Shrub, 1 meter high or less, or sometimes herbaceous; leaves sessile or short-

 usually few-flowered; corolla red, the tube 15 to 32 mm. long. "Trompetilla"

 (Oaxaca, Reko); "hierba del indio" (Sinaloa). 



A handsome plant and, like some of the other species, often cultivated. It is 

 employed locally as a remedy for dj'sentery and hydrophobia and other affections. 



Dr. Reko states that the ancient Mexicans were accustomed to begin the 

 treatment of a disease by bleeding, which was induced by provoking hemorrhage 

 from the nose with powder of "cebadilla" {Stenanthium frigidum); and to 

 restrain excessive hemorrhage they used the powdered roots of the tlacoxochitl. 



The plant is described and figured by Herndndez.' It is probably also the 

 one mentioned by Sahagun under the name tlacoxochitl. The latter author 

 says: "The flavor of the roots is both bitter and sweetish. They are good for 

 heat and exhaustion of the heart. Ground with about 15 grains of maize and 

 as much cacao, and mixed with water, they should be taken several times on an 

 empty stomach or after meals."
