Morphology

group + Pteridospermae

The phrase is compositionally built from 'group' (a set of things) plus the taxonomic name 'Pteridospermae' meaning extinct seed-bearing plants, so the meaning 'a group of Pteridospermae' is directly derivable. The syntactic pattern 'group + noun' is cross-linguistically common and follows standard noun modification, making it transparent to a learner who knows both constituents.

Etymology

Group Pteridospermae takes its name from old Greek: pterido- meaning 'fern' and -spermae meaning 'seeds', because these fossil plants had fern-like leaves but made seeds. So the name helps you remember they were a group of extinct 'seed ferns'.
