broadly cordate coarsely toothed leaves, which are 1| 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.

 with the leaves entire or crenate, as well as more or less broad. S. Drummondii passes by a 



gradual transition to S. resinosa. 



SALAZAKIA, Nov. Gen. 



Calyx subglobosus, inappendiculatus, breviter bilabiatus, post antliesin valde auctus, vesicu-

 longe exsertus, recurvato-adscendens, superne in fauce dilatatus; limbo bilabiato, labio superiore 

 concave apice integro, inferiore patenti-convexo apice emarginato, lobis lateralibus brevibus 

 cum labio superiore coalitis. Stamina vix exserta: antherae ciliatae, staminum inferiorum uni- 

 loculares, superiorum biloculares cordatae. Stylus apice subulatus, indivisus. Nucula3 depresso- 

 globos^ tuberculos£e. Cotyledones radicul^e brevi incumbentes. — Frutex ramosissimus ; foliis

S. Mexica:n^a. (Tab, XXXIX.) Eavines, Chihuahua, below Presidio del Norte, near the 

 Eio Grande; Parry. This remarkable plant was first discovered by CoL Fremont, in 1844, on 

 the Rio de los Angelos, a branch of the Eio 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. The leaves are about half an incb long, petiolate, ovate or oblong-lanceolate, acute at 

 the base, slightly pubescent, 3-nerved; petiole 2-3 lines long. Eaceraes 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 eg^ual lips, at leno-th 

 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 concave and incurved; lower lip 

 dilated, the sides somewhat reflexed, much shorter than the upper lip, to which they are
