Am i correct in saying that my Anthurium marmoratum is actually a form of Anthurium angamarcanum because all Anth. marmoratum are actually just variations of Anth. angamarcanum.

This does suggest that any plant labelled Anthurium marmoratum is actually a type of Anthurium angamarcanum and their is no such plant as Anth. Marmoratum.

Basically, are these two species of Anthurium the same plant with different sames.
