veinless
Lacking visible striations
Veinless means lacking veins.
The word applies literally to leaves or wings without visible vein structures: a veinless leaf mutation.
In anatomy, it might describe tissue or areas without blood vessels.
The term is technical and uncommon outside botany and biology.
