Morphology
This is a straightforward taxonomic label combining the noun 'class' (a category/rank) with the proper name 'Gnetopsida' (a group of plants); if a learner knows both constituents, the meaning — the class named Gnetopsida — is directly compositional. The rank+name pattern is common across languages and scientific nomenclature, so the sense is transparent to learners who know the parts.
Etymology
Class Gnetopsida comes from the plant name Gnetum plus the ending -opsida, which means 'a class' or 'group' of plants. So the name tells you this is the plant class built around Gnetum, thought to sit between cone-bearing trees and flowering plants.
