Pattern of the Seed Surface of Goodenia and Related Genera

Abstract

The surface patterns of seeds of 88 species of Goodenia and related genera were examined under scanning electron microscope and light microscope. With use of sections as well, the patterns were resolved into six attributes of which each was present in one of at least two states. Certain combinations of states of attributes are used to define terms which are used for purposes of taxonomic description. Six such terms are defined in this way. The results indicate that previous taxonomic arrangements are unsatisfactory. A brief commentary on possible evolutionary trends is provided and the relationships of the various satellite genera to Goodenia are discussed.
