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.
