Clinopodium ascendens Common Calamint C DD N
Another of those plants which has been affected by the messings of the taxonomists, Clinopodium ascendens used to be called Calamintha ascendens. I'm sure the change was absolutely essential. Locally, I only see this in limestone country where it grows in grassland alongside Silene nutans, and Hypochaeris maculata.
C ascendens is common in the southern counties of England and extreme south of ireland but records quickly didmish as you go north. There is little in northern Ireland or Scotland.
