Squint your eyes and think of spinach

I had difficulty getting the leaf texture right - it's supposed to be puckered up like a spinach leaf. This Solanum rostratum Dunal has made its first appearance, after 22 years of gardening, at Longears. You know you have a bad 'un when the extension service says of this weed "Nasty, nasty, nasty"! The spines are very strong and sharp and appear on all parts of the plant - even on the leaves! It is considered a noxious weed in 46 states and that does not imply that this Solanum behaves demurely in the other 2 states! In the interest of science, I let mine develop seed so that I could draw it....but I'm heading out to the garden with a thick pair of gloves and a spade to uproot it right now!
