Abstract

SEM observations on seeds of Striga spp. and Buchnera americana (Scrophulariaceae).

Abstract

Seeds of Striga asiatica, S. gesnerioides, S forbesii, S. aspera, S. brachycalyx, S.hermonthica, S. angustifolia and Buchnera americana were examined by SEM. The surface patterns of the seeds in both genera resembled each other closely, especially those of S. angustifolia and B. americana. Some Striga spp. could be clearly distinguished by their surface characteristics, while others were very similar. The taxonomic value of the seed surface features of Striga and Buchnera is discussed.
