636 MENTHACEAE 



15. SALVIA [Tourn.] L. Sp. PI. 23. 1753. 



Aromatic herbs or shrubs, with clustered often showy flowers arranged in more or 

 less interrupted spikes or less commonly in racemes or panicles. Calyx ovoid, tubular or 

 campanulate, 2-lipped ; upper lip entire or 3-toothed ; lower lip 2-cleft or 2-toothed ; or the 

 lips and teeth entirely suppressed and the orifice very oblique and entire. Corolla strongly 

 2-lipped; upper lip usually concave or arched, entire, emarginate or 2-lobed; lower lip 

 spreading or drooping, 3-lobed. Stamens 2, the posterior pair wanting or rudimentary, 

 inserted on the throat of the corolla; anther-connective elongate, articulate with the fila- 

 ment and often equaling or exceeding it in length, both ends of the connective prolonged 

 and bearing a fertile pollen cell at each end, or the lower arm completely suppressed or 

 rudimentary and sterile. Style 2-cleft at the summit; ovary deeply 4-parted. Nutlets 

 smooth, in some species developing mucilage and spiral tube when wetted. [The ancient 

 Latin name for sage.] 



A large genus of over 500 species, widely distributed in temperate and tropical regions but especially highly 

 developed in South America. Type species, Salvia officinalis L. 



Lower end of the anther-connective prolonged beyond the articulation with the filament and bearing an anther- 

 cell at the tip. 

 Annual herbs. 



Flowers yellow, scattered in ample panicles; leaves scattered, irregularly lobed and toothed; herbage 



densely arachnoid. 1- S. Aethiopsis 



Flowers lavender or blue, in large capitate verticils, these solitary or forming an interrupted spike; 

 leaves basal. 

 Plants white-woolly, thistle-like; leaves sinuate-lobed and spinulose-toothed; corolla lavender, 2S-3S 



mm. long, its lower lip fimbriate. 2. 5". carduacea. 



Plants pubescent; leaves pinnatifid or bipinnatifid, the divisions crenate; corolla blue, 12-15 mm. 

 long, its lower lip not fimbriate. 3. S. Columbariae. 



Desert shrubs; leaves simple, spiny-toothed or entire and tipped with a spine. 



Calyx densely white-woolly, its teeth deltoid. 4. 5". funerea. 



Calyx tomentose with short branched hairs like those of the leaves, its teeth lanceolate-spinose. 



5. S. Greatai. 



Lower end of the anther-connective not prolonged below the articulation with the filament, if so, short and with- 

 out anther-cell; leaves simple, entire or crenate, never spinose. 

 Perennial herbs; corolla purplish red, about 3 cm. long; anther-connective prolonged below the articulation. 



6. S. spathacea. 



Shrubby or one species mat-like with creeping woody stems; anther-connective not prolonged below the 

 articulation. 

 Mat-like plants with creeping woody stems and short erect scape-like herbaceous flowering stems; 



leaves oblanceolate, crenate. 7. S. sonotnensis. 



Shrubs, some species low but never creeping and mat-like. 



Leaves entire, obovate to spatulate, canescent on both surfaces with minute simple hairs; bracts 

 usually colored. 

 Corolla about 15 mm. long or less, its tube pubescent within, but without a definite band of hairs. 



8. 5". Dorrii. 



Corolla about 20 mm. long, its tube with a definite band of hairs forming a transverse ring on 

 the inner surface below the middle. 9. 5". pachyphylla. 



Leaves crenate or crenulate. 



Stamens lying close under the upper lip of the corolla and little or not at all exceeding it, or 



wholly included within the corolla-tube. 10. S. mellifera. 



Stamens not lying close under the upper lip, and much exceeding it, often divaricate or declinate. 

 Pubescence of simple hairs; calyx-teeth of the lower lip evident. 

 Leaves bullate-rugose and green on the upper surface. 



Bracts pale green or whitish, membranous; lower lip of corolla longer than the 

 upper; leaves strongly reticulate and hispidulous beneath. 

 Middle lobe of the lower lip of corolla erose. 11. S. eremostachya. 



Middle lobe of the lower lip of corolla not erose. 12. S. tnohavensis. 



Bracts green, tinged with purple; lower lip of corolla shorter than the upper; leaves 

 densely tomentose beneath. 13. 5. Clevelandii. 



Leaves similarly whitish-canescent on both surfaces with minute appressed hairs. 



Flowers in capitate verticils forming a simple interrupted spike; bracts and calyx- 

 teeth prominently bristle-tipped. 14. S. Vaseyi. 

 Flowers in small branching clusters forming thyrsoid panicle; bracts and calyx not 

 bristle-tipped. 15. 5. apiana. 

 Pubescence densely canescent, composed of short much-branched hairs; calyx-teeth and 

 -lips completely united, the orifice therefore entire and very oblique. 



16. S. leucophylla. 



1. Salvia Aethiopsis L. African Sage. Fig. 4403. 



Salvia Aethiopsis L. Sp. PI. 27. 1753. 



Annual with stout branched stems, 5-10 dm. high, herbage floccose-tomentose. Lower leaves 

 ample, 1-3 dm. long, short-petioled, ovate, incised and dentate, the upper leaves greatly reduced ; 

 inflorescence ample, much-branched ; bracts orbicular, clasping, pungently tipped at apex, dotted 

 with yellow glands ; flowers 1-3 in the axils of each bract, short-pedicelled ; calyx densely woolly- 

 tomentose; corolla pale yellow, 12-18 mm. long; upper lip strongly arched, as long as the tube. 



This species, a native of northern Africa, is established in a number of places in Oregon, but most abun- 

 dantly in southern Lake County, Oregon; also in Lassen and Plumas Counties, California. June-Aug.
