Add to ORKGIn the proceedings of the Iowa Academy of Science, 1917, we published a paper on the germination and the juvenile forms of some oaks, mostly species native to Iowa. In this paper some of the literature on the subject was given. C. S. Sargent has touched on the germination of many of the species of North America, in some cases in detail. Germination of exotic species is described by Tubeuf. It seemed well, therefore, to continue observations on the germination of Iowa species, and a few not native to the state are included. Little specific seems to be known about the vitality of tree and shrub seeds. The statements made are usually quite general
