 Throat of the calyx rather sparsely but not inconspicuously bearded ! 



4. CALOSPHACE, Benth. Throat of calyx naked, and of corolla not pilose- 

 annulate : anterior portion of the connective deflexed, linear or gradually some- 

 \vhat dilated downward, closely approximate or connate, and destitute of an 

 anther-cell : all American species, with upper lip of corolla erect and concave. 



* Corolla crimson, its tube villous-amwlate towards the base inside ; upper lip conspicuously 

 larger and longer than the lower: anterior fork of connectives free and spatulate-dilated down- 

 wards, obscurely one-toothed at base, longer than the filament. 



S. pentstemonoid.es, Kunth. Perennial, nearly glabrous, or below sparsely hirsute : 

 steins 2 to 5 feet high, leafy to the summit : leaves thickish, oblong-lanceolate, acute, 

 niucronate, entire or obscurely denticulate and with ciliolate-scabrous margins, the lower 

 (3 to 5 inches long) on long margined petioles; upper gradually much smaller and sessile; 

 the floral and the similar persistent bracts and bractlets of the elongated racemiform or 

 narrowly thyrsoidal inflorescence ovate-lanceolate or narrower, cuspidate: cymules subses- 

 sile, 3-5-flowcrcd : calyx equalled by the pedicels, campanulate, strongly bilabiate (half 

 inch long), glandular-puberulent ; upper lip broad, truncate, with 3 short and broad cuspi- 

 date-mucronate teeth; lower 2-parted, its teeth lanceolate and cuspidate: corolla inch and 

 a half long, slightly pubescent ; its large and nearly straight upper lip half the length of 

 the gradually enlarged cxserted tube ; middle lobe of the small lower lip concave and entire : 

 style glabrous. Ind. Sein. Berol. 1848, 13. W. Texas, on the Cibolo and Pierdenales and 

 towards the Rio Grande, Lindhf inter, Wright. 



* * Lower and sterile forks of the connectives mostly united with each other longitudinally, linear, 

 oblong, or semihastate: corolla naked within throughout, 



JT- Red or scarlet, with tube exserted; the spreading lower lip longer than the erect upper one, its 

 broad middle lobe 2-cleft : upper lip of ttibular-campanulate calyx and teeth of the 2-parted lower 

 lip ovate, mucronate-acute: inflorescence naked-racemose; the small floral leaves or bracts more 

 or less deciduous or caducous. 



S. Greggii, Gray. Shrubby, 1 to 3 feet high, glabrous or obscurely farinaceous-puberu- 

 lent : branches slender, leafy : leaves coriaceous (3 to 9 lines long), 1-ribbed, almost vein- 

 less, oblong, very obtuse, entire, narrowed at base into a short petiole: flowers rather few 

 in the raceme: calyx slightly pubescent or glandular (barely half inch long), with at 

 length spreading lips fully hal'f the length of the tube : corolla (inch long, " red " or " pur- 

 plish-red ") glabrous; its tube enlarging and strongly ventricose-gibbous ; throat abruptly 

 contracted under the lower lip, which nearly equals the slightly glandular-puberulent upper 

 one : lower fork of connective oblong-linear : style hairy along the upper side. Proc. Am.

S. COCCinea, L. Perennial or annual, canescently pubescent or glabrate, or hirsute tow- 

 ards the base with long spreading hairs : leaves membranaceons, veiny, cordate or ovate, 

 mostly acute, crenate, slender-petioled, mostly soft-tomentulose beneath : raceme virgate ; 

 the clusters few-several-flowered and rather distant : lips of the calyx hardly half the 

 length of its tube: corolla (inch or less long, pubescent or puberulent outside) deep scar- 

 let-red, twice or thrice the length of the calyx ; its narrow tube moderately enlarging 

 above ; lower lip twice the length of the upper, from which the stamens protrude : lower 

 forks of the connective long and narrowly linear: style glabrous. --Mant. 88; Mnrr.

= Flowers from near an inch to over half inch and calyx fully quarter inch long: inflorescence 

 virgate-racemose or spiciform, sometimes paniculate: small floral leaves or bracts mostly decidu- 

 ous: corolla with prominently exserted tube, erect and very concave or galeate and pubescent 

 upper lip; the lower longer and much larger: style bearded above: perennials, 1 to 5 feet high.
