    I don't know if this is something everyone but me knows, but I don't remember it. I first noticed the maple-shaped leaves, but the fruits are so wrong and the leaves are alternate, so that was just a distraction. I next noticed the hippie room divider arrangement of the small fruits, less than 1 cm.

    Thank you, Acerholic. I don't know. Nadia posted fruits from Viburnum acerifolium in 2012, not having the same curtain effect, and I don't know from where in the garden. My database list does not show this name (nor does it show V. densiflorum, an alternate name I have found), and Garden Explorer shows only one, in the Carolinian Garden. This plant is in the Asian Garden, on Lower Asian Way at the entrance to the Wilson Glade.

    I typed this last night, apparently I didn't post it or it didn't load:

    Might this be planted? Because there is a similarity to Ribes bracteosum, but it appears to be a different species.

    The critical information you have added today that it is in fact in the Lam Garden supports my earlier suspicion that it is an Asian Ribes related to or otherwise resembling R. bracteosum.

    Funny - I remember typing the location last night! [Edited - oh, that was this morning]

    Thank you. There is a Ribes longeracemosum that seems to be in the right place on Garden Explorer, called R. sanguineum on my database listing.

    I see that Ribes is the only genus in the family Grossulariaceae.

    I see Flora of China recognizes 4 vars. I'll be expecting Wendy to report back next year on which of these the UBC plant she photographed is, after she has a chance to study the flowers.

    Key characteristics don't require flowers, it should be identifiable to variety right now.

    Hmm, ok.
    1. Leaf blade is not pubescent, rules out Ribes longeracemosum var. davidii

    2. Leaf blade, calyx and fruit are not pubescent, rules out Ribes longeracemosum var. pilosum

    Leaf blade is not sparsely to densely pubescent abaxially, rules out Ribes longeracemosum var. davidii; there is a clear photo on Garden Explorer.

    3. I didn't measure the racemes and pedicels. Branchlets and abaxial leaf blade veins are not shortly glandular hairy (1st and 3rd photos above) should rule out Ribes longeracemosum var. gracillimum
    From the Garden Explorer photos, they look more like "Racemes 15-25(-30) cm, pedicels 4-10 mm; branchlets and abaxial leaf blade veins usually not shortly glandular hairy", which would be Ribes longeracemosum var. longeracemosum.
    In that fruit photo, there are a lot of short hairs, but I guess those are on the racemes, not the branchlets.
