I've been looking at different pictures of Wentii & Metallica. It appears the Wentii has a green stem and Metallica has a burgandy stem. Is this correct?
I separate a few larger pots but has lost tags and want to be sure I label them correctly.

These are what I think are Metallica.

And this is what I thinks is Variegated Wentii

Yes, the wentii has green petioles and the metallica mottled or burgundy petioles. There is a "green" metallica but the overall look of the plant is the same as the burgundy type. If you have only the burgundy type, then that coloration is a good way to distinguish the two plants. Also, wentii leaf blades are peltate, while the metallica leaf blades are not.

Thanks Lari
Yes I only have the one type of 'Metallica".
