Dry uplands. rUTICACEAE (Nettle Family) Plants with stipules, and monoecious or dioecious or rarely (in the elm) perfect flowers. A large family mostly tropical. ULMUS Trees with alternate, serrate, pinnately-veined leaves and stip- ules which soon drop ofif. Flowers mostly polygamous, upon the last year's branches. Fruit winged all around, one-seeded. The flowers are purplish or yellowisli, in lateral clusters, appearing in early spring. The leaves are strongly straight-veined, short petioled, and oblique or unequally somewhat heart-shaped at base. U. fulva, Slippery Elm. Flowers nearly sessile. Leaves very rough above.
