Lab. 313 & DC. 1. c. Dry hills, from 

 Santa Barbara to San Diego Co. 



2. Inflorescence thyroid-paniculate: floral leaves, bracts, and bractlets small 

 and loose, at length re flexed, lanceolate or subulate, cuspidate-tipped : corolla with 

 ample lower lip twice the length of the upper ; the tube very short. 



A. polystachya, Beilth. 1. c. Shrubby, 3 to 10 feet high, minutely tomentose-canes- 

 cent : branches and elongated naked thyrsus virgate : leaves mostly very white, oblong-lan- 

 ceolate, minutely rugose and crenulate, 2 or 3 inches long : flowers subsessile, loose : upper 

 lip of the calyx truncate or 3-toothed, at length concave or galeate, longer than the trian- 

 gular-subulate lower teeth : corolla pale or white ; lower lip half inch and tube quarter 

 inch long : style and divergent stamens long-exserted : filiform connective continuous with 

 the filament, its lower end usually indicated by a minute tooth. Arid hills, Santa Bar- 

 bara to San Diego Co. One of the shrubs called Grease-wood. 



30. MONARDA, L. HORSE-MINT. (Nicolas Monardes, early writer upon 

 American medicinal plants.) -- Aromatic erect herbs (of Atlantic N. America, 

 reaching to the Rocky Mountains), usually tall; with the large verticillastrate-capi- 

 tate glomerules single, or as if proliferous-spicate, or in upper axils, and involu- 

 crate by numerous sometimes colored outer bracts and floral leaves : flowers rather 

 large, in summer. (Gray, Proc. Am. Acad. viii. 369.)
