Rugosus
/roo-GOH-sus/🏷️ Taxonomy●● Intermediate
Also known as: rugosa, rugosum
A texture epithet describing a surface covered in wrinkles, ridges, or corrugations — more pronounced and coarser than bullatus, less regular than costatus. Rugose surfaces often result from the veins being prominent and the tissue between them sunken. Appears as rugosus (masculine), rugosa (feminine), or rugosum (neuter).
Etymology
From Latin rugosus, meaning "wrinkled" or "full of wrinkles," from ruga (a wrinkle, fold, crease).
Example
“Rosa rugosa (rugose or Japanese rose) has the most famously wrinkled leaves of any garden rose — a texture so distinctive it has become the defining identity feature of the entire species.”
