Ficus stupenda is a member of a small group of large stranglers which produce abnormally large  often very colorful stipules when the plant flushes with new growth. The rest of the year the stipules are no different from normal fig stipules.  Other closely related members of this group include Ficus subgelderii, Ficus xylophylla and Ficus crassiramea. Non related figs with the same  habit include Ficus elastica and Ficus virens.
