Prof. Geo. G. Groff sends us specimens of fruit from a tree at Lewisburg. He has never seen aments on it. Another tree about 100 yards away bears aments, but he has never seen fruit on it. These trees therefore, seem to be dioecious, as the books on coniferse describe the species to be. It still leaves the cases of isolated trees bearing fruit in doubt. Does the plant really have male and female blossoms on the one tree sometimes? Or is the pollen wafted from long distances as pine tree pollen often is?
