The separation of Myrmecodia erinacea and alata is very difficult to impossible. 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, separation is almost impossible in some collections . I have numerous locality forms in my collection and will offer some of them over the next few years.In this case it is the most extreme M. erinacea I have ever come across. With typically wavy and embossed leaves that are also extremely long and narrow. A marvellous form!
Unfortunately, its origin cannot be traced.
