The studies for the spring of 1928 are a continuation of previous work and constitute the eleventh contribution to the series. In the present paper seedlings of twenty-three species of plants are described, the germination periods noted, and the seedlings figured. These plants include both native and introduced forms. The seeds were contributed by Arnold Arboretum and other sources, many being the collections of the senior author in the field.
