Diversity was measured by the #families, #genera, #species in the collection. The UC Garden tops all other N. American gardens in the families and genera and has the 3rd largest number of species. However, it appears our collection is unequaled based on the number of acquisitions with provenance (of wild origin)k. In fact, we would easily have greater diversity if we didn't adhere to our policy of wild collected material with provenance. In thinking of this, it is a way that PBS may help us build the collection. We could discuss this issue. I'm off to pollinate our new titan arum. Paul Paul Licht, Director Univ.
