Morphology

Ceratopteris + pteridioides

This is a taxonomic binomial (genus + species epithet), so the meaning is directly compositional: it denotes a particular kind of Ceratopteris, i.e. an aquatic/tropical fern. There is no idiomatic or metaphorical shift, so a learner who knows the constituent parts can infer it refers to a species of Ceratopteris.

Etymology

Ceratopteris pteridioides gets its name from old words cerato and pteris, meaning 'horn' and 'fern', because parts of its leaves can look like small horns or wings. That's why the name fits this small water fern people often keep in aquariums.
