Spiraea

I'm interested as to which features indicate which spirea this is. I'm trying to learn to distinguish between them.
I'd expect S. salicifolia to have the entire leaf margin toothed. As this looks to only be toothed toward the tip it would appear more like S. douglasii. But is there more info in the flower spike that I'm missing?
Thanks

Spiraea salicifolia not British?

I have had a research interest in Spiraea for 20 (30?) years or more, and in that time I have seen ONE specimen of S. salicifolia, and that was a herbarium specimen more than 200 years old!

Evidently S. salicifolia was brought into cultivation around that time and earlier, and there are records of escapes, but subsequently it was replaced by N. American species and vigorous hybrids with them.

See my account in the BSBI Plant Crib for a key.
