Alan,
I know it sounds difficult to do but I can tell it’s not Comice by the dormant wood. The buds are extremely close together and very small. I could be wrong but I have seen close buds with Harbins and a small tree just makes me think it’s gold spice. Gold spice is said to be a harbin cross.
Mark,
Do you have pictures of a dormant gold spice branch? Is the wood a tannish color? I know it sounds a little weird but some pears are red wood, some are tan, and some wood is green etc. . Some wood such as warren pear as an example is green with spikes whereas Douglas is green without spikes. I can tell a lot just by the dormant wood. Worden is actually supposed to be larger than Seckel Worden Pear - #2 by scottfsmith
This is an old print of Worden I located with an internet search. That pear in the print and the pears at Corvallis are identical.
We can definitely rule out Seckel and Worden for this mystery pear but the size must be similar so I really think gold spice is right. What other pear could it be I wonder? To verify my Worden I requested both forelle and Worden wood from Corvallis and my Worden Is Worden.
