| Abstract: | This paper deals with the anatomy of two- and three-ovulatecone scales which are found occasionally in the cones of A.Bidwillii. The manner in which each ovule receives its vascularsupply from bundles lateral to the ovule is discussed, togetherwith a hypothetically primitive type of araucarian cone scalewith three ovules possibly resembling the fossil Schizolepis.The interpretation of the vascular system of the scales as givenin this paper is a correction of that presented in the firstpaper of this series by the same authors. |
