Another Swindon "speciality"
This is Narrow-leaved Bird's-foot Trefoil (Lotus glaber, formerly known as L. tenuis) and it grows in great quantities in West Swindon (here in short grassland at Shaw Forest Park, 30th June 2016).
When I moved to Swindon from Frome, about 40 miles to the SW, there were a few plants that really struck me e.g. Stone Parsley, Goat's-rue... This should have been another one, except I completely overlooked it (mistaking it for normal Bird's-foot TrefoilI, I suppose). I've only heard about it in the last couple of days, thanks to a couple of Swindon-based colleagues in the Facebook group "Wild Flowers of Britain". Time for a stroll in the park...
There really is a lot of it!
Here's a single plant growing in longer grass, which actually makes it easier to see the narrow leaflets that are the key identifying feature.
Close-up of those narrow leaflets. I think my close-up camera must have had rain on the lens!

Old illustration showing the differences between the three commoner Bird's-foot Trefoils. Lotus glaber is the one in the middle. The one on the left is normal Bird's-foot Trefoil (Lotus corniculatus). The one on the right is Large Bird's-foot Trefoil (Lotus pedunculatus, formerly L. major, L. uliginosus).
Below is my own educational presentation of Lotus glaber (left) and Lotus corniculatus (right):

And finally, here's a photo from a re-visit on 11th July, when the weather was a lot brighter!
