 Sporoholus cuspidatus (Torr.) Wood, Mackenzie and Bush in 

 Manual of the Flora of Jackson County, Missouri, No. 4. 1 902 ; 

 Daniels in Flora of Columbia, Missouri, No. 81, 1907, but 

 very doubtful, as this speoies is not known to get as far east 

 in Missouri. Dr. Daniels has omitted several very common 

 species of Sporoholus from his Flora, and I suspect that 

 one of these has been mistaken for M. cuspidata.
