Fresh leaves are a very distinctive pale grey below and dark glossy green above but in herbarium collections the leaves dry all pale grey to buff cream.
Ficus corneri is a member of a complex of 3 closely related generally rare species including Ficus lowii and Ficus soepadmoi. The relationships need further investigation, and the current names may well be subject to change in the future.
