becoming sessile, deltoid-ovate to oblong, cordate at base, coarsely 

 crenate, 3 to 7 cm. long: verticels 3-6-flowered, remote, only the lower 

 conspicuously leafy-bracteate : pedicels very short : calyx minutely puber- 

 uleut, ill anthesis (i mm. long, cleft half way to the base into lance-subul- 

 ate teeth: corolla apparently pale, 1.1 to 1.3 cm. long; the tube once 

 and a half as long as the calyx; the 3-lobed lower lip twice as long as 

 the entire short pubescent galea. — Oaxaca, Hacienda de Caciques, Dis- 

 trict of Cuicatlan, Aug. 4, 1895, alt. 2,150 m. {L. G. Smith, no. 612). 

 Apparently related to S. Drummondii, Benth. 



S. (Calostachys) oaxacana. Stems slender, 2.5 to 6 dm. high, 

 densely retrorse-hispid below, sparingly so or only glandular-puberulent 

 above : leaves deltoid-ovate to deltoid-lanceolate, coarsely crenate, 

 cordate or truncate at base, 1.5 to 3.5 cm. long, above somewhat strl- 

 gose-pubescent, beneath more or less pubescent, often white with 

 appressed longitudinally spreading stiffish hairs ; petioles slender, the 

 lower equalling the blades, the upper shorter : verticels 4-6-flowered, 

 rather remote, only the lowest conspicuously bracteate : pedicels about 

 equalling the calyx : calyx green, glandular-puberulent, in anthesis 

 5 ram. long, in fruit becoming as broad as long, with 5 deltoid-subulate 

 teeth : corolla scarlet, 2 to 2.5 cm. long, minutely puberulent or glabrate 

 without ; the 3-lobed lower lip slightly exceeding the entire or emargi- 

 nate galea. — Oaxaca, near Reyes, alt. 2,060 to 3,080 m., Oct. 20, 

 1894 {E. W. Nelson, no. 1795) ; Sierra de San Felipe, alt. 2,150 m., 

 Sept. 23, 1895 (C. Gonzatti, in exsicc. L. C. Smith, no. 709) ; mountains 

 of San Juan del Estado, alt. 2,300 m., Oct. 21, 1895 (Z. G. Smith, 

 no. 924) ; Cuicatlan, alt. 1,675 ra., Dec. 9, 1895 ( F. Gonzalez, no. 47). 

 Closely related to S. coccinea, Jacq., with which it has formerly been 

 confused, but from which it is distinguished by its very slender habit, 

 smaller calyx and different pubescence. 



Calamintha oaxacana. Shrub with smooth brown bark, and very 

 slender minutely puberulent or glabrate branchlets : leaves thin, elliptic- 

 ovate, 1 to 1.5 cm. long, finely and sharply serrate, acute at tip, nar- 

 rowed or rounded at base ; petioles filiform, about equalling the leaf- 

 blades : flowers solitary, axillary, on slender 2-bracteate pedicels 5 to 

 8 mm. long : calyx tubular, 13-costate, in anthesis 6 to 7 mm. long ; 

 the tube twice exceeding the lance-subulate lobes ; the upper lip with 

 3 upturned lobes, the two lobes of the lower straighter : corolla red, 

 3 to 3.25 cm. long, short-pubescent without. — Oaxaca, El Parian- 

 Etla, alt. 1,200 m., Nov. 1898 ( F. Gonzalez & G. Gonzatti, no. 901). 

 Nearest related to G. coccinea of the southern United States. Habit-
