Smilax nana - syn. Damacanthus indicus

I liked the old name of Damacanthus which is what I blurt out when weeding around the spinier Bear's Breeches in the garden. Odd little deciduous woody subshrub of congested twisted stems and stoloniferous habit. It has grown on us over the years and has been useful in the plant version of "Stump the Chump".
