Hi, Stephen!
I'm posting the link here so that people can more readily look at the pictures. It certainly looks like a china, maybe a tea, to me, but it's hard to identify it much further. Definitely, we need to see it in bloom.

Unlikely that it would be Fortune's Double Yellow and have flower buds now, but in Sacramento, other once-blooming roses can have a bit of repeat bloom in the fall when they've been cut back or are recovering from drought. On the California coast, a few once-bloomers repeat routinely.

If this gentleman lives near Marin County, and is interested in found roses, he needs to meet us folks in the Sacramento cemetery, don't you think?

Here is a link that might be useful: HRF Mystery Rose - Tennessee Valley

Aren't those buds beautiful?

I had to use Google to figure out where this is located -- but it is SOOOO coastal that, yes, the Asian once-bloomers would probably repeat there.
Neat Neat Neat.

Jeri, the buds remind me of Bengal Fire. Without the blossom, I don't want to jump to any conclusions.

Nor do I -- And the bud form does remind me of Bengal Fire, but I went out to refresh my memory, and the buds on my young Bengal Fire are green, and as smooth as a baby's bottom.

I don't have any of that ample glandular material that I see in Geoffrey's photos. O'course, my plant is young -- but that would be a big change.

And would'ya get a load of those stipules? Boy, I'd love to see THOSE close up!

After lunch, I'll go down and check "Single Red China" and "Emmie Gray." But I'm sure waiting for blooms. I feel like the woman in that old Mervyn's commercial, standing at the door chanting: "Open Open Open Open . . . " ;-)

these are all very interesting responses, however, it doesn't help our friend with the question if you don't add some comments to our thread......
