Shrub or small tree, 2-4 m. (occasionally to 6 m.) high, sometimes becoming scandent; leaves ovate-oblong to elliptic-ovate, up to 30 cm. long and 12 cm. wide, acuminate at apex, rounded at base, sometimes slightly emarginate, crenate- serrate, crenulate, or subentire, glabrescent, or occasionally hirsutulous on the principal nerves beneath; plants dioecious, the inflorescences dichotomous, much shorter than the petioles, staminate flowers sessile in glomerules, glabrous; pistillate flowers short-pediceled, usually borne singly.

With much the same distribution in Panama as the preceding species; also in Jamaica and Colombia.

Note
|
Two forms are represented by the specimens cited below; one has relatively small leaves which bear punctiform cystoliths densely massed all over the upper surface, and agrees best with type material of U. elata in the British Museum; the other has leaves generally more than 15 cm. long, the cystoliths being short-linear and radiating from the center of the areoles to the veinlets. This latter variant has been confused with U. alceifolia (Poir.) Gaud., of French Guiana, which apparently cannot be separated from the common U. caracasana.
