This is one of the species of southern New Mexico and northern Mexico 
which has been passing as Cedronella mexicana, a much larger plant with 
larger flowers from some hundreds of miles farther south. It is nearest to 
Brittonastrum barberi and B. ionocalyr Robinson, both of which have larger 
corollas, the former a longer calyx and the latter a shorter one, and both much 
broader and relatively shorter calyx teeth. The species is named for Dr. E. A. 
Mearns, whose extensive collections along the Mexican boundary have added 
records of many little known species to the flora of New Mexico.

Agastache verticillata Wooton & Standley, sp. nov. 
Perennial herb, 40 to 80 cm. high, branched, puberulent throughout, green, the 
younger stems sulcate-quadrangular, slightly scabrous; leaves ovate-lanceolate, 
the blades 2 to 4 cm, long, on petioles 10 to 15 mm. long, rather thin, slightly 
paler beneath, the margins distantly and coarsely crenate-dentate, broadly 
cuneate or truncate at the base, the apex acute and somewhat attenuate in the 
upper leaves; flowers small for the genus, in an interrupted, verticillate spike 
10 to 12 cm. Jong, the verticels crowded, the internodes slightly longer than the 
fruiting calyces; peduncles and pedicels very short, 1 to 2 mm., the linear 
bracts but little longer; calyx tubular. 5 to 6 mm. long, the subulate lobes about 
one-fourth as long, unequal, two of them shorter than the others, the tube green 
below, the lobes purple; corolla slender, 10 to 12 mm. long, pale, slightly, if at

This species is nearest A. wrightii, but is easily Separated. The flowers are 
about twice as large, the calyx lobes are purple instead of white, and the leaves 
are larger and have fewer teeth. The dried calyces of the different species of 
the genus have different odors when pulverized. This species gives a pro- 
.houned odor of camphor.

Hedeoma pulcherrima. Wooton & Standley, sp. nov. 
Perennial herb, much branched, from a woody root, the stems slender, dif- 
fusely ascending. finely and sparingly puberulent throughout, about 30 em. high; 
leaves opposite, elliptic-oblong, 2 cm. long or less, the largest 7 mm. wide, taper- 
ing below into a short petiole, rather thin, green, obtuse, entire; flowers large 
for the genus, in 1 to 5-flowered cymose clusters in the axils of the leaves, the 
upper internodes and leaves somewhat reduced; floral bracts linear-lanceolate,
