Studies on the Germination of Some Woody Plants

The following brief study is a continuation of those previously reported to the academy. In the past these papers have been published in the Report of the Academy. One paper is in the hands of the Secretary. It is hoped to finally report on the germination of all of the native woody plants of Iowa, as well as the germination of a few exotics. In a study of the germination of these plants one is apt to notice striking characters that cannot well be described. For instance, the young dogwood plants have an aspect peculiar to the family. For the first time, this year, a study has been made of the sugar maple (Acer saccharum). The glaucous character of the under surface of the leaf is just as pronounced in the young plants as in older leaves. Some seeds, like the maple, walnut and oaks, make a rapid progress in growth during germination. The eleagnus or oleaster on the other hand makes little progress at first
