or Asperifolious, among botanists, such plants as are rough-leaved, having their leaves Asperifoliæ leaves placed alternately on their stalks, and a monopetalous flower divided into five parts.—They constitute an order of plants in the *Fragmenta methodi naturalis* of Linnæus, in which are these genera, viz. tournefortia, cerinthe, symphytum, pulmonaria, anthusa, lithospermum, myosotis, heliotropium, cynoglossum, asperugo, lycopsis, echium, borrage: *magis minuscularae, mucilaginosae, et glutinosae sunt.* Lin.

In the present system, these are among the pentandrae monogynia.

**ASPERIFOLIÆ PLANTÆ**, rough-leaved plants; the name of a class in Hermannus, Boerhaave, and Ray's methods, consisting of plants which have four naked seeds, and whose leaves are rough to the touch.

In Tournefort's System, these plants constitute the third section or order of the second class; and in Linnæus's Sexual Method, they make part of the pentandrae monogynia.
