vetches and tares

I've spent a little time to identify some of the vetches and tares in the area.

The tare growing around the allotment site appears to be (from counting leaflets in a leaf, and flowers in an inflorescence) hairy tare (Vicia hirsuta), though the usual key character given in the hairy fruit, which is not yet available for examination.

The reddish-flowered vetch, with flowers solitary or in pairs in the leaf axils, growing both in my front lawn and on the allotment site, is common vetch (Vicia sativa). [Spring vetch (Vicia lathyroides) has only solitary flowers, lack tendrils, and has only 2 to 4 (exceptionally 5) pairs of leaflets.]

The purplish-flowered vetch, growing in my garden, among other places, is bush vetch (Vicia sepium). This has many fewer flowers per inflorescence than tufted vetch (Vicia cracca), but the inflorescences are close together, so it takes a close look to tell them apart by this criterion.
