FLOWERING PLANTS AND FERNS OF ARIZONA Ti i 



places, summer. Widely distributed in the cooler parts of North 

 America; Eurasia. 



The Rocky Mountain (and Arizona) form of this widespread com- 

 plex is subsp. pilosa (Nutt.) Epling. The flowers are lavender pink. 



16. SALVIA.® Sage 



Shrubs or herbs of varied habit; flowers in interrupted spikes or 

 terminal heads; calyx 2-lipped, usually laterally compressed, the 

 upper lip commonly entire, less often 3-mucronate or 3-toothed, the 

 lower lip usually 2-toothed; corolla blue, red, or white, tubular, 

 strongly 2-lipped, the upper lip either plane and notched, or galeate 

 and entire; stamens 2, exserted from the corolla-tube beyond the 

 limb, or contained within the galea, the connective strongly developed, 

 often more prominent than the filament, bearing a single terminal 

 anther sac (rarely one at each end), either straight and projected 

 back into the corolla tube, or geniculate; style usually exserted from 

 the galea or beyond the upper lip ; nutlets smooth. 



Key to the species 



1. Upper lip of the corolla essentially plane or laterally reflexed and usually 

 notched, not at all galeate: stamens clearly exserted beyond the tube and 

 limb of the corolla (2). 

 2. Plant annual, with dissected leaves; lower arm of the connective bearing a 



fertile anther sac; corolla light blue 1, S. coloibariae. 



2. Plants shrubby (3). 



3. Leaves rugose, deltoid or oblong-elliptic, crenulate, green, thinly his- 



pidulous 4. S. MOHAVENSIS. 



3. Leaves smooth, obovate, entire, canescent (4). 



4. Calyx 5 to 7 mm. long; corolla tube 5 to 10 mm. long, pubescent within 



above the middle 2. S. carnosa. 



4. Calyx 8 to 13 mm. long; corolla tube 15 to 22 mm. long, strongly pilose- 

 annulate below the middle 3. S. pachyphylla. 



1. Upper lip of the corolla clearly galeate, including the stamens, or these not 

 much exserted (5). 

 5. Leaves 10 to 25 cm. long; flowers subtended by persistent sheathing bracts; 



a coarse woolly herb 14. S. aethiopis. 



5. Leaves rarely as much as 8 cm. long; bracts deciduous or, if persistent, not 

 sheathing the flowers (6). 

 6. Perennial herbs; leaves usually pinnate, at least below: stamen connectives 

 bearing fertile thecae at both ends: flowers red 7 . 

 7. Leaves 3-foliolate, or simple by suppression of the lateral pair of smaller 

 leaflets, the terminal leaflet essentially rotund or broadly and ob- 

 tusely deltoid, coarsely sinuate-dentate - 5. S. davidsoxii. 



7. Leaves 3- to 5-foliolate, rarely simple by suppression of the lateral 



leaflets, the terminal leaflet deeply and irregularly toothed or lobed. 



6. S. HEXKYI. 

 6. Perennial or annual herbs, or shrubs; leaves simple throughout; lower 

 theca of each stamen wholly abortive; flowers blue or (in S. lemmont) 

 purple (8). 



8. Stamen connective essentially straight, directed downward into the 



tube and across it, usuallv bearing a small triangular tooth near the 

 middle (9). 

 9. Verticils usually several-flowered: leaves deltoid-ovate, 5 to 10 cm. 

 long; corolla violet, the tube 6.5 to 7 mm. long. 12. S. AMISSA. 

 9. Verticils mostly of 2 opposite flowers (10). 



10. Plant annual: corolla blue 11. S. reflexa. 



10. Plant perennial, suffrutescent; corolla lavender pink. 



13. S. LEMMONI.
