Example Sentences

• "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,)"
• "The original leaves were flat and very rugose, and almost hid by the numerous single-stemmed flowers; while the leaves produced in the umbellate state were larger, more upright, and less wrinkled."
