Morphology

class + Equisetatae

The meaning is transparently compositional: 'class' denotes a taxonomic category and 'Equisetatae' names the group (horsetails), so a learner who knows both constituents can infer it refers to the taxonomic class containing horsetails. Taxonomic naming patterns (class + taxon name) are regular and cross-linguistically familiar, making the expression directly understandable from its parts.

Etymology

Class Equisetatae comes from Latin parts: equi- ('horse') and -seta ('bristle'), because the long, thin stems of these plants look like a horse's tail. That's why scientists used class Equisetatae to name the group of plants that includes horsetails.
