I'm now sure that this is the species caffra
Flowers appear in a whirl at the end of the twig before leaves.
This one is by Quaglino's Tru-Value on High Street.
There is another on the Cal Poly campus in front of one of the brick dorms.
Now it is 2006.0501 and I am no longer so sure of this identification. I shall follow up on it further and try to get an expert opinion.
