 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 tlie 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-annulate towards the base inside ; upper lip conspicuously 

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

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



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

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

 mucronate, 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-tlowered : calyx equalled by the pedicels, campanulate, strongly bilabiate (lialf 

 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 exserted tube ; middle lobe of the small lower lip concave and entire : 

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

 towards the Rio Grande, Lindheimer, Wright. 



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

 oblong, or semihastate: corolla naked within throughout, 



^^ 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 tubular-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 half 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. COCoinea, L. Perennial or annual, canescently pubescent or glabrate, or hirsute tow- 

 ards the base with long spreading hairs : leaves membranaceous, 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 ; Murr. 

 Comm. Gott. 1778, t. 1. — Var. pseudo-coccinea is a commonly tall form of this species, 

 with stem, petioles, and often margins of floral leaves conspicuously beset with hirsute 

 hairs. .S. psi'udo-rorcinea, Jacq. Ic. Rar. t. 209 ; Bot. Mag. t. 2864. S. ciliata, Behth. Lab.

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

 virfcalc-raceniose or spiciform, sometimes paniculate; small floral leaves or bracts mostly decidu-
