Wallaby, it was a sale at the San Francisco Arboretum, which certainly is filled with some of the premier experts in the field. The fact that they could only label it "Jasminum" made me wonder whether anyone would ever be able to identify it more specifically, but Dave's Garden is full of incredibly knowledgeable people, so I thought I'd take a shot.
The flowers on mine were a very intense color and did not fade or change color as they aged. They were tiny, the same size as the head of a conventional thumbtack, and they do have a yellow eye. The flower clusters were erect at all times and never had a tendency to droop. The buds were all one color, without any of the white that's apparent in some of the j. beesiana photos I found on Google. The leaves are small but quite thick, as thick as the leaves on some Gardenias and Dipladenias (and Jasmines, for that matter).
The plant isn't blooming right now, but here's a closup of the earlier photo without all of the extraneous scenery.
