Courtesy Acta Horticulturae, 1977 The cranberry industry of the United States is now about 150 years old. It has grown to a sizeable and important economic enterprise in the states of Massachusetts, Wis- consin, New Jersey, Washington and Oregon. In New Jersey, which now ranks third in cranberry pro- duction, a record crop of 250,000 barrels was produced in 1974. Yields per acre have risen sharply from 19 bbls. per acre in 1950 to in 1974. Prominent in the several factors which have con- tributed to this is the more ef- fective pollination achieved by the more intense use of honey bees. The cranberry flower is typically entomophilous. A good description of the anatomy of this flower is given by Chester Cross (1). This delicate, pretty, little structure, which has a hardiness which belies. its appearance, possesses the classic adaptations which make it attrac- tive to bees. The bright white to pinkish corolla is easily seen. The tight ring of eight stamens clustered around the base of the pistil, just above the nectaries, forces the bee seeking nectar to insert its pro- boscis down through the ring. As a R. F.

The fact that the blossom hangs downward facilitates transfer of pollen to the insect. The collection of pollen by the bee is enhanced by its very energy. The activity of its relatively heavy body on the very light flowers, attached to the slender light flexible uprights, sets up jar- ring and vibrating motions which cause dehiscing of pollen. To com- plete nature's scheme, the pro- minent pistil is
