Mackenzie and Bush — Lespedezas of Missouri. 19 



specimens greatly resemble some of the yellow-flowered species, 

 whence the specific name. But here the presence of apeta- 

 lous flowers at once furnishes a chie for its identification. 



The species is found in southwestern Missouri and adjacent 

 Indian Territory in the Ozark Mountain region, in dry rocky 

 open woods, and on high rocky mounds and prairies. 



Type locality, Newton County, Missouri ; collected by 

 B. F. Bush, Aug. 25, 1893 ; type in herb. Missouri Botani- 

 cal Garden, duplicate in herb. K. K. Mackenzie.
