base of these and the calyx hirsute : lobes of the latter unequal, all much longer than the 

 tube, the longer fully equalling the violet or bluish corolla ; sterile filaments small, with 

 small capitellate rudiment of antliers: style bearded above with very few coarse hairs. —

 cells slender-aristate. — Dicerandra /mean's, Benth. Lab. I.e. D. linearifolia,'Renth. in DC.

A. ilicifolia, Gray, 1. c. Low and nearly glabrous annual, slightlj' aromatic (rather 

 heavy-scented), branching from tlie base, leafy to the top : leaves coriaceous, rotimd or 

 broadly cuneate, coarsely crenate-dentate (half inch or more long, the blunt teeth of the 

 upper ones mostly mucronate or cuspidate), contracted at base into a slender petiole: 

 axils nearly all verticillastrate-floriferous : bracts a pair in each axil, almost as large as the 

 leaves, but sessile, equally coriaceous and more rigid, orbicular or dilated-subcordate, pin- 

 nately few-veined and with fine reticulated veinlets, the callous margin armed with a few 

 distant and long slender prickles, each pair subtending Z to 5 sessile flowers : corolla white 

 and rose-color, half inch long. — Southern borders of California, San Diego Co., IT'm. Rich,

27. SPHACELE, Benth. (Jqd/.o,' is the Greek name of Sage, which 

 these plants resemble in foliage.) — Shrubby or sufFrutescent plants (chiefly S. 

 American) ; with the floral leaves gradually reduced in size, and the flowers single 

 in their axils, above forming a leafy raceme. 



S. calycina, Benth. Shrubby at base, 2 to 5 feet high, tomentulose-villous or glabrate : 

 branches leafy: leaves (2 to 4 inches long) ovate or oblong, obtuse, from crenate or 

 obtusely serrate to entire, obtuse or rarely subcordate at base, rugose-veiny, more or less 

 petioled ; uppermost and bracts of the short raceme sessile : lobes of the very loose caly.x 

 triangular-lanceolate, rather shorter than the purplish or lead-colored (in(:h long) corolla : 

 anthers short. — Lab. 563, & DC. Prodr. xii. 25-5: Torr. Bot. Mex. Bound. 131, t.37 ; Gray,

 ably of shady places. — Santa Barbara Co., and southward. 



Var. "Wallacei. Copiously villous : lower cauline leaves with truncate or hastate- 

 subcordate base : calyx-lobes attenuate-lanceolate from a narrower base, over half inch
