Hmm, this might actually suit P. violacea more, given the leaves appear quite small. I don't have the measurements of these plants but for P. violacea "leaves 2–6 mm long and wide on a petiole 0.3–1 mm long", compared to P. incisa "leaves 8–30 mm long and 4–12 mm wide on a petiole 1–10 mm long". Not sure what features you were considering?
