Notes: Distinct from other C. foliosus vars. in leaf vestiture, with abundant hairs on abaxial leaf surfaces and young stems that often form a dense mat, obscuring tertiary venation (vs. glabrous or usually sparse abaxial hairs when present in other vars.). Similar to C. tomentosus; differentiated by undulate leaves with lamina that are often folded lengthwise (vs. plane margins with lamina that are flat in C. tomentosus). See Systemic Botany 42(3):529-542 (2017) for original description. |
