    This tree is in the Asian Garden, on Lower Asian Way and Farrer. Nadia thinks it's in the Styracaceae family. The fruits are maybe 4cm long, shiny reddish-brown, and the popular arrangement seemed to be for them to hang in pairs.

    It has a tag - see it there next to the trunk? That's with a 12x zoom, and I can just make out that the name ends in odendron or odendrom, the family begins with S, and it's from China.

    Probably Rehderodendron. The fruits are floats that disperse the seeds via water.

    Yes, Ron is correct. It's a Rehderodendron. It has not been identified to species.

    Great, thanks Ron and Eric.

    Maybe when we talked about Rehderodendron in the May 31 posting, it was the macrocarpum. I looked at the POTD posting yesterday, as the name was the only one I could think of, but seeing the flower photo, I thought "no, that's totally different" and I didn't even click through to see the fruit.

    Nadia was of course right that it's Styracaceae.

    We found another Rehderodendron last week, and were even able to find it again yesterday - R. gongshanense, up a path above Upper Asian Way north of the Meyer Glade. We saw three of these, two different accessions from 2000.

    Looks pretty similar to the first one.

    Here are flowers on the Rehderodendron gongshanense. It's in the group of trees pictured just previously but the other accession. They're just starting to open.
