Another one I forgot to add to the list from yesterday's vascular finds was Oxeye Daisy, which has finally begun to flower.
Also while tracking down Bush Vetch in Rose I noticed that while Common Vetch (Vicia sativa) is an annual Bush Vetch (Vicia sepium) is a perennial. It does look different, with a more muted purplish flower rather than the garish pink of V.sativa. Structurally the noteworthy point for keying is that the lower calyx is extended in V.sepium. With yesterday's haul I scooped 20% of my remaining target for vascular plants, and I'm still contemplating the possibility that the target of 500 is achievable within the first six months. It will be interesting to see what I end up with.
