WOOTON AND STANDLEY FLORA OF NEW MEXICO. 215 



Torrey reported ' Gomphrena tuberifera Torr. from New Mexico, but this is probably 

 incorrect, since the species ranges much farther south in Texas. 



1. Gomphrena nitida Rothr. in Wheeler, Rep. U. S. Surv. 100th Merid. 6: 233. 1879. 

 Type locality: Chiricahua Mountains, southern Arizona. 



Range: Arizona and southwestern New Mexico. 



New Mexico: Kingston; San Luis Mountains; Organ Mountains; Gila Hot Springs. 

 Dry hills, in the Lower and Upper Sonoran zones. 



A strict annual with erect opposite branches, mostly sessile leaves, and flowers 

 in a terminal head subtended by a pair of bractiform leaves. The scales are frequently 

 tinged with red, adding to the similarity to the cultivated bachelor's button. 



2. Gomphrena caespitosa Torr. IT. S. & Mex. Bound. Bot. 181. 1859. 



Type locality: "Gravelly plains near the Organ Mountains, New Mexico; also

 in the Lower and Upper Sonoran zones. 



This little plant usually first appears as a rosette of oblanceolate to obovate, white- 

 hairy leaves, with ovoid heads of small yellow flowers subtended by silvery white 

 bracts. Later the slender and decumbent stems with smaller opposite leaves appear, 

 and the plant spreads to 10 to 20 cm. in diameter. In the type locality it is rarely larger 

 than this, probably because it is eaten by stock.
