Morphology

class + Psilotatae

This is a compositional taxonomic phrase: 'class' names a biological category and 'Psilotatae' denotes the whisk-fern group, so a learner who knows both constituents can infer it means the taxonomic class comprising Psilotatae. Taxonomic constructions of the form category + name are regular and cross-linguistically common, making the meaning directly derivable from the parts.

Etymology

Class Psilotatae may come from the Greek word psilos, meaning 'bare' or 'smooth', because these whisk ferns have a very simple, almost leafless look. So the name helps you remember that this group includes primitive plants with no true roots and very simple spore organs.
