Morphology

Lyginopteridales = Lyginopteris (opaque) = Lyginopteris + ales

Formed by adding the taxonomic suffix '-ales' to a Latinized genus name; this technical taxonomic formation is not transparently meaningful to average learners.

Etymology

Lyginopteridales comes from the fossil name Lyginopteris and the scientific ending -ales meaning 'order'. Lyginopteris likely combines an old Greek idea of 'willow' or 'flexible' with -pteris meaning 'fern', so the name helps us picture an 'order of willow-like, fern-like fossil plants'.
