 tomentose or glabrate, shrubby, 1 m. high or more, branching and

 crenate, green and rugose above, cinereous-tomentose beneath; 

 flowers in interrupted spicate heads or whorls; the floral leaves much 

 reduced, these and the ovate or oblong bracts as well as the calyx- 

 teeth of the bilabiate calyx cuspidate-acuminate or spinulose- 

 aristulate; corolla white or lilac-tinged, about 1 cm. long, the tube 

 longer than the limb; style, and especially the stamens, little exserted; 

 subulate appendages of the connective often manifest. 



Common on the low hills throughout our range. April-June. 



4. R. polystachya (Benth.) Greene. (White Sage.) Shrubby 

 below, 1 m. high or more, minutely tomentose-canescent, the

 .truncate or 3-toothed, at length concave or galeate, longer than

 lower lip much enlarged, the middle lobe rounded, emarginate at 

 apex, unguiculate, the upper lip short; tube very short; style and 

 divergent stamens long-exserted ; filiform connective continuous 

 with the filament, its lower end usually indicated by a minute tooth. 



Very common on the dry plains toward the foothills and ascend- 

 ing these to about 3000 feet. April-July. 



7. SPHACELE Benth. 



Shrubby or suffrutescent aromatic plants with the 

 floral leaves gradually reduced with rather large flowers 

 solitary in their axils, forming a leafy raceme. Calyx

1. S. fragrans Greene. Shrubby at base, 6-9 dm. high, copi- 

 ously villous, the branches leafy; leaves ovate or oblong, obtuse at 

 apex, truncate or hastate-subcordate at base, petioled, crenate, 

 obtusely serrate or entire, rugose-veiny, 2.5-5 cm. long; the upper-

 the chaparral belt, on shaded slopes. May-June.
