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.”

4. Describing fossil corals of the extinct order †Rugosa (also called Tetracoralla), that have horn-shaped corals with surfaces covered with ridges.
