Preceding works

''The Jepson Manual'' also follows Philip A. Munz and David D. Keck in their ''A California Flora and Supplement'' of 1958 and 1968. Like other florae, ''The Jepson Manual'' builds upon these prior publications. Except for the number of line drawings, it has more in common with Munz's 1968 book than with Jepson's 1923 book.
