I would 'risk' putting it in the Cordyalis micrantha entry. If you get more photos next year and find something which suggests it isn't, then you can move the entry. Given the options and descriptions, this looks correct.
If you think about what a spur is in horse gear, such as a thing that sticks out the back, it's the same!

In this case it's not so obvious as you see in flowers like Aquilegia.
