Wall Bedstraw - 1st for Yorkshire

Today threw a complete curve ball, where I was expecting one thing but found something completely different. Work took me to Kirkshaw Lane, Ferrybridge (VC63) to look at a pond (no water and lost to swamp) but my eye was draw to a little bedstraw growing on a vegetated track nearby. My mind quickly ran through the usual options and discounted them all, leaving only one unexpected option to which it ran down quite nicely in the keys - Wall Bedstraw (Galium parisiense).

This is an uncommon species nationally, particularly this far north, and the BSBI database does not appear to hold any other records for Yorkshire.
