Can anyone help me to identify a tree in my road? It has seeds very like horse chestnut 'conkers' in shape, size and colour, but they are produced in smooth olive-green pear-shaped fruits, not in spikey fruits like a horse chestnut. At this time of year I have no leaves available, but I think they were fairly small.
You pose a bit of a challenge without a photo...
There are a few possibilities, but let me go with my gut and suggest
- yellow buckeye, Aesculus flava
(There are other buckeyes, eg. A. octandra
You should be able to find the leaves (and leaf stalks) on the ground somewhere nearby.
Thank you for this very quick reply. I am pretty sure you are right with the A. flava identification, having looked at the photos in the links you provided. I will watch the tree carefully next season to try to confirm this from its leaves and flowers. Meanwhile I have planted some seeds!
If the yellow buckeye turns out not to fit, the next one I'd look at is one of the walnuts (probably English or black). The leaves of the buckeyes and walnuts are quite different: buckeyes are palmate (the leaflets arising from one point); walnuts are pinnate (the leaflets arranged along a leaf stem).
