Unusually high hedges providing some shelter in this lane.
But buffeted by strong winds earlier in the week.

Sibling species! York Groundsel on the left, Welsh Groundsel on the right. I call them siblings because they evolved through hybrid speciation from the same parent species; Groundsel and Oxford Ragwort.
Both arose as brand new endemic species recently, probably in the last century and a half.

From the Temenos sculpture, Middlesbrough; possibly Common Ramping Fumitory? And a rayed Groundsel, which is probably the subspecies var.Hibernicus?

Most of the Suffolk sand quarry I monitored this week was very brown and crispy, but Common Evening-primrose, Sticky Groundsel (a member of the #DaisyFamily) and Panicled Willowherb were all doing just fine...

Fun science update here: this lovely creature is a new species! I didn't discover a new one, she's just got a new name because it turns out she's different than Perilampus hyalinus. Meet Perilampus seneca 💙💙

Highlight of the year was meeting Welsh Groundsel (Senecio cambrensis), an endearing but somewhat forgotten endemic evolved from a hybrid of Groundsel & Oxford Ragwort. Surveying the few remaining sites I found 153 plants. That’s the total world population, making it 16 times rarer than pandas.
