A Cyphostemma with tomentous (furry) leaves and thick, knobby pachycaul trunk (caudex). Vines emerge in spring. Awesome natural bonsai. "Aff" means resembling but not the same, so this species resembles adenocaule but isn't quite the same. I can't really see the resemblance but it's still a neat plant. Uncommon. 6" pot size, seed grown.
