%X Fungal infestation of pollen wall and cytoplasm is common in Strelitzia and Ravenala (Strelitziaceae) after anther dehiscence. The exine, rarely more than 0.1 μm thick, is not degraded by these infestations. Fungal hyphae enter the pollen grain cytoplasm through ruptures in the exine caused by osmotically shocked protoplasm or mechanical damage. We find no evidence that fungal enzymes or other microbes breach the thin exines of this family.
