Morphology

order + Lyginopteridales

This is fully compositional: 'order' (a taxonomic rank) combined with the taxon name 'Lyginopteridales' yields the meaning 'the taxonomic order of the Lyginopteridales'. Biological naming conventions of rank + taxon are regular and cross-linguistically familiar, so a learner who knows both constituents can derive the meaning. Although the taxon name is specialized, the structure and semantics are predictable rather than idiomatic.

Etymology

Order Lyginopteridales groups ancient plants called seed ferns that looked like ferns but made seeds instead of spores. Imagine a plant with fern leaves that also makes seeds — that clear picture is why the name refers to an extinct group of fossil seed-producing plants from the Devonian period.
