Abstract

The present communication is concerned with an incomplete megastrobilus belonging to the Araucariaceae. The specimen is a portion of a cone having the central axis with several, compact, spirally arranged non-ligulate cone-scales; mostly with a single, completely embedded seed, but very few (here seen in only two cone-scales) in their early stages of development possess two unequal groups of nucellar cells.
