Abstract

For continuation of our studies of germination, there were collected in the fall of 1925 seeds of about 50 species of trees and woody plants. The source of these seeds is in large part local, with a number sent in by the senior author, from Arizona and California. These seeds were planted in the greenhouse at time of collection. Duplicates of about 20 species were held out of doors for stratifying, under natural conditions. These were removed to the greenhouse March 25, 1926. At time of April 20, only 2 species had germinated, Pinus Lambertiana and Caragana arborescens.
