AW: [Aroid-l] Frank`s Xanthosoma ID

---

Thanks to you both for your quick replies. I thought X.sagittifolium has greenish leaves. The one I have has dark blueish/green leaves. But maybe it is just a variation. I found this photograph on the web which says that it depicts a X. lindenii "purpurea". The plant on the picture resembles very much my specimen. You think it is mistyped?
