Hi Otto,
Can't comment on the left-hand one other than very Rubus-like - I have Rubus chamaemorus (wild and jam) in my collection at home though so can check next week. At least it isn't Rubus arcticus - rather smooth as I've just discovered by collecting some from a splendid patch we have growing at Boreland. Middle one looks like a Betula fruit that's lost the wings and right-hand one - Ranunulus/aceae?
Do you have access to Katz, Katz and Kipiani (1965) - Atlas and keys of fruits and seeds occurring in the Quaternary deposits of the USSR? That might help.
All the best
Jacqui
Dear colleagues,
Currently, I am involved in a project for which the RCE reference collection is highly inadequate: plant remains from the Allerod/Younger Dryas transition of
a site named Den Treek. Attached are three photos, one I think may well be Rubus chamaemorus (without reticulate pattern), another is clearly Rubus, but maybe not fruticosus s.l., and the third is likely a Rosaceae as well of which I don’t even now the genus.
There is mm-paper on the background. The vegetation in those days was dominated by Pinus and Betula, the latter most likely B. nana as well as tree birches. I reduced the size of the photos to what I think is adequate. If you need larger ones for a good identification,
I can send this off-list on request.
All suggestions are highly welcomed!
