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 anthers : style bearded above with very few coarse hairs.

25. CERANTHERA, Ell. (AY^-, a horn, and r%>, anther: cells of 

 the anther cornute.) Peculiar to the southern Atlantic States, nearly glabrous 

 and slender erect annuals, a foot high, sweet-aromatic; with broadly or narrowly 

 linear and obtuse entire leaves ; the uppermost on the virgate branches diminished 

 to similar bracts of the thyrsoid-racemose inflorescence. Flowers autumnal, 

 handsome: corolla pink-purple and spotted, the calyx commonly purplish.

C. linearifolia, Ell. 1. c. Inflorescence loose : cymes short-peduncled, few-flowered : calyx- 

 teeth obscurely ciliolate, hardly equalling the tube of the (about half inch) corolla: anther- 

 cells slender-aristate. Diceratulm linearis, Benth. Lab. I.e. L). linearifolia, Benth. in DC.

C. densiflora. Inflorescence dense ; the pedicels shorter and peduncle hardly any : 

 calyx-teeth appressed-eiliate, equalling the tube of the corolla : anther-cells conical-cor- 

 nute : leaves mostly shorter and broader. Dicerandra densiflora, Benth. in DC. Prodr. 1. c.

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

 heavy-scented), branching from the base, leafy to the top : leaves coriaceous, rotund 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- 

 na tely few-veined and with fine reticulated veinlets, the callous margin armed with a feu- 

 distant and long slender prickles, each pair subtending 3 to 5 sessile flowers : corolla white 

 and rose-color, half inch long. Southern borders of California, San Diego Co., Win. Rich, 

 Cleveland. Allied to Glcc/ton of Brazil, which is also referred to this tribe, rather than to 

 the StackydecB. 



27. SPHACELE, Benth. (Zydxo^ 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 crcnatc 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 calyx 

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

 anthers short. Lab. 5GS, & DC. Prodr. xii. 255; Torr. Bot. Mex. Bound. 131, t.37; Gray, 

 Bot. Calif, i. 598. Hillsides, common throughout the western part of California, especially 

 from San Francisco southward. 



Var. glabella, Gray, 1. c. A minutely tomentulose and soon glabrate form, prob- 

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



Var. Wallace!. Copiously villous : lower cauline leaves with truncate or hastate- 

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

 long. Probably near Los Angeles, Wallace.
