600 LABIATE. Audibertia. 



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

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

 Lower California, lat. 26°. It is related to S. eallot^efloka, 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-lohed or ernarginate ; the lower spreading 

 and 3-lobed, the broad middle lobe ernarginate. 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 iipper 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, mem- 

 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. 1 32, t. 38, the sterile filaments incorrectly 

 represented. 



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



* * Smaller-flowered : corolla from half to three fourths 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-spicafe or rarely solitary : corolla not over half cm 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 refuse, 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 ernarginate upper lip : stamens much exserted. 

 — Lindl. Bot. Beg. t. 1469. 



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

 the Upper Columbia Eiver. 



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.
