Abstract

Foreman, D. B. Notes on the wood anatomy of Idiospermum australiense (Idiospermaceae). Muelleria 6(5): 329-333 (1987), -Results of a study of the wood of Idiospermum australiense using scanning electron microscopy confirm that in mature secondary xylem exclusively simple perforation plates are present whereas in the secondary xylem of seedlings simple perforation plates as well as a few scalariform perforation plates with up to about five bars are found. Earlier reports that had indicated multiple scalariform or scalariform perforation plates were features of the mature secondary xylem are clearly erroneous. Idiospermaceae appears to occupy an isolated position in the Laurales, allied to Calycanthaceae.
