SUMMARY

Seeds of 70 species of Eucalyptus indigenous to Victoria are described.

When classified according to seed characters these species form three main groups which are closely related to the major anther groups as used by Ewart (1930).

Parallelantherous species usually have black, lenticular fertile seeds and chaff which is generally red-brown and awl-shaped. Seeds of renantherous species are angular, polymorphic, and not readily distinguishable from the chaff. In the porantherous group, fertile seeds are generally lenticular in shape, but the main feature is a patterned sculpturing on the seed coat.

The subsequent order of species established by Blakely (1934) in his classification based on anther characters is followed in presenting the seed descriptions. Except in Section Macrantherae, seeds of species within each anther section are alike. Although Macrantherae is heterogeneous to a degree, seed characters are uniform within each Series of the Section.

Species with similar seeds, frequently have cotyledons shaped alike, and often belong to the same bark group.
