Rosa multiflora Thunb. ex Murr.
Photographer: James W. Amrine Jr., West Virginia University
Description: A dissected hip: the soft fruit shell is on the right (typical of mid-November), five normal-sized seed are at the upper left, and three "dwarf" seed, representing unpollinated ovules at the lower left; note the abundant, sharply tapered fibers that are always present in the hip; they irritate the digestive tract of song birds, causing the seed to move quickly through the gut (in just a few hours).
