Geog. note. — Lappula floribunda is found throughout the Rocky Mountains in the United 

 States, a representation of the species which is marked by large corollas. This large-flowered 

 condition is found in California only in the Warner Mountains of eastern Modoc Co. (Lake City 

 Canon, R. if. Atistin 4- C. C. Bruce 2268). The prevailing form of the species in California is 

 consistently small-flowered but does not differ in any other particular from the formal type of 

 the species in Colorado. It is here listed as follows:
