puberulent: flowers in anthesis 12 to 18 mm. long: calyx bilabiate, 6 to 

 7 mm. long, 13-nerved, glabrous or with a few scattered hairs on the 

 outer surface, glandular-punctate, pubescent in the throat; anterior lip 

 of 2 rather slender long-ciliated teeth ; posterior lip of 8 short obtuse or 

 blunt teeth : corolla 12 mm. long, pale purple, somewhat pubescent in 

 the throat ; anterior lip spreading, 3-lobed ; posterior lip suberect, emar- 

 ginate : stamens 4, unequal ; the anterior pair much longer than the pos- 

 terior, and with somewhat larger anthers : nutlets ovoid, about 1 mm. 

 long, minutely scrobiculate. — Mexico. State of Hidalgo: shaded 

 banks, barranca below Trinidad Irou Works, altitude 1685 m., 5 May, 

 1904, C. G. Pringle, no. 8895 (hb. Gr.). Mr. Pringle's plant here cited 

 was distributed under the name " Calamintha." 



Salvia (Heterosphace) Davidsonii, n. sp. An herbaceous peren- 

 nial : stems slender, ascending or erect, finely pubescent: leaves petiolate, 

 the lower or basal ones lyrately pinnatifid, the upper rhombic-ovate, 1 to 

 3 cm. long, 0.5 to 2.5 cm. broad, sinuately lobed to subentire, pale green 

 in color at least in the dried state, sparingly pubescent on both surfaces, 

 resiniferous-dotted, commonly 3-nerved from a symmetrical or not infre- 

 quently unequal base ; petioles narrowly winged, 1 to 6 cm. long : flowers 

 solitary in the axils of the upper leaves or disposed in terminal few- 

 flowered verticillate racemes : pedicels erect or slightly recurved, 5 mm. 

 or less in length : calyx externally short-hirsute-pubescent especially 

 on the rather conspicuous veins, dotted with yellowish glands, sparingly 

 ciliate-hirsute in the throat : corolla about 1 cm. long, red : nutlets smooth. 

 — Arizona: Chiricahui Mts., September, 1881, Lemmon, no. 3077 

 (hb. Gr.) ; southern Arizona, Lemmon, no. 492 (hb. Gr.) ; Metcalf, 

 October, 1900, Dr. A. Davidson, no. 615 (hb. Gr.). 



S. Davidsonii is most nearly related to S. Henryi, Gray, to which 

 species one of the Lemmon plants above cited was referred by the late 

 Dr. Sereno Watson. The several specimens now at hand, however, 

 representing S. Davidsonii , are so uniform in habit, foliar and floral 

 characters, and so distinct in leaf-outline, size of the corolla, etc., from 

 S. Henryi and other species of the group, that the writer has no hesita- 

 tion in regarding them as representing a separate and well defined 

 species. 



Bassovia stellata, n. sp. Shrub, 2 m. or more in height ; stem 

 covered with a reddish brown cortex ; branches, as well as the leaves, 

 pedicels and calyx, tawny stellate-pubescent, somewhat glabrate : leaves 

 usually in pairs and of unequal size, ovate to ovate-lanceolate, 2 to 8 cm. 

 long, 1 to 3 cm. broad, often acuminate, obtuse or acute, dark green
