(1979) pointed out that O. fontana is the oldest correct 
name for this taxon, Eiten’s (1963) assessment of 
infraspecific variation in the species is more 
reasonable; thus O. fontana var. bushii (Small) Hara, 
recognized by Lourteig (1979) and with type from 
Missouri, is here relegated to synonymy), p.
