The clear separation of Myrmecodia erinacea and alata is very difficult, as transitional forms are found. Normally, M. erinacea has rather narrow leaves with wavy leaf margins and an uneven, quasi-embossed leaf surface, while M. alata has rather broad, smooth and unwavy leaves. However, the separation is almost impossible with some collections. I have numerous site forms in my collection and will be offering some of them over the next few years.In this case, it is a fairly clear M. alata with non-undulating broad leaves.
