About
A notable epiphytic bromeliad, *Catopsis berteroniana*, is known for its unique ability to form phytotelmata (water pools) in its leaf structures, which it uses to absorb nutrients. Although sometimes thought to be carnivorous, the plant obtains nutrients through a complex process involving specialized glands and mutualistic relationships with aquatic life.
Field notes
Morphology
The plant has elongate, erect leaves that overlap to form tube-like structures. These leaves feature sessile glands on the epidermis and are characterized by the presence of a white, slippery powder that reflects ultraviolet light.
Distribution & habitat
Found in the neotropics, ranging from southern Florida to southern Brazil. It thrives above tree canopies, particularly in humid environments like Everglades National Park, often at the apex of red mangroves.
Ecology
The plant's phytotelmata host a complex food web, supporting 11 inquiline species, including mosquito larvae like *Wyeomyia mitchellii*. A mutualism exists where the plant provides habitat, and the larvae help break down nitrogenous nutrients for faster absorption. The plant also obtains nutrients from algae, which are essential to the internal food web.
