600 LABIAT^E. Audibertia. 



S. r-LATYCHEiLA, Gray, Proc. Am. Acad. viii. 292, a shrubby and hoary bluish-flowered species, 

 the funnelform dilated calyx with ovate lips, was discovered by Dr. Palmer, at Carmen Island, 

 Lower California, lat. 26. It is related to S. BALLOT^EFLORA, Benth., of New Mexico and 

 Texas. 



11. AUDIBERTIA, Benth. 



Calyx nearly as in Salvia, or more cleft on the lower side, as if spathaceous. 

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

 and 3-lobed, the broad middle lobe emarginate. Stamens 2 : filaments slender, ex- 

 serted, apparently simple and bearing a linear one-celled anther, or with an articula- 

 tion, showing that the portion above it answers to a filiform connective, the lower 

 end of which 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 ; with rugose-veiny mostly crenulate leaves, resembling those of Sage, and 

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

 flowers prized for bees. 



1. Flowers densely capitate-glomerate : bracts crowded and conspicuous. 



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



and short : lower leaves cordate or hastate at base. 



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

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

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

 petioles ; the upper oblong and sessile ; floral ones and bracts broadly ovate, rueni- 

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

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

 connective. Torr. Bot. Mex. Bound. 132, t. 38, the sterile filaments incorrectly 

 represented. 



On the Coast Kanges, from San Mateo Co. southward. A showy plant. 



* * Smaller-flowered : corolla from half to three fourt/ts of an inch long, violet or 



bluish-purple : leaves not cordate. 



-{- Bracts, most of the, floral leaves, and the bilabiate calyx scarious-membranaceous, 

 reticulated, more or less colored; the tip obtuse, pointless, 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 spatulate or obovate, obtuse or retuse, entire, not rugose, glandular-dot- 

 ted, seldom an inch long, all but the uppermost tapering into a petiole : bracts and 

 upper floral leaves obovate or oval, the 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 emarginate upper lip : stamens much exserted. 

 Lindl. Bot. Reg. t. 1469. 



From San Diego Co. along the eastern borders of the State, and from S. Utah northward to 

 the Upper Columbia River. 



3. A. capitata, Gray. Cinereous-pubescent : leaves oblong, acutish, very rugose, 

 crenulate, somewhat abruptly petioled : flowers usually in a single terminal head : 

 bracts and floral leaves apparently whitish, ovate or oval, minutely glandular : other- 

 wise resembling the preceding. Proc. Am. Acad. vii. 387.
