It is virtually impossible to distinguish between non-flowering plants of T decipiens and T underwoodii. The major difference is one of stature of flowering plants, and the ratio of leaf length to stem height. In T underwoodii the stems are 3" to 8" tall and 1 to 1.5 times the leaf length, whereas in T decipiens the ratio increases to over 3, the leaf size remaining similar.
