 foliage minutely tomeuto^e-caiieseent. 



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

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

 lower calyx-teeth subulate-setaceous. — Bot. Calif, i. 601. — Near Tighe's Ranch, mountains 

 north-east of Sun Diego, Palmer. 

 —A. Clevelandi, 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. 76, & Bot. Calif. I.e. — Jlotuitains behind San

++++++ Corolla barely half inch long; its tube hardly 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 : calj'x 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 thjTsoid-paniculate : floral leaves, bracts, and bractlets small 

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

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



A. polystachya, Benth. l. 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 -S-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^iego Co. JJne of th£ shrubs called Grease-wood. 



30. MON.^^DA, L. Hor^e-Mint. {Nicolas Monardes, early writer upon
