WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 167 
1897, Wooton 437; San Augustine Ranch, alt. 1,740 meters, August 16, 1895 
Wooton; Soledad Canyon, September 24, 1905, Wooton. 
This is without doubt the plant which Hooker described and figured as 
Cedronella cana. The locality cited in Wright’s field notes indicates that the 
type was collected in the low mountains, probably the Huecos, about 30 miles 
east of El Paso, possibly near the Hueco Tanks, which were then a watering 
place on the route leading across the plains from El Paso, the one probably fol- 
lowed by Wright’s party. The Organ Mountains, where we first found this 
plant, are the next chain to the northwest, and only a little farther away than 
El Paso. The plant collected by G. R. Vasey and referred to by Doctor Gray in 
his description of Cedronella cana lanceolata is C. cana from the Organ Moun- 
tains, in all probability. This is the only Agastache in the National Herbarium 
collected by Vasey, and this herbarium should contain specimens of all his 
collections. We have not seen the Wright specimen referred to by Gray in his 
description of lanceolata, which was probably his no. 1533, collected at Santa 
Rita. The Rusby plant from Mangas Springs that deserves the name of 
lanceolata is Cedronella rupestris, an excellent species which has been collected 
several times since in the immediate region. The Burro Mountain plant col- 
lected by Bigelow is also that species. 
Agastache greenei (Brig.) Wooton & Standley. 
Brittonastrum greenei Briq. Ann. Cons. Jard. Genéve 6: 157. 1902. 
We do not agree with Doctor Rydberg in considering this a synonym of A. 
pallidifora (Heller) Rydb. A rather extended series of the Arizona plant 
from various localities and also from western New Mexico in the Mogollon 
Mountains, shows that it has a green calyx and pale whitish flowers, while A. 
greenei has the calyx teeth and upper part of the tube decidedly pink or pur- 
plish tinged and the corolla also brighter colored. Besides these more con- 
spicuous calyx differences, the corollas in A. greenei are noticeably longer, 
more arched, and wider at the throat. These differences in color and size of 
corolla and calyx and noticeable ones in the calyx teeth seem to be the most 
important diagnostic characters in a group of closely related but distinct 
species which have until recently been considered as belonging to two or three 
very variable ones. 
Agastache mearnsii Wooton & Standley, sp. nov. 
Herbaceous, branched perennial, about 70 cm. high, with several erect stems 
from the base, finely puberulent throughout; stems distinctly quadrangular, 
suleate above, below almost terete; petioles mostly 10 to 12 mm. long; blades 
25 to 50 mm. long, about two-thirds as broad, triangular to hastate, sometimes 
ovate, mostly truncate at the base, acute to abruptly short-acuminate, coarsely 
crenate-dentate, finely and closely puberulent beneath and pale; flowers numer- 
ous, in crowded, terminal, spike-like clusters 10 cm. long and 3 to 4 cm. wide 
when in full flower; peduncles and pedicels 2 or 3 mm. long, the linear-subulate 
bracts about 5 mm. long; calyx tubular, reddish purple, 10 to 12 mm. long, the 
triangular-subulate, almost equal teeth fully 2 mm. long, erect; corolla about 
20 mm. long, reddish purple, somewhat arched, puberulent outside, the upper 
lip retuse, the lower 3-lobed; stamens 4, the longer pair exceeding the corolla; 
nutlets brown, scabrous at the apex. 
Type in the U. S. National Herbarium, no. 233421, collected in a canyon on 
the east side of the San Luis Mountains in extreme southwestern New Mexico, 
nearly on the Mexican boundary line, September 11, 18938, by Dr. HE, A. Mearns 
(no. 2251).
