The Bear, or Scrub Oak (Q. nana, Sarg.), is a shrubby tree that creeps in thickets over rocky barren ledges from Maine to Virginia and Kentucky. Its downy-lined leaves vary greatly in their size and lobing. They are obovate, with the three largest lobes at apex, and tapering to the base, with at least one pair of lesser lobes below the broad middle sinuses. There is a resemblance between these and the leaves of the post oak, although the sharp, holly-like spines that tip each lobe and the two sizes of acorns each tree shows in summer prove this species to belong in the black-oak class. The little acorns, which are bitter and set in shallow saucers, are abundantly produced, and bears fatten on them. The species is often effectively planted to adorn rocky areas in parks.
