Checklist of Stanford Eucalypts: Current and Historical Plantings

Stanford has had in the past one of the most diverse collections of Eucalyptus in California and still has some mature specimens of very rare and unique trees. The following two tables list 134 taxa of Eucalyptus known to have been planted on campus. Ron Bracewell reported 94 species, subspecies, and hybrids growing on campus as of March 1980, including trees at Heliopolis, 3185 Alpine Road, his former radio astronomy research site. A number of species had been already lost in the 1972 freeze.

Ron Bracewell memorial grove and bench

In August, 2007 Dr. Matt Ritter provided Herb Fong with 26 trees representing 8 species for planting on campus. All should thrive in local climate conditions. All were raised from seed. Detailed below are the number of individuals, species name, source or provenance if known, and the approximate seed-planting date. For those that were collected from horticultural trees in California, progeny were checked to make sure they lacked any hybrid characteristics. Hybridization of Eucalyptus in cultivation is rare in general. February, 2008 the young trees were planted in the Ron Bracewell Grove south of the vernal pond on Lasuen. Jean Lane honored Ron with the donation of a bench. The trees have been plotted on Grounds Sevices young specimen tree inventory map and are being monitored monthly.
