CEDRONELLA CANA, Hook. Bot. Mag. t. 4618. Near the Copper Mines; Bigelow, Wright. 
Burro mountains; Bigelow. Perhaps not distinct from C. Mexicana. No. 1532, Wright, has 
broadly cordate coarsely toothed leaves, which are 1j inch long and more than an inch wide. 
In the specimens from the Copper Mines (No. 1533, Wright) the leaves are ovate or oblong, 
8-10 lines long and rather sparingly toothed or almost entire. Our specimens from the Burro 
mountains have lanceolate leaves, of which only a few of the lowest are slightly toothed near , 
the base. |

foliis ovato-oblongis basi acutiusculis. (No. 1534, Wright.) Differs from C. cana in the more 
dense and spike-like inflorescence, and in corolla being only a little longer than the calyx.

gradual transition to S. resinosa, Thr Y Ap 8 4

8. MEXICANA. (Tap. XXXIX.) Ravines, Chihuahua, below Presidio del Norte, near the 
Rio Grande; Parry. This remarkable plant was first discovered by Col. Frémont, in 1844, on 
the Rio de los Angelos, a branch of the Rio Virgen, western New Mexico ; but the specimens 
were too much injured for description. It is a shrub 2 or 3 feet high, with numerous slender 
spreading or reclinate branches, which are terete and hoary, with a minute appressed pub- 
escence. Тһе leaves are about half an inch long, petiolate, ovate or oblong-lanceolate, acute at 
the base, slightly pubescent, 3-nerved; petiole 2-3 lines long. Васетев 2—6-flowered, ter- 
minating the branches. Flowers on short pedicels, as large as those of Scutellaria galericulata, 
which they much resemble. Calyx, at first, with entire, very obtuse and equal lips, at length 
very much enlarged (nearly three-fourths of an inch in diameter) and bladder-like, with a con- 
tracted orifice. Corolla nearly an inch long; the upper lip concaye and incurved; lower lip 
dilated, the sides somewhat reflexed, much shorter than the upper lip, to which they are
