The species that I collected on the Stanford campus, for which I was able to confirm the identification are the following:
These species were all known and the location is known, I just confirmed their identification as being correct.
- E. pellita
- E. platypus
- E. intertexta
- E. dundasii
- E. resinefera
- E. kruseana
- E. pulverulenta
- E. redunca
The tree on the Euc. walk that was described as a E. botryoides hybrid appears to actually be one. It matches E. botryoides in all its characters except that it has wholly smooth bark. There are no close relatives of E. botryoides with wholly smooth bark so this may be a strange cultivar, individual, mutant, or hybrid.I’m not sure.
The resprouting tree on the Euc. walk area may be E. albens, but we’ll have to wait to make sure.This resprouting specimen should be protected until it can reproduce. The three rough barked trees that we saw over near palm drive were: E. bridgesiana (near where we parked the cars, 5-10 yards to the west of Lasuen St. between campus drive east and Arboretum Rd.) E. paniculata (near the intersection of Palm Drive and Arboretum Rd, a few yards to the east of Palm Dr.) E. creba (near the intersection of Palm Drive and Arboretum Rd, 5 yards to the west of Palm Drive, on the same side of the road as the large Torrey Pines)
There were a number of trees we looked at after leaving campus. I collected material from one at the corner of Peter Coutts Rd and Tolman.These trees are all E. mannifera.I think these were identified as E. maculosa by Bracewell.E. maculosa is a synonym of E. mannifera.
The rough bark tree we looked at in Ron Bracewell’s back yard was in fact E. agregata.
The trees that were planted together in the collection near the intersection of Raimundo and Wing Place in Palo Alto:
- E. viridis
- E. megacornuta
At this same site there was the large, smooth barked tree. I believe this is E. oleosa ssp. oleosa. It matches E. oleosa very well in its fruit and bud characteristics. The tree is larger than a typical E. oleosa (my experience with this species is minimal) and the bark on E. oleosa isn’t usually smooth throughout. However, there are no other species that match this tree as closely.
The last remaining unidentified tree was the mallee next to the Angophoras at the old nursery site. This is most like E. parvula (syn. E. parvifolia). To make a complete confirmation I would need to look at the buds.They were just coming out when I was there. It may be in full flower soon. If you could collect more material I could make a confident identification of this tree.
I also collected the following species at 3185 Alpine Road:
- E. blakelyi
- E. acaciiformis
- E. gunnii
I’ve attached some small, low resolution photos to this email and I will be sending you a CD with the full size images soon.
