A Prickly Cousin

As mentioned earlier this week, I present for your viewing pleasure, Buffalo Bur.  Believe me when I tell you that you would not enjoy touching this rather prickly relative of the Silver-Leaf Nightshade because it is covered with spines that are coated with a painfully irritating toxin.  So, just enjoy looking at it here and you'll be safe!  Thanks to Biker Bear for hosting......
