Calif. Flora - Jepson or Munz?

[goldsmig at cgsvax.claremont.edu]

Might someone provide an opinion on the comparison of Willis Linn Jepson's
"The Jepson Manual:  Higher plants of California" (Berkeley: Univ. of 
California Press, 1993) and Philip A. Munz's "A California Flora"  (Date
unknown)?

Both appear to be comprehensive treatments of native California flora.
What are the differences and strong points of each?

Thanks very much in advance.
