Having rugae or wrinkles, creases, ridges, or corrugation.
Rugged, rough, unrefined.
Having a rough, wrinkled, or wavy surface; commonly in parasynthetic usage e.g. "rugose-veined" or "rugose-leaved".
Petraea foliis rugosis ovatis. The oval, rugose-leaved Petraea. The root is brachiated; the shrub rises to ten feet high: the leaves are three inches long, an inch and a half broad, even at the edges, and very rough to the touch: (Note: In modern nomenclature, the plant in question probably is Petrea rugosa, as the spelling "Petraea" does not seem to match any extant genus,)
From Latin rūgōsus (“wrinkled”).
