PTELEA TRIFOLIATA.--Hop Tree, or Swamp Dogwood. North America, 1704. A
small-growing tree, with trifoliolate, yellowish-green leaves placed on
long footstalks, and inconspicuous greenish flowers. The leaves, when
bruised, emit an odour resembling Hops. P. trifoliata variegata is one
of the handsomest of golden-leaved trees, and is well worthy of
extensive planting. It is preferable in leaf colouring to the golden
Elder. Perfectly hardy.
