@LorenzoTheCat Poinsettias (euphorbia pulcherrima) are particularly bad because as a euphorbia it's latex is toxic to to the touch. The close relative, the spotted spurge (euphorbia maculata) is an obnoxious weed, because cutting it can get the latex all over. Basically, don't cut poinsettias. https://t.co/Pf2JARQ3Rh

A few things ending up on paper this week. Euphorbia maculata, Mentha sp, Cynodon dactylon and Lotus angustismus. #WildflowerHour @BSBIbotany @wildflower_hour https://t.co/zGwKzFoelY

It's weird how I never even considered Hypericum at the time but with Euphorbia maculata fresh in my mind from a week or two ago, the lack of flowers and the unusual habitat for Hypericum humifusum (I'm used to seeing it on heaths or in acid woodland) it never crossed my mind.
