There is distinct evidence of a secondary growth in thick- ness. The branching was always dichotomous. The leaves were very similar to those of Lycopodium, and were penetrated by a single ' vascular' bundle. The fructifications known as Lepidostrobus are cone-like structures, not unlike fir-cones in appearance, consisting of densely packed sporo- phylls. On the upper side of each leaf is a single sporange, often of considerable size.
