These photos are to show you how to tell P. wandae and P. grande apart. P. wandae has frills that form around the bud. (2nd image) P. grande top does not have that carerteristic. Platycerium superbum looks similar to P. grande but forms only one spore patch.
There in these photos I am showing that P. wandae has 2 spore patches not like P. superbum that has only one. P. grande has the same 2 spore patches but does not have frills around the bud.
