R. I'lATYCiiElLA, Gray, Pioc. Am. Acad. viii. 292, a shrulihy and hoary liluish-flowered species, 

 tlio luuiiolforin dilatud caly.x with ovato lips, was discovered hy 7>r. Palmer, at Caniieii Island, 

 Lower Calilornia, lat. 20'. It is related to S. liALLoTiKi'LOKA, Iknth., of New Me.vico and

11. AUDIBERTIA, Uenth. 

 Calyx nearly as in Salvia, or more cleft ou the lower siile, as if spulhaceous. 

 Corolla with the upper lip spreading, 2-lobed or einarginate ; the lower spreading 

 and 3-lobed, the l)roiid middlo lobe oiuarginato. Stamens 2 : filaments slender, ox- 

 sorted, apparently simple and bearing a linear ono-collod anther, or with an articula- 

 tion, showing tliat the portion above it answers to a liliform connective, the lower 

 end of wliich sometimes projects into a subulate point, but never shows any trace of 

 a second anther-cell. Vestiges of the posterior stamens often present. Perennial 

 aromatic herbs or undershrubs (all Californian extending into the regions adjacent), 

 hoary ; witli rugose-veiny mostly crenulato leaves, resembling those of Sage, and 

 capitate-glomerate or sometimes a more open and paniculate inflorescence : the 

 liowei-s prized for bees. 



§ 1. Flowers J tiisely capitate-ylomerate : bracts crowded and conspicuous. 



* Large: corolla an inch and a half long, a-imson-purple ; its npptr lip rather erect 



and short : lowei- leaves cordate or hastate at base. 



1. A. grandiflora, Benth. Stem villous and glandular, stout, 1 to 3 feet high 

 from a scarcely wooily base : leaves very rugose, sinuately crenate, white-tomentose 

 beneath ; the lower hastate-lanceolate and obtuse, 3 to 8 inches long, on margined 

 petioles ; the ui)per oblong and sessile ; floral ones and bracts broadly ovate, mem- 

 branaceous, villous, cuspidate-tipped : lieada large, interruptedly spicate : stamens 

 much exserted : ii conspicuous slender tooth representing the lower fork of the 

 connective. — Torr. Jiot. Mux. Hound. 13'J, t. 38, the sterile filaments incorrectly 

 re])roscuted. 



On the Coast lliuiges, lioni San Mateo Co. southward. A sliowy plant. 



* * Smaller-jloivered : corolla from half to three fourths of an inch long, violet or 



bluish-purple: leaves not cordate. 



-t- Jh-acts, most of tlii' jloral leaves, and the bilabiate calyx scarious-membranaceous, 

 reticulated, more or less colored; the tip obtuse, jmintless, or at most mucronate: 

 dense heads interrupted-spicate or rarely solitary : corolla not over half an inch 

 long : low species of the interior arid region. 



2. A. incana, Benth. Shrubby, a foot or so in height, finely tomentose-canescent, 

 leafy : leaves sputulatc or obovate, obtuse or retuse, entire, not rugose, glandular-dot-

 upper floral leaves obovate or oval, tlie innermost spatulate, pubescent and ciliate, 

 tinged with rose or purple : calyx turbinate, its ovate or oblong anterior teeth nearly 

 equalling the very broad truncate and cmarginate upper lip: stamens much exserted.
